I/O Signal Circuit
The I/O signal circuit can be switched between the sink mode and
source mode using the sink/source select switch on the brake
pack. The factory setting is the sink mode.

✽1 Turn on CW operation input, CCW operation input, and brake release input after turning
on AC power.
The motor does not operate if they are input ahead of AC power.
The ALARM indicator will light and ALARM output will switch to "OFF."
✽2 The brake release input becomes ALARM-RESET input when the ALARM output is OFF.
✽3 Only for electromagnetic brake motors.
✽4 The induction motor will not accommodate instantaneous forward/reverse switching.

CW Operation Input
Turning the CW operation signal to "ON" causes the motor's
output shaft to turn in the CW direction. Turning it to "OFF"
triggers an instantaneous stop.
CCW Operation Input
Turning the CCW operation signal to "ON" causes the motor's
output shaft to turn in the CCW direction. Turning it to "OFF"
triggers an instantaneous stop.
If both the CW and CCW operation signals are simultaneously
turned to "ON," the CW operation signal will take priority.
Therefore, the wiring must be changed with an induction motor
having four lead wires.
Brake Release Input [ALARM-RESET Input]
Functions as a brake release input during normal operation, and
as an ALARM-RESET input when the ALARM output is OFF.
When normal: [Brake Release Input]
Turning the brake release signal to "ON" disables both the
electronic brake and electromagnetic brake. When the CW and
CCW operation signals are turned to "OFF," the motor operates
via inertial force before coming to a natural stop. When the motor
is stationary, the electromagnetic brake is not activated, so the
motor's output shaft can be moved freely.
Turning the brake release signal to "OFF" (or leaving the signal
unconnected) and turning both CW and CCW operation signals
to "OFF" will activate the electronic brake and electromagnetic
brake, bringing the motor to an instantaneous stop. Once the
motor stops, the electronic brake will release automatically.
However, the electromagnetic brake will continue to operate and
hold the load.
When ALARM output is OFF: [ALARM-RESET Input]
When ALARM output is turned OFF, turn all input signals "OFF"
and input 0.5 seconds or more for ALARM-RESET input.
Wait at least 0.5 seconds after turning the ALARM-RESET input
OFF before restarting operation.

It is also possible to deactivate the alarm by turning off the power
and turning it on again. Turn off the DC or AC power, and turn all
input signals "OFF" before turning on the power again.
