Connections – New terminology, important notes
Connections - New terminology, important notes on motor connections
and wiring
This is the new name for the former motor connector in contrast to the
encoder connector.
Now, motor connector stands for a combination of power and encoder
connector. For this, please note the explanations on 1-cable technology below.
With 1-cable technology, the motor power is transmitted together with the
encoder signal in a hybrid cable.
In 2-cable technology, the servomotor has two connectors, one encoder
connector and one power connector. The encoder is connected to the encoder
connector. The load current of the motor is fed through the power connector.
With HIPERFACE DSL®, the encoder signal (DSL) is modulated onto the
power supply line, so only 2 conductors are needed.. These 2 conductors are
routed in one cable in addition to the brake signal and the motor power. The
HIPERFACE DSL® interface can therefore be recognized by the fact that the
motor only has one connector.
NOTICE
Malfunction
Malfunctions of the encoder caused by missing contacts of the pins will
result in malfunctioning of the motor.
Ensure vertical position of the encoder connector. The encoder
connector must not cant.
Please mind correct pin assignment and coding of the encoder
connector.
If there are several codings on the connector, make sure you use
the correct one.
The cable diameter must be designed according to the continuous rated
current of the motor. Please do also observe the ambient conditions, the mode
of installation and the local regulations.
You can either order prefabricated cables from Jetter AG or opt for self-made
cables.
Note on the JL1 motor and some JHN2 motors:
In the order reference, the length of the cables is specified in meters, e.g.
S3-1.00 or S4-1.00 for a cable length of 1.00 m.
