5.9 Commissioning the brake function
5.9.1 Commissioning brake in space voltage vector control
1. Set P90.04 to 1 to enable the brake function.
2. Set relay brake output. If RO2 is connected to the braking contactor, set P06.04 to 49.
3. If the brake contactor has the feedback function, connect the brake feedback wire to an input
terminal, for example, S3. Then set P05.03 to 75 indicating brake feedback signal. Set P90.31
to 1 to enable brake feedback detection.
4. In lifting application, enable the I/F function, set P04.40 to 1, set P04.41, and set P04.52. In
horizontal moving application, you can choose whether to enable the I/F function.
5. Set P90.12 (Forward brake release current) and P90.13 (Reverse brake release current) to
ensure there is enough torque before the brake is opened.
6. Set the brake timing sequence, including the forward/reverse brake release frequency,
forward/reverse brake closing frequency, delay before forward brake release (T1), delay before
reverse brake release (T5), delay after forward brake release (T2), delay after reverse brake
release (T6), delay before forward brake closing (T3), delay before reverse brake closing (T7),
delay after forward brake closing (T4), and delay after reverse brake closing (T8).
Note: If delay before reverse brake release (T5), delay after reverse brake release (T6), delay before
reverse brake closing (T7), and delay after reverse brake closing (T8) are set to 0, the delay
parameters for forwarding running are used.
7. Perform trial running and check whether the brake timing sequence is correct.
