Note: 1. The built-in regenerative brake resistor is not provided for the MR-E-10AG/20AG.
2. Single-phase 230VAC power supply can be used for MR-E-70AG or servo amplifiers with smaller
capacities. Connect the power cables to L1 and L2 while leaving L3 open.
3. The control circuit connectors (CN1, CN2 and CN3) are safely isolated from main circuit terminals
