9. Control signal Input/Output Description
Input signals of the drive are all photocoupler inputs. The signal shows the status of in-
ternal photocouplers [ON: conduction], [OFF: Non-conduction], not displaying the voltage
levels of the signal.
◆
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 of 2-pulse input mode. The input schematic
of CW, CCW is designed for 5V TTL level. When using 5V level as an input signal, the resistor
Rx is used and connect to the drive directly. When the level of input signal is more than 5V,
have to add Rx. If this resistor is absent, the inner schematic can be broken. In input signal
level is 12V case, Rx value is 680ohm and in 24V case, 1.8Kohm is suitable for Rx value.
◆
Motor Free Input
This input can be used only to adjust the position by manually moving the motor shaft from
the load-side. By setting the signal [ON], the drive cuts off the power supply to the motor.
Then, one can manually adjust output position. When setting the signal back to [OFF], the
drive resumes the power supply to the motor and recovers the holding torque. When driv-
ing a motor, one needs to set the signal [OFF]. In normal operations set the signal [OFF] of
disconnect a wire to the signal.
◆
Alarm Reset Input
When a protection mode has been activated, a signal to this Alarm Reset input cancels the
Alarm output. By setting the alarm reset input signal [ON], cancel Alarm output. Before cancel
the Alarm output, have to remove the source of alarm.
9.1 Input Signal
[Caution] If Alarm Reset input signal still remains [ON], motor will be Free state. Keep in mind to change
[ON]→[OFF] state. It operates reversely compare to Normal mode, when you set inverse mode.
