Holding brake
Series / commissioning for hazardous loads
− lower the load to the floor
− when replacing the frequency inverter, prevent (inhibit) the frequency
inverter from controlling the motor holding brake (MHB)
− secure the load or inhibit the motor holding brake control (so that the brake
cannot be controlled) and then – and only then – carry-out quick
commissioning / parameter download using the PC-based tool (e.g.
STARTER, AOP)
Parameterize the weight equalization for hoisting gear applications
− magnetizing time P0346 greater than zero
− min. frequency P1080 should approximately correspond to the motor slip
r0330 (P1080 ≈ r0330)
− adapt the voltage boost to the load
a) V/f (P1300 = 0 ...3):
b) SLVC (P1300 =20):
It is not sufficient to just select the status signal r0052 bit 12 "motor holding
brake active" in P0731 – P0733. In order to activate the motor holding brake, in
addition, parameter P1215 must be set to 1.
It is not permissible to use the motor holding brake as operating brake. The
reason for this is that the brake is generally only dimensioned/designed for a
limited number of emergency braking operations.
The brake closing / opening times can be taken from the appropriate manual.
The following typical values have been taken from Motor Catalog M11

NOTE
The following must apply when controlling the brake relay via a digital output: P0731 = 52.C (= 52.12)
(refer to Section 3.5.7.4 "Digital output (DOUT)").
