Range: 0 ~ 10000 Sec in 1 Sec
Initial value: 100 Sec
Real time editable I gain for OVS PID loop
PIOut = ∫(err * Ki)
Hz += err(%) * Ki * scalefactor(50 *1e-6), dT = 1ms
Example ( Integration Time to 10Hz on Error)
err 10%, Ki = 1000
Time to 10Hz on 10% Error = 20ms
err 10%, Ki = 100
Time to 10Hz on 10% Error = 200ms
err 10%, Ki = 10
Time to 10Hz on 10% Error = 2000ms
Recommended Value in test bench
100 or less than 500
25.05 OVS D gain
Range: 0 ~ 10000 Sec in 1Sec
Initial value: 0 Sec
Real time editable D gain for OVS PID loop. Its value depends on
'25.07' (Filter bandwidth)
;
filter bandwidth. Thus, if
'25.07' (Filter bandwidth)
is not changed, no need to change
'25.05' (OVS D gain)
value. Most application, this value should not be set over 3000
Recommended Value as a function of
'25.07' (Filter bandwidth)
If
'25.07'
< 10
'25.05'
: 0 ~ 500
If
'25.07'
< 30
'25.05'
: 500 ~ 1000
If
'25.07'
< 50
'25.05'
: 1000 ~ 1500
25.06 q-Current reference
Range: -100.0 ~ 100.0 in 0.1
Initial value: 0.0
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
'25.06' (q-Current reference)
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 Frequency +
'25.02' (Maximum OVS output frequency)
) and end up with ovFS (OVS
control Fail)
If so, set
'25.06' (q-Current reference)
to a negative value
