Note 1. When having the servo amplifier comply with the IEC/EN/UL/CSA standard, refer to appendix 4.
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.
