ALM-RST input
The ALM-RST input is a signal to reset an alarm status. (The alarm will be reset at the ON edge of the input.)
To reset an alarm, turn the operation input signal OFF, and remove the cause of the alarm before turning the ALM-RST
input ON. In the case of the 3-wire mode, when both the START/STOP input and RUN/BRAKE input are being ON, the
ALM-RST input is disabled. (In the case of the 2-wire mode, when either the FWD input or the REV input is being ON, the
ALM-RST input is disabled.) If the alarm cannot be reset with the ALM-RST input, once turned o the power supply and
turn on again.

TL input
The TL input is a signal to switch whether to enable or disable the torque limiting function. (Factory setting ON)
When the TL input is turned ON, the torque limiting function is enabled.
The maximum value of the motor output torque is limited based on the set torque limiting value.
When the TL input is turned OFF, the torque limiting function is disabled, and the maximum value of the motor output
torque will be the peak torque.
