Commissioning the control logic of a motor holding brake
The following applications require special settings of the motor holding brake. In these
cases, the motor holding brake control may only be commissioned by experienced
personnel:
• All applications that involve moving and transporting people
• Hoisting gear
• Elevators
• Cranes
1. Before commissioning, secure any dangerous loads (e.g. loads on inclined conveyor
belts)
2. Suppress the motor holding brake control, e.g. by disconnecting the control cables
3. When opening the motor holding brake, ensure that a torque is established that prevents
the load from briefly dropping.
– Check the magnetizing time P0346; the magnetizing time is pre-assigned when
– For V/f operation (P1300 = 0 to 3), set the boost parameters P1310, P1311.
4. Parameterize the opening and closing times of the motor holding brake
It is extremely important that electromechanical braking is controlled with the correct
timing (brake release time, brake closing time, release time) to protect the brakes against
long-term damage. The exact values can be found in the technical data of the connected
brake. Typical values:
– Brake release times are between 35 ms and 500 ms
– Brake closing times are between 15 ms and 300 ms
5. Restore the motor holding brake control
– The mechanical brake on the motor is connected to the Inverter through the motor
– To activate the motor holding brake, parameter P1215 must be set to 1.
When a motor with a built-in holding brake is commissioned, a "clicking" sound in the motor
indicates that the brake has been properly released.
