About providing for ALARM output
When the driver-protection function is triggered, the lineard motor stops as the current is turned off. The lineard
motor loses its holding ability, which in a vertical-travel application may cause the load to fall. The user must set a
controller sequence that will cut off the power to the electromagnetic brake and hold the load in position upon
detecting an “OFF” ALARM output.

*1 After the power has been shut off, wait at least 10 seconds before turning the power back on.
*2 To input the DIR.-A or DIR.-B signal pulse, wait at least 0.1 second after clearing the ALARM output.
*3 The turning of END output to “ON” does not necessarily mean the motor has stopped. Provide enough of a time
delay for a halt, which will vary, depending on the acceleration/deceleration rates and load condition. The time for
END output to turn “ON” after the pulse signal stops will vary, depending on the pulse signal input condition and
speed-filter setting condition.
*4 Detect TIM. output only at a pulse speed of 500 Hz or less. No accurate detection is possible at a speed over 500 Hz.
*5 Turning C.OFF input ON shuts off the lineard motor current, at which time the lineard motor’s rack loses its holding
ability. It also clears the value on the deviation counter.
