DRV-0 Set freq command 50[Hz] via V1 (potentiometer).
4 Accel/Decel time
DRV-1
DRV-2
Set Accel time to 10 [sec] in DRV-1.
Set Decel time to 20 [sec] in DRV-2.
5 Terminal FX (M7) I/O-26
Motor starts to rotate in Forward direction at 50Hz
with Accel time 10 [sec] when FX terminal is turned
ON.
Motor decelerates to stop with Decel time 20[sec]
when FX terminal is turned OFF.
6 Terminal RX (M8) I/O-27
When RX terminal is turned ON motor starts to rotate
in Reverse direction at 50[Hz] with Accel time 10
[sec]. When it is OFF, motor decelerates to stop with
Decel time 20 [sec].
