NOTE
1 See Chapter 4 in the Servo Amplifier αi series
Descriptions for details of how to combine the power
supply module, servo amplifier modules, and spindle
amplifier modules.
2 A magnetic contactor, AC reactor, and circuit
breakers are always required.
3 To protect the unit from surge currents caused by
lightning, connect surge absorbers between lines,
and between the lines and ground, at the power inlet
of the power magnetics cabinet. See APPENDIX A in
the Servo Amplifier αi series Descriptions
(B-65282EN) for details.
