4.9 Brake control parameter(Group P60)
The closed loop control is enabled, while the breaking operation of the brake depends on the conditions.
When the forward operation output torque is larger than the setting of P60.00 (relative to motor rated
torque), and the time delay of P60.02 elapses, the breaking command will be output. When the reverse
operation output torque is larger than the setting of P60.01 (relative to motor rated torque), and the time
delay of P60.02 elapses, the breaking command will be output.
When the frequency is reduced to P60.03 (brake close frequency) upon shutdown, and the brake close
time delay (P60.04) elapses, the brake signal will be output. The two function codes together complete
the brake control.
Closed-loop control valid: To ensure smooth lifting control, the time for staying at the starting 0.00Hz and
stopping 0.00Hz are added.
To ensure smooth lifting control, the low-speed running frequency (P60.07) and the time for staying at low
speed (P60.08) are added. The default value for the open-loop is 3Hz, for the closed loop is 1Hz.
In the closed-loop control before of the brake is released, pre-torque (P60.09) is added gradually by
pre-torque delay P60.10, while monitoring the encoder feedback signal, if the monitoring frequency
exceeds P61.05 set value, it is considered that mechanical brake can not reach the appropriate brake
torque, report fault Er.FbL.
Open-loop control is valid.
Uplink firstly adopt P60.11 + P26.07 as the set frequency to start running, and then determine whether
the output torque reaches P60.13 and the output frequency reaches P60.11; downlink firstly adopt
