Q : What are the differences and triggering conditions between P11.01 and P11.16 on GD28 drive?
A: What are the differences and triggering conditions between P11.01 (Frequency drop at transient power-off) and P11.16 (Automatic frequency-reduction during voltage drop) on GD28 drive?
Solution:
When P11.01 is enabled, in the event of a short-term bus voltage drop, the VFD will reduce its output frequency to brake the motor, in motor brake status, it will generate energy to maintain the bus voltage.
When P11.16 is enabled, when the bus voltage decreases, the VFD's output frequency will decrease synchronously. This applies to both VF and vector modes.
