Description
p1294 p1254
Vdc_max control automatic sensing ON level
(factory setting
p1294: 0, factory setting p1254: PM330/PM240 = 1, PM230 = 0)
Activates or deactivates automatic detection of the switch-on
levels of the Vdc_max control.
0: Automatic detection disabled
1: Automatic detection enabled
p0210 p0210
Unit supply voltage
If p1254 or p1294 = 0, the inverter uses this parameter to
calculate the switch-in thresholds of the Vdc_max control.
Set this parameter to the actual value of the input voltage.
