Note 1. The built-in regenerative resistor is not provided for the MR-E-10AG-QW003/MR-E-20AG-QW003.
2. Single-phase 230VAC power supply can be used for MR-E-70AG-QW003 or servo amplifiers with smaller capacities. Connect the
power cables to L
1
and L
2
while leaving L
3
open. Refer to section 15.1.3 for the power supply specification.
3. The control circuit connectors (CN1, CN2 and CN3) are safely isolated from main circuit terminals (L
1
, L
2
, L
3
, U, V, W, P, C and D).
4. Servo amplifiers MR-E-200AG-QW003 have a cooling fan.
