Note 1. In order for the servo amplifier to comply with the UL/CSA standard, see the applicable "Servo Amplifier Instruction Manual".
2. Use a magnetic contactor with an operation delay time (interval between current being applied to the coil until closure of
contacts) of 80 ms or less.
3. S-N18 can be used when auxiliary contact is not required.
Select a molded-case circuit breaker with a short shut-off time to prevent smoking
and fire from the servo amplifier.
Always use one molded-case circuit breaker and one magnetic contactor with one
servo amplifier.
