Operating frequency
command 50[Hz] setting
DRV-0 Set 50[Hz] via potentiometer (V1S).
5 Accel/Decel time setting
DRV-1
DRV-2
Set Accel time to 15[sec] in DRV-1 with decal time to
25[sec] in DRV-2.
6 FX terminal (M7) IO-26
When FX terminal is turned ON, motor rotating in
forward direction starts running at 50[Hz] for 15 [sec].
When FX terminal is turned OFF, motor decelerates to
stop for 25[sec].
7 RX terminal (M8) IO-27
When RX terminal is turned ON, motor rotating in
reverse direction starts running at 50[Hz] for 15[sec].
When RX terminal is turned OFF, motor decelerates to
stop for 25 [sec].
☞ Note: V1S mode enables Forward/Reverse rotation using ±12V power via Analog input command.
Refer to Chapter 6, Parameter description of DRV-00 for details.
☞ Note: Use V1 instead of V1S mode when FWD/REV Run Prevention is active. V1S mode enables the
motor to run both FWD/REV directions.
