5.1.1.5 Commissioning master/slave holding brake synchronization control (for winches)
In master/slave mode, if you need to perform brake release/closing for both the master and slave,
refer to the following procedure:
1. Set P90.04 to 1 on both the master and slave to enable the holding brake function for the master
and slave.
2. Set P28.00=1 for the master and P28.00=2 for the slave, and set P28.02 to select a
master/slave mode.
3. Set P28.14 to 0x11 to enable the master/slave holding brake synchronization function for the
master and slave.
4. Set relay holding brake output for the master and slave. If RO1 is connected to the holding brake
contactor, set P06.03 to 49.
5. Set the delay before forward brake closing and delay before reverse brake closing to 0 (that is,
P90.24=0 and P90.25=0) for the master and slave.
6. For other holding brake parameters, see sections 5.1.1.3 Commissioning brake in torque control
to 5.1.3.3 Space voltage vector control application commissioning procedure. For other
master/slave control parameters, see 5.5 Master/slave control.
7. Perform trial run and check whether the holding brake timing is correct.
Note:

In master/slave mode, you need to set the delay before forward brake closing and delay before
reverse brake closing to 0; otherwise the master and slave will not synchronize.

In situations where the master and slave are rigidly connected, the holding brake can be
controlled only by the master, and the master/slave holding brake synchronization control can be
disabled (for the master and slave, P28.14=0x00), while the holding brake logic of the slave is not
