Lubricating the oil seal
NOTICE
Do not use a motor with an oil seal submerged in oil.
The oil seal (①) should be used with
sufficient lubricant oil splashed on it.
4 Electrical installation
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.

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 static bending radii for
the cables are listed as follows:
Type Radius
Power cable 5 x outer diameter
Encoder cable 5 x outer diameter
Brake cable 5 x outer diameter
The minimum dynamic bending radii
of the cables are all 155 mm.
Connect the cables in the following
order:
1. Encoder cable (③)
2. Brake cable (②)
3. Power cable (①)

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.
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.

• 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.
Route the power cables and the encoder
cables as shown in the figure, especially
in a humid environment.
Low inertia motors of SH50 + high inertia
motors with straight connectors:
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.
High inertia motors with angular
connectors:
Adjust the cable directions by rotating
the connectors.
