WARNING
Personal injuries by hazardous voltage and unregulated move
If you connect the cables with the power supply switched on, it may
cause personal injuries by a hazardous voltage and unregulated move
from the motor.
• Switch off the power supply.
• Make sure that there are no voltage conditions.
• Prevent the energy sources from switching on again.
Before connecting
Connecting sequence
NOTICE
Do not put much stress upon cables or connectors while wiring.
Connecting the encoder cable
NOTICE
Do not touch the encoder pins at the motor with naked hands to avoid
being contaminated.
Connecting the brake cable
NOTICE
Before connecting the brake cable, ensure that the 24 V power supply
has a voltage tolerance of ±10%. Otherwise, the brake cannot work
normally.
NOTE
The motor brake is designed for holding purpose only. Unless
absolutely necessary, do not apply the motor brake as an emergency
stop or deceleration mechanism.

Before connecting the cables, you must
take necessary ESD protection
measures, e.g. wearing an ESD wrist
strap, ESD gloves, and ESD clothes.
The minimum cable bending radiuses
are listed as follows:
Type Radius
Power cable 40 mm
Encoder cable 40 mm
Brake cable 30 mm
The minimum dynamic bending radius
of all cables is 155 mm.
Connect the cables in the following order:
1. Encoder cable (③)
2. Brake cable (②)
3. Power cable (①)
• The absolute encoder cable connector
(①) has three notches.
• The incremental encoder cable
connector (②) has two notches.
• Check the opening time and the
closing time of the holding brake when
starting the servo motor.
• When the brake is powered up, the
servo motor will generate heat even if it
is in the state of servo off. Note that
this is not a fault.
Routing cables
Adjusting cable directions
WARNING
Before adjusting the cables, switch off the power supply. Otherwise, the
motor contains a hazardous voltage and a risk of electrical shock.

Route the power cables and the encoder
cables as shown in the figure, especially
in a humid environment.
1. Loosen the connectors by rotating the
screw rings (①) in the illustrated
direction (②).
2. Adjust the cable directions by rotating
the connectors.
3. Tighten the connectors by rotating the
screw rings inversely.
