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 lineard motor
thereafter.
Error detection by the driver, such as overload and overcurrent during lineard motor operation, turns the ALARM
output “OFF,” blinks the ALARM LED on the driver, and simultaneously shuts off the lineard motor current to stop
motor 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 p.37
END (Positioning complete) output
END output turns ON when lineard motor’s rack movement is complete.
END output turns ON when the pulse speed is 500 Hz or less, and the rotor has positioned within ±1.8° of the
commanded position.

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.
TIM. (Timing) output
TIM. output are available in two types: transistor open-collector output (TIM.1/GND) and line-driver output (TIM.2+/
TIM.2−). Use either one to suit the input system of the positioning controller.
The use of TIM. output requires separate 5 VDC or 24 VDC power supply.
TIM. output turns “ON” whenever the motor’s output shaft rotates 7.2°.

•
Always connect either 5 VDC or 24 VDC as the power for TIM. output. Do not connect 5 VDC and
24 VDC power supplies at the same time, as it may damage the driver and power supplies.
•
The TIM. output should be detected at a pulse speed of 500 Hz or below. If the pulse speed is
higher than 500 Hz, the TIM. output time will decrease and the signal may not be detected.
•
To switch the resolution using the ×10 input, do so when the TIM. output is ON and the lineard
motor is at standstill. If the resolution is switched in any other condition, the TIM. signal may not be
output even after the rack has traveled by the specified amount.
