	What is the format of the Floating Point data structure in the MP920, MP930, MP940 series products? Posted Date: 07/13/2004 Answer: The Format is "The IEEE standard for floating point, single precision (32-bit) arithmetic" The most significant bit is the sign, while the rest is the data area. This is described very well and in significant detail at the sight below: http://www.psc.edu/general/software/packages/ieee/ieee.html If a programmer specifies a Floating Point number as "MF10000", the data structure in the MP memory is attached in the .PDF file below for reference.

	What is the difference between Z registers and A registers when used in Function Blocks? Posted Date: 04/30/2002 Answer: Z and A registers are both working registers that are used inside function blocks Z registers are Global Internal Function Block registers consisting of 64 words of shared memory space within the CPU (Internal refers to internal to the function block). These registers can be represented in bit, 16-bit word, long word, and floating point, and are working registers available for use specifically within function blocks. Since they are global, several function blocks have access and can modify the stored value. A registers are Local External Function Block registers (External refers to registers used inside the function block, but register space that is reserved outside of the function block). When a function block is defined, a block of memory is reserved by defining the starting address and the data size. This block of memory can be defined as General Global register space (M registers) or Local Drawing register space (D registers). Example: If a function block is defined at address DA00010, and to utilize 10 registers, then registers DW00010 thru DW00019 should be reserved by the programmer for the use of that specific function block. In this case, AW00000 would be mapped directly to DW00010 each scan. When the function block is being used in a drawing, to monitor an internal working register such as AW00000 in this example one would monitor DW00010. - If D registers are used, then A registers are limited to the D register limit for local drawings - quantity of 16383 per drawing. D registers consume programming memory and expand according to need (limited to programming memory available and number of drawings). - If M registers are used, then A registers are limited to the M register limit globally for the controller - quantity of 32767. M registers have a fixed memory space.

	What is the difference between the I/O on the Sigma II and the MP940? Do both need to be used? Posted Date: 04/26/2001 Answer: There is a difference between the two I/O ports and in most cases both will be used, and is recommended. The Sigma II I/O (CN1 connector) is mostly dedicated I/O with some user defined I/O. The MP940 (I/O connector) is all user defined. Below is an explanation of the inputs and outputs for each device: I/O (MP940): - 8 digital inputs (programmable, isolated 24VDC) - 1 high speed latch input (for external encoder position latching), DC Voltage: 24, 12, or 5 VDC - 1 external encoder input (must be 5 VDC) - 8 digital outputs (programmable, isolated 24VDC) - 1 Analog Output (+/- 10.75VDC, 16-bit resolution, 328uV/bit) CN1 (Servopack): - 4 digital inputs (programmable, isolated 24VDC) - 1 high speed latch input (for motor encoder position latching, can be used as programmable input if latch is not necessary, 24VDC) - 2 overtravel inputs (can be used as programmable inputs if overtravel switches are not necessary, 24VDC) - 1 analog input (+/- 12VDC, 16-bit resolution) - 3 digital alarm code outputs (open collector) - 1 digital servo alarm output (This output will only indicate Servopack alarms, some MP940 alarms will not activate this output.) - 3 digital semi-programmable outputs (These can be configured for various functions which the Servopack activates. For example, one of these must be used to control the brake if a servomotor with a brake is used. 24VDC) - 1 motor encoder output If the system requires I/O from both the MP940 and the Servopack than two breakout cables will be needed. Yaskawa recommends using the standardized I/O (such as Overtravel, SON, and Brake Control) to maintain consistency and system robustness.

	What is the difference between the "I" and "J" extended I/O options for the SMC-2000? Posted Date: 07/13/2004 Answer: With the SMC-2000, both the "I" and the "J" options are extended I/O options that add 40 inputs and 42 outputs to the controller. The difference between the two options is the electrical specifications of the outputs. The "I" option uses "dry contact" outputs. These outputs are capable of switching any voltage up to 200VDC (max 0.5A, 10W). Each group of seven outputs has its own common reference, so multiple voltages can be used. The "J" option uses solid-state output. The outputs are all 24VDC (100mA per point), but because they are solid state, there are no mechanical parts to arc and/or wear out. If a system uses mostly 24VDC outputs (this is very common), Yaskawa recommends the "J" option for it's longer life. If there is only one or two outputs that are higher voltage or AC voltage, it is best to use relays to control these outputs. Both the "I" and "J" options use two 50-pin high-density connectors for wiring. This is the same connector at the I/O connector of an SGDH or SGDB amplifier, so the same terminal block connector can be used. This is part number JUSP-TA50P.

	What is the difference between STN and TFT on an LCD HMI? Posted Date: 07/13/2004 Answer: LCD: Abbreviation of liquid crystal display, a type of display used in digital watches, many portable computers, and industrial HMI products. All of the EXOR HMI Products have LCD screens. LCD displays utilize two sheets of polarizing material with a liquid crystal solution between them. An electric current passed through the liquid causes the crystals to align so that light cannot pass through them. Each crystal, therefore, is like a shutter, either allowing light to pass through or blocking the light. Monochrome LCD images usually appear as blue or dark gray images on top of a grayish-white background. Color LCD displays use two basic techniques for producing color: Passive matrix is the less expensive of the two technologies. The other technology, called thin film transistor (TFT) or active-matrix, produces color images that are as sharp as traditional CRT displays, but the technology is expensive. Recent passive-matrix displays using new CSTN and DSTN technologies produce sharp colors rivaling active-matrix displays. Most LCD screens used in notebook computers are backlit to make them easier to read. STN: A technique for improving LCD display screens by twisting light rays. In addition to normal supertwist displays, there also exist double supertwist and triple supertwist displays. In general, the more twists, the higher the contrast. Supertwist displays are also known as supertwist nematic (STN) displays. TFT Abbreviation of thin film transistor, a type of LCD flat-panel display screen, in which each pixel is controlled by from one to four transistors. The TFT technology provides the best resolution of all the flat-panel techniques, but it is also the most expensive. TFT screens are sometimes called active-matrix LCDs Product Group/Line: Controllers, General Controllers Topic/Sub Topic: Ask a Technical Question, Specifications Document Number: MNEN-5CJMEN Published Date: 07/13/2004 Share \| Rate Rate this article :	07/13/2004
	What is the difference between MODBUS and Memobus? Posted Date: 04/26/2001 Answer: The Memobus protocol is almost identical to the Modbus protocol. All of the function code calls are the same. The difference between the two protocols lies in the way the data is organized in the registers. 16-bit words are handled the same in both protocols, but addressing individual bits in a 16-bit word is accomplished differently. 32-bit long integer and floating point numbers are also handled differently by the two protocols. The attached document provides a more in-depth comparison between the two protocols. If a complete specification is needed, it can be obtained by calling Yaskawa at (800) YASKAWA option 42 (Publication: SIE-C815-13.60E).

	What is the difference between Manual Mode and Auto Mode on the Single Phase Converter? Posted Date: 09/18/2017 Answer: Manual Mode has the converter actively switch any time the run command is on. Auto Mode will detect when the motor is drawing power then start actively switching as the load increases. Auto Mode can be more efficient with simpler control wiring, while Manual Mode can be used for more dynamic loading applications.

	What is the difference between a YS-13 and YS-15 cable? Posted Date: 07/13/2004 Answer: The YS-15 Cable is recommended when using the MP940. The YS-15 cable, also known as a Programming Cable, is currently used to connect between a PC and the MP940 via RS232 (port#1 on the MP940). The YS-15 cable supports all revisions of the MP940 product. The YS-13 cable is an older style cable which was used on MP940 versions A03 and lower (it is not possible to communicate to an MP940 versions A05 or greater using a YS-13 cable). Firmware Versions A03 (of the MP940) and lower only supported two wirre RS422/485. Firmware versions A05 and above now support both two and four wire. Hence, CTS and RTS are lines now supported in the MP940. The YS-15 cable loops back these lines to allow communications when the PC does not use the CTS/RTS lines. A diagram showing the differences between the YS15 and YS13 cables is shown below.

	What is the current requirement of the 24VDC control power supply for 400V Sigma II amplifiers? Posted Date: 01/03/2002 Answer: The 400V Sigma II amplifier requires 24VDC for its control circuit. The specification for this DC power supply is: 24VDC +/- 15%, 1A. For amplifiers with capacity of 6 to 15 kW , use of an isolated 24VDC power supply for each amplifier is strongly recommended.

	What is the current rating for the Run and Fault output contacts on a GPD 515/G5? Posted Date: 07/13/2004 Answer: It is a 1Amp at a maximum voltage of 250 VAC or 30VDC. The 30VDC rating applies to inductive loads such as relays and contactors. DC coils draw more of an arc when the contact opens than AC coils and arcing could eventually lead to premature failures of these contacts. Adding a reversed biased diode to suppress this arc across the DC coil is recommended in all cases. If these outputs are being used by the customer for Non-Inductive loads, then the 1Amp rating is still fine at 48VDC.

	What is the cause of error code "Error in Native Code Generation" when attempting to compile a MotionWorks IEC program? Posted Date: 10/08/2015 Answer: There can be multiple causes for the "Error in Native Code Generation" but they are often caused by errors in the allocation of variables in the MP3000iec controllers. Detailed information can be found in the attached document (TN.MPIEC.01). The error can also be caused by incompatibility between libraries and the MotionWorks IEC software. For example, Yaskawa's Cam Toolbox v2.4 and later require MotionWorks IEC v3.x to compile correctly. The MotionWorks IEC v2.x user would either need to use an older version of the toolbox (v2.3 or earlier, which may not have all functions required for the application) or upgrade MotionWorks IEC v3.x.
