Output signals
The signal state represents the “ON: Carrying current” or “OFF: Not carrying current” state of the internal
photocoupler rather than the voltage level of the signal.

SPEED-OUT output
30 pulses are output with each revolution of the motor output shaft synchronously with the motor operation.
The pulse width of output pulse signals is 0.2 ms. You can use the SPEED-OUT output to calculate the motor speed.

To display/monitor the speed of the motor output shaft or reduced speed of the gearhead output shaft, connect the
accessory digital speed indicator
SDM496
(sold separately). Refer to p.51 for details.

ALARM-OUT1 output
When the driver’s protective function actuates, the ALARM-OUT1 output turns OFF and the ALARM LED blinks
(normally closed).
The motor coasts to a stop in the case of a standard type. When the motor is an electromagnetic brake type, the motor
stops instantaneously and the electromagnetic brake is actuated to hold the shaft in position.
To reset an alarm, turn both the FWD input and REV input OFF, remove the cause of the alarm, and then turn the
ALARM-RESET input ON (and keep it ON for 10 ms or more). The ALARM-RESET input will not be received if
the FWD input or REV input is ON.
If the alarm cannot be reset with the ALARM-RESET input, turn off the power, wait for at least 30 seconds, and then
turn the power back on.

The electromagnetic brake locks the moment an alarm generates. The electromagnetic brake can be set to lock after a free-
run stop of the motor using the
OPX-2A
or

Using a controller with a built-in clamp diode
If a controller with a built-in clamp diode is used, a leakage
path may form and cause the motor to operate even when the
controller power is off, as long as the driver power is on. Since
the power capacity of the controller is different from that of the
driver, the motor may operate when the controller and driver
powers are turned on or off simultaneously.
When powering down, turn off the driver power rst, followed
by the controller power.
When powering up, turn on the controller power rst, followed
by the driver power.
