Note 1. The built-in regenerative resistor is not provided for the MR-J2S-10CP (1).
2. For 1-phase 230VAC, connect the power supply to L
1
, L
2
and leave L
3
open. Refer to section 1.2 for the power supply
specification. L
3
is not provided for a 1-phase 100 to120VAC power supply.
3. Servo amplifiers MR-J2S-200CP have a cooling fan.
