	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 JEPMC-W6060 and JZSP-CKI01 cables? Posted Date: 06/25/2014 Answer: Both cables are 50 pin with 3M connectors at one end and pigtails at the other end, and are interchangable with each other. JEPMC-W6060-xx cable: 1. This cable is typically selected when specifying MP920 amd MP2x00 System Components, when connecting external I/O to a module. (SVA-01 CN5, DO-01/DI-01/PO-01/CNTR-01 CN1 & CN2 / LIO-05 and LIO-05) 2. "xx" indicates the cable length (05=0.5m, 10=1.0m, 30=3.0m) 3. The wire color code for the cable is attached below (JEPMC-W6060-xx Pinout and Color Code .pdf) 4. The JUSP-WA50P-xx cable may also serve as a substitute cable JZSP-CKI01-x(A) cable: 1. This cable is typically selected when specifying SGDH, MP940, NS300, NS500, NS600, NS100 cable components. a. SGDH/NS300/NS500/NS600/NS100: 1CN I/O connector b. MP940: I/O connector. 2. "x" indicates the cable length (1=1m, 2=2m, 3=3m) 3. "A" indicates the revision level 4. The wire color code for the cable is attached below (JZSP-CKI01-XX.dwg) 5. For wire function on SGDH/NS300/NS500/NS600, see dwg below 6. For wire function on MP940, (See FAQ # MNEN-5CJMPJ) This same type of cable is available with a D-Sub connector in place of pigtails, click this link for more information on the JZSP-CKI0D cable option.

	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. For more information, please refer to the attached document.

	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.

	What is the cause of error 440C 1003 (Unable to add axes group to groupIODriver. Check the validity of the handle.)? Posted Date: 12/11/2017 Answer: The controller was unable to load a configured axes group is indicated by the error 440C 1003 with the description: Unable to add axes group to groupIODriver. Check the validity of the handle. The most likely cause is that the INIT switch of the controller is ON. The INIT switch disallows the loading of any saved configuration. To fix this alarm, turn the INIT switch off and reboot the controller.

	What is the cause of an A.CC Alarm? Posted Date: 08/27/2004 Answer: When using the DD Motor's single-turn absolute encoder as absolute with Sigma II application modules, e.g. MP940, NS600, etc., Pn205 in the Sigma II Renewal amplifier must be set to 0. The application module reads Pn205 at power on, if Pn205 is not set to 0, an A.CC alarm will be generated. For more information on Alarm Codes, please see FAQ MNEN-5CJMGY.

	What is the brake power supply tolerance for brake motors? Posted Date: 03/08/2016 Answer: The nominal power supply voltage required is 24VDC (+10%, - 0%). A separate isolated power supply should be used for powering the brake(s) in a system. Combining brake activation with shared logic power supply can cause unintended noise in the system.

	What is the best way to correctly use the RETURN instruction? We had some issues in some cases when the Functions blocks get stuck, or needs an additional trigger. Posted Date: 10/06/2011 Answer: The RETURN causes the controller to stop executing code in a function or function block POU, and immediately go back to the POU that called the function. This is good for execution efficiency, but can cause problems if not used correctly. It's efficient because the code below the RETURN becomes dormant. (Not scanned) Never allow the RETURN to execute if any code below the RETURN is still "Active." Active means an Execute input for a function block is high, or a function inside the function is "Busy," or an R_TRIG has a high input, basically any code that will become confused after "sleeping." For example, if a RETURN takes place while an MC_Move_Absolute.Execute is high, MC_MoveAbsolute will not notice when the execute logic goes low. Next time the function is executed, MC_MoveAbsolute will not notice the rising edge for execute, because to the MC_MoveAbsolute, it has always been high. For examples, look at the code used in nearly all of Yaskawa's Toolbox functions. We use a technique that only allows the RETURN to take place if many conditions are met.

	What is the best method to convert a STRING into a BYTE array and vice versa? Why is this conversion useful? Posted Date: 04/22/2014 Answer: STRINGs are special data types that contain hidden information which indicates the actual length of the data within the STRING variable. Sometimes this hidden data can be interpreted as part of the actual string contents. See the attached PDF for a detailed answer.

	What is the battery current draw of the absolute encoder of the Sigma-5 motors with and without control power? Posted Date: 06/18/2013 Answer: The Sigma-5 absolute encoder's current draw when control power OFF is 20uA approximately and 30uA maximum with surrounding temperature at 25°C. Conversely, the Sigma-5 absolute encoder's current draw reduces to 3uA when control power is ON with surrounding temperature at 25°C . It is recommended to use lithium battery where its capacity depends on the number of axes used.
