• In addition, make sure there is sufficient strain relief for the motor
power cable as near as possible to the control cabinet outlet of the
motor power cable (8).
Note: Do not remove the shield of the motor cable between ground
bus and device.
If the motor cables are routed to the control cabinet via flange boxes, the
shield is directly connected to the wall of the control cabinet over a large
surface area via the housing of the flange box. Make sure there is
sufficient separate strain relief.
Bad ground connection between motor housing and control cabinet
housing, as well as long motor cables, can require additional routing of a
bonding conductor of a cross section of normally 10 mm² between control
cabinet housing and motor housing.
Note: For cable lengths of more than 50 m the cross section should
be at least 35 mm

.
For kit motors make sure that the connection lines are run in shielded
form or under metal between winding and terminal box, if the terminal box
is not directly mounted on the spindle case.
For linear motors connect the shield of the connection cable between
primary part and terminal box via clips to machine housing or metal shell.
The inner shields of temperature monitor and brake in the motor cable are
connected to the drive controller at one end.
X6, Motor Temperature Monitoring and
Motor Holding Brake
The drive controller is supplied with 24V for the motor holding brake via
the control voltage connection.
DANGER
High electrical voltage! Danger to life, severe
bodily harm by electric shock!
Always operate the drive controller with plugged on
connector, because high voltages can occur at the
connector at the end of the cable (coming from
motor)!
