Control Mode Selection (A1-02) - Omron V1000 Guía Rápida De Referencia

5 Start Up
Power On
Before turning on the power supply,
• Make sure all wires are connected properly.
• Make sure no screws, loose wire ends or tools are left in the drive.
• After turning the power on, the drive mode display should appear and no fault or
alarm should be displayed.

Control Mode Selection (A1-02)

There are three control modes available. Select the control mode that best suits the
applications the drive will control.

for Energy Saving
Never touch the motor until the Auto-Tuning is finished. Even thought the motor may not
be rotating when Auto-Tuning, voltage is still applied to the motor during the tuning
process.

Main Applications
Perform when setting the drive to operate in Open
Loop Vector control. The motor must be able to rotate
without load during the tuning process in order to
achieve a high accuracy.
Perform in V/f control if the motor cable is long or if the
cable has been changed.
Perform when using Energy Saving or Speed
Search.The motor must be able to rotate without load
in order to achieve a high tuning accuracy.
