Note 1. Connect a surge absorber as close to the servo motor as possible.
2. There is no polarity in electromagnetic brake terminals (B1 and B2).
When fabricating the motor brake cable MR-BKS1CBL-
M-H, refer to section 11.1.4.
(2) When cable length exceeds 10m
When the cable length exceeds 10m, fabricate an extension cable as shown below on the customer side. In
this case, the motor brake cable should be within 2m long.
Refer to section 11.8 for the wire used for the extension cable.

3.12 Grounding
WARNING
Ground the servo amplifier and servo motor securely.
To prevent an electric shock, always connect the protective earth (PE) terminal
(terminal marked
) of the servo amplifier with the protective earth (PE) of the
control box.
The servo amplifier switches the power transistor on-off to supply power to the servo motor. Depending on the
wiring and ground cable routing, the servo amplifier may be affected by the switching noise (due to di/dt and
dv/dt) of the transistor. To prevent such a fault, refer to the following diagram and always ground.
To conform to the EMC Directive, refer to the EMC Installation Guidelines (IB(NA)67310).

Do not connect it directly
to the protective earth of

Note. For 1-phase 200V to 230VAC, connect the power supply to L1 L2 and leave L3 open.
There is no L
3 for 1-phase 100 to 120VAC power supply. Refer to section 1.3 for the power supply specification.
