DANGER
Dangerous movements! Danger to personnel
from falling or slipping axes!
⇒ The standard motor holding brake provided or an
external motor holding brake controlled directly by
the drive controller are not sufficient on their own to
guarantee the safety of personnel!
⇒ Personnel safety must be achieved using higher-
ranking, fail-safe procedures:
Dangerous areas should be blocked off with
protective fences or grids.
Secure vertical axes against falling or slipping after
switching off the motor power by, for example:
- mechanically locking the vertical axis
- providing external brake/catching/clamping
mechanisms
- adequately counterbalancing the axis
Power consumption levels for the holding rate can be found in the project
planning documents for AC motors.
The holding brake for AC motors is not designed as a service brake. After
approximately 20,000 motor revolutions against the closed brake disc it is
worn out.
The drive controller assumes the control of the motor holding brake.
