PI Limit = 25.02 (Max Out Freq )- OutFreq ; Internally calculated
Meaning of 25.02 is changed from Max Add Freq to Max Out Freq
 25.01 OVS selection
 0: Disable ----- Initial value
 1: Enable
Select to enable the Voltage Suppression Control function.
 25.02 Maximum OVS output frequency
 Range: 0.0 Hz ~ 300.0 Hz in 0.01 Hz
 Initial value: 20.00 Hz
Real time editable a maximum frequency limit for OVS function
 Related Parameters:
 25.03 OVS P gain
 Range: 0 ~ 10000 in 1
 Initial value: 1000
Real time editable P gain for OVS PID loop
 PIOut = err * Kp
 Hz = err(%) * Kp * scalefactor(50 * 1e-6)
Example
 err 10%, Kp = 1000
 PIOut = 0.5Hz
 Recommended Value in test bench
 1000 or less than 5000
 25.04 OVS I gain
