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
3. The control circuit connectors (CN1, CN2 and CN3) are safely isolated from main circuit terminals (L
4. Servo amplifiers MR-E-200AG-QW003 have a cooling fan.
