50[Hz] freq
command setting
DRV-0 Set freq command 50[Hz] via V1 (potentiometer).
5 Accel/Decel time
DRV-1
DRV-2 Set Accel time to 15 [sec] in DRV-2.
Set Decel time to 25 [sec] in DRV-3.
6 Terminal FX I/O-26
Motor starts to rotate in Forward direction at 50Hz with
Accel time 15 [sec] when FX terminal is turned ON.
Motor decelerates to stop with Decel time 25[sec] when
FX terminal is turned OFF.
7 Terminal RX I/O-27
When RX terminal is turned ON motor starts to
rotate in Reverse direction at 50[Hz] with Accel
time 15 [sec]. When it is OFF, motor decelerates
to stop with Decel time 25 [sec].
