Parameter for
Description
vector control
p1240 = 1
Vdc controller configuration(Factory setting: 1)
1: Vdc controller is enabled
r1242
Vdc_max control activation level
DC link voltage value above which the Vdc_max control is acti-
vated
p1243
Vdc_max control dynamic factor (factory setting: 100 %)
Scaling control parameters p1290, p1291 and p1292
---
Vdc_max controller time threshold
Setting the monitoring time of the Vdc_max controller.
p1250
Vdc_max control proportional gain (factory setting: 1)
p1251
Vdc_max control integral time (factory setting p1291: 40 ms,
p1251: 0 ms)
p1252
Vdc_max control rate time (factory setting p1292: 10 ms, p1252:
0 ms)
p1254
Vdc_max control automatic ON level sensing(Factory setting,
dependent on the Power Module)
Automatically sense switch-on levels of the Vdc_max control.
0: Automatic detection disabled
1: Automatic detection enabled
p0210
Unit supply voltage
If p1254 or p1294 = 0, the inverter uses this parameter to calcu-
late the switch-in thresholds of the Vdc_max control.
Set this parameter to the actual value of the input voltage.
