◆ CW, CCW Input
This signal can be used to receive a positioning pulse
command from a user host motion controller. The user can
select 1-pulse input mode or 2-pulse input mode (refer
to switch No.1, SW1). The input schematic of CW, CCW is
designed for 5V TTL level. When using 5V level as an input
signal, the resistor Rx is not used and connect to the driver
directly. When the level of input signal is more than 5V, Rx
resistor is required. If the resistor is absent, the drive will be
damaged. If the input signal level is 12V, Rx value is 680ohm
and 24V, Rx value is 1.8Kohm.
◆ 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 driving a
motor, one needs to set the signal [OFF]. In normal operations
set the signal [OFF] or 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.
[Caution]
If Alarm Reset input signal still remains [ON], motor will be
Free state. Keep in mind to change [ON]→[OFF] state.

Input Signal
Input signals of the drive are all photocoupler protected.
The signal shows the status of internal photocouplers
[ON: conduction], [OFF: Non-conduction], not displaying
the voltage levels of the signal.
◆ Alarm Output
The Alarm output indicates [OFF] when the drive is in a
normal operation. If a protection mode has been activated, it
goes [ON]. A host controller meeds to detect this signal and
stop sending a motor driving command.
When the drive detects an abnormal operation such as
overload of overcurrent of a motor, it sets the Alarm output to
[ON], flash the Alarm LED, disconnects the power to a motor
and stops the motor, simultaneously.

Output Signal
As the output signal from the drive, there are the
photocoupler outputs (Alarm, Run/Stop). The signal status
operate as [ON : conduction], [OFF : Non-conduction] of
photocoupler not as the voltage level of signal.
◆ Run/Stop Output
Run/Stop Output state is [ON] when motor positioning is
completed. It operates reversely compare to Normal mode,
when you set inverse mode.
