Operation
Error Retry Function
•Do not come close to the machine when using the error retry function because the machine may abruptly 
start when stopped by an alarm.
•Be sure to confirm the RUN signal is turned off before resetting the alarm because the machine may 
abruptly start.
Non-Stop Function at Momentary Power Interruption
•Do not come close to the machine when selecting restart in the non-stop function at momentary power 
interruption selection (b050) because the machine may abruptly start after the power is turned on.
Operation Stop Command
•Provide a separate emergency stop switch because the STOP key on the Digital Operator is valid only when 
function settings are performed.
•When checking a signal with the main power supply applied, if a signal voltage is erroneously applied to the 
control input terminals, the motor may start abruptly. Be sure to confirm safety before checking a signal.
