WARNING
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
brake cable at both ends.
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
range.
NOTICE
Faulty brake function due to inadmissible wear
Inadmissible wear means that the braking function can no longer be guaranteed.
• Comply with the predefined Emergency Stop characteristics.
• Avoid repeated brief acceleration of the motor against a holding brake that is still closed.
Consider the operating times of the brakes and the relays in the drive control and
enable.
Note
The total length of the power cables (motor feeder cables and DC link cables) must not
exceed the values listed in Chapter
Combination options, Line Modules with line reactors
and line f
ilters (Page 135).
Note
The motor brake must be connected via connector X11. It is not permitted to directly connect
the cable BR
- to the electronics ground M.
