6.4.18.3Holding brake

¾Series / 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)

¾Parameterize 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): P1310, P1311

b)SLVC (P1300 =20): P1610, P1611

¾It 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.

¾It 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.

¾The brake closing / opening times can be taken from the appropriate manual. The following typical values have been taken from Motor Catalog M11 2003/2004, Page 2/51:

NOTE

The following must apply when controlling the brake relay via a digital output: P0731 = 52.C (= 52.12) (refer to Section 6.4.4 "Digital outputs (DOUT)").
