Commissioning a motor holding brake
Precondition
The motor holding brake is connected to the converter.
WARNING
Load can fall if the motor holding brake function is incorrectly set
For applications with a suspended load, such as cranes and elevators, there is a danger to life
if the "Motor holding brake" function is not completely set or is incorrectly set.
• When commissioning the motor holding brake function, secure any suspended loads, e.g.
by applying the following measures:
– Lower the load down to the 󹪞oor.
– Secure the dangerous area so that nobody can inadvertently enter it.
• Set the motor holding brake function according to the following description.
• After commissioning, check that the motor holding brake and the motor control function
reliably.
Procedure
1. Set p1215 = 1.
The motor holding brake function is enabled.
2. Check the magnetizing time p0346.
The magnetizing time must be greater than zero. The converter assigns the magnetizing time
when it is being commissioned.
3. Find out the mechanical opening and closing times from the technical data of the motor
holding brake.
– Depending on the brake size, brake opening times lie between 25 ms and 500 ms.
– Depending on the brake size, brake closing times lie between 15 ms and 300 ms.
