Programming Parameters D-25
117
Voltage Loop Error Limit Gain
[PI Err Lim Gain]
This parameter specifies the gain to be applied in
the PI error limiter.
The P115 listing describes what the error limiter
does, and how it is activated.
Parameter Type Sink (Read/Write)
Display Units None
Drive Units Display Units * 8
Factory Default 12.00
Minimum Value 0.00
Maximum Value 4096
Related Parameters P115, P116
118
Voltage Loop Proportional Gain
[Iq Kp Gain]
This parameter specifies the proportional gain that
is applied to the Voltage Loop Error (P142).
The proportional (Kp) gain is adjusted to respond
to a change in load.
Parameter Type Sink (Read/Write)
Display Units None
Drive Units Display Units * 8
Factory Default 15.00 (adjusted by RGU)
Minimum Value 0.00
Maximum Value 8100
Related Parameters P119, P121, P142
The value of this parameter is adjusted by
the RGU. See P121 for more details.
119
Voltage Loop Integral Gain
[Iq Ki Gain]
This parameter specifies the integral gain that is
applied to the Voltage Loop Error (P142). The
integral gain is adjusted to remove any steady
state instabilities. After the gain from this
parameter is applied to P142, the result is stored
in P120.
Parameter Type Sink (Read/Write)
Display Units None
Drive Units Display Units * 8
Factory Default 1500.00 (adjusted by RGU)
Minimum Value 0.00
Maximum Value 8100
Related Parameters P118, P120, P121, P142
The value of this parameter is adjusted by
the RGU.
120
Voltage Loop Integrator Output
[Iq Integ Output]
This parameter displays the integral error
command, which is calculated from the Voltage
Loop Integral Gain (P119) and the Voltage Loop
Error (P142).
Parameter Type Sink (Read/Write)
Display Units % of P11
Drive Units Display Units * 5120/100
Factory Default 0.0
Minimum Value -640.0
Maximum Value 640.0
Related Parameters P119, P121
The value of this parameter, which is displayed
as a percentage of P11 (Rated AC Line Current),
is used to determine the Voltage Loop PI Output
(P121). The listing for P121 shows how this
parameter is used in the PI regulator.
