Danger of death due to high touch voltages for brake cables
For motor cables with integrated brake cable, when the motor is operated, the motor can
charge the brake cable up to hazardous voltage levels. Coming into contact with the
conductors or the shield of the brake cable can result in death or serious injury.
• Use motor cables with separate, shielded brake cables and connect the shield of the
NOTICE
Premature wear of the motor holding brake when operated outside its permissible voltage
range
Operating the motor holding brake outside its permissible voltage range at the motor
connection will damage the brake.
• Ensure that the motor holding brake is only operated within its permissible voltage
NOTICE
Faulty brake function due to inadmissible wear
Inadmissible wear means that the braking function can no longer be guaranteed.
• Comply with the defined Emergency Stop characteristics.
• Avoid repeated brief acceleration of the motor against a holding brake that is still closed.
Note
The motor brake must be connected via connector X1/X2. The BR- cable must not be
connected directly to electronics ground (M).
Note
Shielding
Attach the motor cable shield to the shield connection plate on the Motor Module using the
shield connection clamp supplied in the terminal kit. You can find more detailed information
in Chapters "Motor connector" (Page 67) and "Shielding and routing cables" (Page 106).
