D-42 Programming Parameters
199
Current Loop Damping
[DSP Damping]
This parameter defines the damping used in the
current loop.
Parameter Type Sink (Read/Write)
Display Units %
Drive Units Display Units * 1
Factory Default 100
Minimum Value 50
Maximum Value 200
Related Parameters P198
200
Iq Reference Rate Limit
[Iq Change Rate]
This parameter defines the rate limit for the Iq
reference. This value is used by the current limiter
to prevent the Iq Reference (P96) from changing
too rapidly.
Parameter Type Sink (Read/Write)
Display Units % of P11
Drive Units Display Units * 1
Factory Default 33.33
Minimum Value 2.44
Maximum Value 366.21
Related Parameters P198
For example, a 575V AC M-code RGU, bydefault,
would not allow the Iq reference to change more than
200A (33.33% of 602A (P11)).
201
Per Unit Internal Capacitance Charge Rate
[Int Charge Rate]
This parameter indicates the charge rate of the
RGU internal capacitance.
To determine the rate, divide P16 (Nominal DC
Bus Voltage) by this value.
Parameter Type Source (Read Only)
Display Units msec
Drive Units Display Units * 1
Factory Default 27
Minimum Value 0.00
Maximum Value 1000
Related Parameters P202
202
Per Unit System Capacitance Charge Rate
[Sys Charge Rate]
This parameter indicates approximate charge rate
for the system capacitance.
To determine the rate, divide P16 (Nominal DC
Bus Voltage) by this value.
Parameter Type Source (Read Only)
Display Units msec
Drive Units Display Units * 1
Factory Default 32
Minimum Value 0.00
Maximum Value 1000
Related Parameters P201
203
External Capacitance
[Ext Capacitance]
This parameter specifies the estimated sum
capacitace of the all the AC units connected to the
DC bus. This value is used to calculate the
proportional and integral gains in the PI regulator
(P118 and P119).
Parameter Type Sink (Read/Write)
Display Units uF/10
Drive Units Display Units * 1
Factory Default 9600
Minimum Value 10
Maximum Value 65000
Related Parameters P202, P204
