P149 - Compensation of the DC Link Voltage
Adjustable
Range:
0 = Inactive
1 = Active
Factory
Setting:
0
Properties: cfg
Description:
It enables the use of Compensation of the DC link.
P150 - Type DC V/f Link Regulator
Adjustable
Range:
0 = Hold_Ud and Decel_LC
1 = Accel_Ud and Decel_LC
2 = Hold_Ud and Hold_LC
3 = Accel_Ud and Hold_LC Factory
Setting:
0
Properties: cfg
Description:
P150 configures the behavior of the ramp for the limitation functions of the DC Link Voltage and Current Limitation.
In those cases, the ramp ignores the reference and takes an action of accelerating (accel), decelerating (decel)
or freezing (hold) the normal path of the ramp. That occurs because of the limit pre-defined in P151 and P135
for the DC Link (Ud) Limitation and for Current (LC) Limitation, respectively.
P151 - DC Link Regulation Level
Adjustable
Range:
348 to 460 V
Factory
Setting:
According to
Table 11.1 on
page 11-4
Properties:
Description:
Voltage level to activate the DC link voltage regulation.
