	Other than OLV/PM parameters, is there other causes of OPE08? Posted Date: 11/27/2012 Answer: Although oPE08 is described as 'A function has been set that cannot be used in the motor control method selected', there is a specific parameter that, on the surface, has very little to do with the motor control method. This parameter is L6-02 and L6-14, Torque Detection Level 1 and Motor Underload Protection Level at Minimum Frequency, respectively. If L6-02 < L6-14, oPE08 will be triggered. Because the L6 parameters have to do with Torque Detection, it was determined this was related to motor control method, i.e. Torque, instead of Current (see attached).

	On the V7 Drive are the Logic inputs and the Logic Common terminal (SC) electrically isolated from the Frequency Reference Common (FC)? Posted Date: 07/13/2004 Answer: Yes. The Logic Inputs (S1..S7) and Logic Common (SC) are electrically isolated from all other terminals including FC and chassis ground. In fact all circuit board connections are DC isolated from chassis ground. However, 'Frequency Common' (FC) is 'OV' (read 'zero volts') which is the circuit board common. FC is not isolated from the MODBUS terminals (S+,S-,R+ and R-). Note: Earlier versions of the V7 Drive were named GPD 315/V7, GPD 315 or VS Mini V7.

	On the GPD 515/G5, If Terminal 1 to 11 are closed, but the GPD515/G5 inverter still does not run. What is wrong? Posted Date: 07/13/2004 Answer: There are 3 possible reasons that the drive is not running: 1. The drive is receiving no speed reference. If this is the case, the Run light will be on, and the Stop light will be flashing. 2. The inverter is not using the input terminals for the 'Run' command. Set Parameter 'b1-02' to '1: Terminal'. 3. The inverter is being placed into the 'drive' mode with the run command at Terminal '1' already engaged? Remove that contact closure and then reapply it.

	On the GPD 515/G5, can the 15V at pin-15 power a proximity sensor? Posted Date: 07/13/2004 Answer: Maybe. The 15V at pin-15 is referenced to board common (pin-17) and rated to source 20mA max. Unless the output of the proximity sensor is isolated, using the sensors output to sink one of the logic inputs would necessitate connecting logic common (pin-11) to board common (pin-17). This could cause potential GROUND LOOP problems with other inputs.

	On an MPiec Series Controller, what information is cleared when the "Initialize SRAM" feature is executed? Posted Date: 08/16/2013 Answer: Initializing SRAM will reset or initialize the following data: 1. Absolute Encoder offsets stored in the MPiec Controller by the MC_SetPosition function block. Use a homing procedure after initializing SRAM to ensure that the correct absolute encoder offsets are re-established. 2. IEC Global variables marked as 'Retain' data. Reload any necessary retained (non-volatile) variables. 3. Alarm history.

	On an MP2600iec, is it possible to use the CN-13 latch input instead of the CN-1 latch input? Posted Date: 02/28/2017 Answer: This question comes up if the user does not have a CN-1 cable, but has a CN-13 cable for the Digital and Analog I/O, along with the External Encoder Axis. If there is no external encoder present, using the latch input on the CN-13 connector will result in a recorded position of '0' since the external encoder axis is not moving. So unfortunately no, the latch input on CN-13 is dedicated to the external encoder and cannot be reconfigured to the CN-1 latch input which is dedicated to the servo encoder.

	On a linear motor x-x'-y gantry system, what is the best method to control the two x-axes? Posted Date: 06/06/2003 Answer: The preferred method is to set-up a master/slave relationship using two axes of a motion controller. The motion controller must monitor the linear encoder feedback from both the x and x'. The x' axis must track the position of the x axis. Another alternative is to set-up a master/slave relationship using only one axis of a motion controller. The motion controller would monitor the linear encoder feedback from the x axis and command the x' axis. The x' axis would follow the encoder output directly from the x axis encoder output. Caution should be taken when implementing this method, since each amplifier operates in a different control method and different loop updates may exist. The following example lists the necessary SGDH amplifier parameter settings for a linear motor master/slave application (assuming a linear encoder grating pitch of 20 microns). Master Axis Parameter Settings: Pn000.1=2 Sets amplifier in Force Control. Pn280=20 Linear encoder grating pitch is 20 micron. Pn281=20 Sets encoder output resolution to 20 micron per 20 pulses (or 1 micron per 1 pulse). Slave Axis Parameter Settings: Pn000.1=1 Sets amplifier in Position Mode. Pn280=20 Linear encoder grating pitch is 20 micron. Pn202=256 Electron gear ratio numerator. Pn203=20 Electronic gear ratio denominator. The electronic gear ratio is used to scale the postion command input.

	On a GPD 506/P5 Bypass unit, what is the Normal/Test switch used for and when would it be needed in an operation? Posted Date: 07/13/2004 Answer: The Normal Test switch on the front of the Bypass panel is provided to test or setup the GPD 506/P5 without actually connecting the motor. When in Test mode, the contactor on the input of the inverter is energized bringing three phase power to the inverter but the output contactor is left de-energized. The digital operator can then be used for programming or to issue a run command so that the inverter can be checked for normal operation. Note: A fault message will be displayed on the digital operator when the Test Switch is in the Test position while in Drive mode. This switch should be in the Normal position in Drive mode. Test mode can be used when the Drive/Off/Bypass switch is in either the Off or Bypass position.

	My drive has a CPF25 fault on it, my V1000 manual has no information on this alarm. What are some troubleshooting techniques to apply? Posted Date: 10/29/2012 Answer: The V1000 has a built-in EEPROM. When the CPU reads from the EEPROM, it looks for a 4 byte "Copy protect" code. If the terminal board is not connected, the CPU will be unable to read this (see attached) and give a CPF25 alarm. Additionally, if the memory in the EEPROM on the terminal are not congruent, the CPF25 alarm will show. In this case we will need to initialize the EEPROM by: 1. go into factory level A1-04 = 606 2. change access level to A1-01 = 606 3. EEPROM initialize, A1-03 = 9990 Attachments: 60KB Product Group/Line: Inverter Drives, A1000 Configured, A1000 Drive, V1000 Drive Topic/Sub Topic: Ask a Technical Question, CPF25 fault Document Number: DRV-8ZFM24 Published Date: 10/29/2012 Share \| Rate Rate this article :	10/29/2012
	*Must the data type be the same for every variable in a calculation? I get a compile error when I try (REAL := REAL INT).** Posted Date: 05/26/2009 Answer: IEC 61131-3 enforces strict datatyping. This means that when mixing types as in the calculation: REAL:=REAL * INT; a type conversion function is necessary. Also note that INT, UINT and WORD are all 16 bit values, but WORD is intended to be used with data that might be binary, with AND and OR operations performed on it. INT & UINT are intended for data that will be manipulated with addition, subtraction, multiply, and divide. (analog data.) DataType conversion functions allow operations to a dataype as if it is another. The following are some examples: REAL:=REAL * INT_TO_REAL(INT); BitCode:=(BOOL_TO_INT(Bit2) * INT#4) + (BOOL_TO_INT(Bit1) * INT#2) + BOOL_TO_INT(Bit0); (* BitCode is defined as an INT *) Product Group/Line: Controllers, MotionWorks IEC Topic/Sub Topic: Ask a Technical Question, Programming Document Number: MTN-7M5NXT Published Date: 05/26/2009 Share \| Rate Rate this article :	05/26/2009
	Many new computers do not offer serial communication ports. How is communication possible to Yaskawa products if no serial port is available? Posted Date: 06/25/2013 Answer: Currently most Yaskawa products require serial communication; some do offer Ethernet as an alternative. However, if neither method of communication is available, most computers offer USB (Universal Serial Bus). A USB to serial adaptor device may be used to establish communication. These adaptors are widely available on the Internet and at electronics stores. All current Yaskawa software will work with a USB to serial port adaptor (provided the operating system supports it). Yaskawa has used the following inexpensive model successfully with current generation products and software (SGDH, SMC-2000, SMC-3010, SMC-4000, MP-940, MP-930, MP-920, NS-600, NS-500, NS-300, SigmaWin100, SigmaWin+, YTerm, MotionWorks, MotionWorks+, IndexWorks, NS-XXX): http://www.cablestogo.com/product.asp?cat%5Fid=101&sku=26886 USB to serial adaptors can be purchased from many different vendors, including many PC vendors.
