Field Regulator [102]
P0173 – Variation Rate of the Field Reference (If*)
Adjustable Range:
0 to 3000 ms
Factory Setting:
200 ms
Properties:
Groups of
01 PARAMETER GROUPS
Access via HMI:
26 REGULATORS
........
102 Field Regulator
........
Description:
It defines the time for the field current reference (If* signal) to vary from zero to the maximum value.
P0175 – Proportional Gain of the Field Regulator
Adjustable Range:
0.00 to 9.99
Factory Setting:
0.50
P0176 – Integral Gain of the Field Regulator
Adjustable Range:
0.00 to 3.99
Factory Setting:
0.25
Properties:
Groups of
01 PARAMETER GROUPS
Access via HMI:
26 REGULATORS
........
102 Field Regulator
........
Description:
Gains of the field current regulator, which must be set so as to optimize the dynamic response of the field loop.
In order to set these gains properly, follow the procedures described in sections 6.4.4.
P0177 – Minimum Field Current
Adjustable Range:
0.0 to 50.0 A
Factory Setting:
1.0 A
Properties:
Groups of
01 PARAMETER GROUPS
Access via HMI:
26 REGULATORS
........
102 Field Regulator
........
Description:
Minimum limit for the field current. It must be set with the value informed on the motor nameplate for the
maximum speed condition (for motors that operate in the field weakening area).
It also defines the value for actuation of the Field Loss protection (F074), which will be activated when the
current measured by the converter falls below 50 % of the value in P0177.
NOTE!
Is not possible adjust the value of parameter P0177 over the configured value on the parameter
P0404 (Nominal Field Current).
P0178 – Field Economy Current
Adjustable Range:
0.0 to 50.0 A
Factory Setting:
0.6 A
Properties:
Groups of
01 PARAMETER GROUPS
Access via HMI:
26 REGULATORS
........
102 Field Regulator
........
Description:
Value of the current applied to the motor field when the converter is Disabled or with Faults present.
