	Is an AC input reactor needed with the Single Phase Converter? Posted Date: 09/12/2017 Answer: The Single Phase Converter is a low-harmonic (10% iTHD), active front end for a variable frequency drive. Adding an AC input reactor is not recommended and will provide negligible harmonic improvements.

	In the MP940 controller, how are the FLASH and COPY switches used? Posted Date: 05/21/2001 Answer: When an MP940 program is executed, it runs from RAM memory, and variables (or registers) reside in RAM. Without a battery, this memory will naturally decay and lose information over time, so Yaskawa recommends that a battery is attached to the MP940 to maintain the data in RAM. An alternate method of preserving the program data and register data is to store it in the built-in flash memory of the amplifier. The entire contents of RAM can be saved to Flash using either MotionWorks or MotionWorks+. To retrieve the data from Flash, simply set the dip switches on the front of the MP940 unit. Operation note: Upon application of control power with ONLY the "RUN" switch on, the controller will use the program and registers that are currently resident in RAM. WIthout a battery, the RAM memory is subject to loss, and could result in an A.E0 or A.9F alarm. With the "Flash" switch on during power up, the program will be copied from Flash to RAM for runtime. With the "Copy" switch on, the variable (register) data will be copied from Flash to RAM for runtime. Flash: The "flash" switch copies the ladder programs from Flash to RAM on power-up. The data registers, however, are not copied. Copy: The "copy" switch copies the global variables ('M' registers) from Flash to RAM. The values of these switches are checked during power-up, therefore power must be cycled after turning the switches ON. If the MP940 does not have a battery, both switches should be left on all the time. If variables (registers) are changed on a constant basis (such as from an HMI), and need to be retained, then a battery will be necessary.

	In some pumping systems the motor speed is normally about 80% of rated motor speed. However, periodic purging of the pumping system requires the pump to go to full speed for a while, then return to normal. How is this done with the V7 Drive? Posted Date: 10/27/2005 Answer: The easiest way is to use the Jog Reference input, S7 to toggle between the normal speed reference and the 'Jog Frequency' (n032). Set parameter n032 to 100% frequency. Now when the Jog Reference input is energized the drive will accelerate to 100% speed. When the Jog Reference is released, the drive will return to normal speed. Note: Earlier versions of the V7 Drive were named GPD 315/V7, GPD 315 or VS Mini V7.

	In SigmaWin+ Trace what is the difference between Position Error and Position Amplifier Error? Posted Date: 11/30/2010 Answer: The Position Error trace is the difference between commanded position reference from the controller and the feedback position, while the Position Amplifier Error is the difference between the position command after the model following adjustments and the feedback position.

	In SigmaWin+ Trace, what is the difference between position error, position amplifier error, and motor-load position error? Posted Date: 05/23/2018 Answer: Position error is the difference between the position reference value and the actual position. Position amplifier error is the difference between the position reference value and the actual position after electronic gear conversion. Motor-load position error is the difference between the feedback position of the motor encoder and the feedback load position of the external encoder for fully-closed loop control.

	In order to identify the parameter causing the OPE alarm, one goes to monitor U1-18. On the Z1000 Bypass cabinet, the parameter states "Z0-00". What does this mean? Posted Date: 10/21/2013 Answer: The Z1000 bypass is not able to show all parameters when communicating through the bypass control board, and Z0-00 is displayed when the information given by the bypass control board is incomplete. Please connect the digital operator to the drive and go to U1-18. The parameter will be shown only when connected to the drive. For additional information, please refer to the manual SIEPYAIZ1B01.

	In MotionWorks IEC Pro, what is the difference between a 'zipped' and a 'sealed' project? Posted Date: 07/03/2013 Answer: There are three ways to save a MotionWorks IEC Pro project: 1. The normal method of saving a project is saving it as a standard project (project.mwt). This saves the project in a readily useable format, with the main project file called *.mwt and an associated folder with all code, graphical elements, set up files, etc . In this format, the code can be edited and debugged readily, however, it is difficult to share the project with others in this format. 2. When a project is to be archived and / or shared with others, create a zipped project (project.zwt). This format compresses the project, as well as optionally including user and firmware libraries, front-end (compiled) code and graphical page layouts (see the help file in MotionWorks IEC Pro for more information about these options). Before a zwt file it can be used, it must be unzipped using MotionWorks IEC Pro. This will uncompress the project into the .mwt format. 3. In MotionWorks IEC Pro 2.3.0 and higher, a project can be saved as a sealed project (project.zws). This is similar to a zipped project but protects the integrity of the code. A sealed project becomes read only, and allows the programmer to share the project source code with an end user or service technician without fear that the code will be inadvertently changed. Assuming the Sealed Project version is the same as the code originally downloaded to the machine, the user can debug a machine without compiling and downloading. Tools such as Logic Analyzer and debug mode, and read/write recipes and watch window are available. The user CANNOT modify the project, and the project cannot be re-compiled (see the help file in MotionWorks IEC Pro for the complete list of benefits and restrictions of a sealed project).

	In MotionWorks IEC Hardware Configuration, why are the Mechatrolink III axes displayed as offline when the ServoPacks are powered up with no alarms? Posted Date: 06/05/2015 Answer: If the controller had any problems discovering the ServoPacks when powering up, the ServoPacks may have to be power cycled. The first remedy to try is power cycle the entire system. For the axes to be displayed as online, they must have been powered up before the MWiec controller. Since the controller takes several seconds to complete its power up phase, powering the entire system at the same time is fine. If there is no Startup configuration, or if any of the hardware may have been changed, check the switch settings for all ServoPacks. All Mechatrolink III devices must be configured for 48 byte packets and the assigned node numbers must be unique and in the range of 3 to 64. Next, confirm that all cables are connected correctly. The MP3000iec controllers and ServoPacks have LEDs in the Mechatrolink connector that are lit when a cable is plugged into the socket that is connected to an active node. When all devices are powered, check the LED status in all connectors. Finally, if there is a Startup configuration and all the hardware is configured correctly, check the configured response times. The configured response times must be very close to the measured response times. Values that are slightly lower, or much higher than the measured response times may cause the controller not to connect to these nodes. The measured response times can be viewed by allowing doing the following: 1) Using the web server, delete the Startup Configuration 2) Set the MWiec controller to self configure (CNFG DIP switch must be ON) 3) Using the Hardware Configuration, connect with a new project, or connect with an existing project and use the discovered configuration. 4) Refer to the Mechatrolink-III node in the Hardware Configuration to view the measured response times.

	In MotionWorks IEC Hardware Configuration, how can a configured axis be moved from one node number to another?
