Output signals
Driver output signals are photocoupler/open-collector output (ALARM, END and
TIM.1) and transistor open-collector output (ASG1 and BSG1). 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.

ALARM output
ALARM output remains “ON” when the driver is operating normally, then turns
“OFF” when a protective function is triggered. Detect this ALARM output on the
controller side and cancel the command to operate the actuator thereafter.
Error detection by the driver, such as
overload and overcurrent during actuator
operation, turns the ALARM output
“OFF,” blinks the ALARM LED on the
driver, and simultaneously shuts off the
actuator current to stop actuator operation.
Count the number of the ALARM LED
blinks to identify the particular protective
function that has been triggered. For
details, refer to 8 “Protective functions”
on page 44.

END (Positioning complete) output
END output turns “ON” when actuator movement is complete. Conditions for the
issuance of END output are as follows:
END output is issued when the pulse speed is 500 Hz or less, and the rotor has
positioned within ±0.1° of the commanded position.

Note
The timing of the END output turning “ON” after the pulse stops will vary,
depending on the conditions of the load, the pulse input, and the
speed-filter setting.
