P7.12 PID preset frequency
Range:
The ac drive model of no more than
4kW: 0.00～650.0Hz【0.00Hz】
The ac drive model of no less than
5.5kW: 0.00～400.0Hz【0.00Hz】
P7.13 Hold time of PID Preset frequency
Range: 0.0～3600s 【0.0s】
Note:
◆This function can make the PID regulation enter stable state quickly.
◆When the PID operation is start, the frequency will ramp up to the PID preset
frequency (P7.12) within the Acc time, and then the
ac drive will start PID operation
after operating at the PID preset frequency for a certain time (defined by P7.13).

Tips:
You can disable the function by setting the PID preset frequency (P7.12) to 0.
P7.14 Analog closed loop measuring range
Range: 1.0～999.9【100.0】
Note:
◆This parameter is treated as a benchmark of analog PID feed and feedback. In addition,
it must match the actual measuring range.
P7.15 Enable dormancy
Range: 0,1【0】
0: Disable 1: Enable
Tips:
There is no standby function when the speed PID feed is used.
P7.16 Dormancy delay time
Range: 0～999s【120s】
P7.17 Dormancy threshold
Range: 0～Frequency upper limit【20.00Hz】
P7.18 Awakening threshold
Range: 0.0～999.9【3.0】
