b38
q-Current Reference(q axis reference current)
Range: -100.0 ~ 100.0 in 0.1
Real time editable q axis reference current compensates Torque Estimate Error.
If Torque estimate offset is bigger than 0
No increase in output frequency even if regeneration is occurred.
This situation could be end with OV Trip.
If so, set b38 to a positive value
If Torque estimation offset smaller than 0
No increase in output frequency even if regeneration is not occurred.
Output Frequency could be increased to Max. Freq (Reference Fre
b34) and end up with E02 (OVS Fail)
If so, set b38 to a negative value

b39
Filter Bandwidth (q axis LPF coefficient)
Range: 0 ~ 1000 milliseconds in 1 mSec
Real time editable Iq feedback Low Pass Filter time constant
If output Frequency is not stable,
Increase b39 value
Recommended Value as a function of (b39); (b37) value should be set accordingly
Not set over 50

Overvoltage Suppression (wDec Mode)
0: Disabled
1: Enabled
Select to enable the Voltage Suppression Control function.

b41
Limit Time (wRegen Time)
Range: 0.0 ~ 1000 Sec in 0.1 Sec
Real time editable OVS control fail check time. If PID output is saturated to Maximum
OVS output Frequency (b34) during this time period, VFD will stop and E02 will be
occurred.
