photocouplers.
[ON: conduction], [OFF: Non-conduction], not displaying the voltage levels of the signal.
CW(Pin:1, 2), CCW(Pin:3, 4)
◆ ◆ CW, CCW Input
This signal can be used to receive a positioning pulse command from a user-side host
motion controller. A user can select 1-pulse input mode or 2-pulse input mode.
◆ ◆ Motor Free Input
This input can be used only to adjust the position by manually moving the motor shaft
from the Ioad-side. By setting the signal[ON], the driver cuts off the power supply to the
motor. Then, one can manually adjust output position. When setting the signal back
to[OFF], the driver resumes the power supply to the motor and recovers the holding
torque. When driving a motor, one needs to set the signal[OFF]. In normal operations set
the signal [OFF] or disconnect a wire to the signal.
It operates reversely compare to Normal mode, when you set Inverse mode.
