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 L
1
and L
2
while leaving L
3
open.
3. The control circuit connectors (CN1, CN2 and CN3) are safely isolated from main circuit terminals
(L
