Programming Parameters D-29
137
Wn, Bus Feedback Filter Bandwidth
[Leadlag Freq, Wn]
This parameter specifies bandwidth for the bus
feedback filter. This filters the feedback using the
following formula:
Parameter Type Sink (Read/Write)
Display Units R/S (rad/sec)
Drive Units Display Units * 1
Factory Default 1000
Minimum Value 0
Maximum Value 32767
Related Parameters P138, P140, P141
138
Kn, Bus Feedback Filter Gain
[Leadlag Gain, Kn]
This parameter specifies gain for the bus feedback
filter. This filters the feedback using the formula
listed in P137.
Parameter Type Sink (Read/Write)
Display Units None
Drive Units Display Units * 1
Factory Default 0.63
Minimum Value 0.00
Maximum Value 5.00
Related Parameters P137, P140, P141

Bus Voltage Input Select
[Volt Mode Sel]
This parameter selects the input used for the bus
voltage feedback.
Parameter Type Sink (Read/Write)
Display Units None
Drive Units Display Units * 1
Factory Default 0
Minimum Value 0
Maximum Value 2
Related Parameters P38, P60, P61, P143
Value Description
0 DSP Averaged Selects P61 (DSP Average Bus Voltage) as the input used for the Scaled Bus Feedback (P143).
1 DSP Channel Selects P60 (DSP DC Bus Voltage) as the input used for the Scaled Bus Feedback (P143).
2 Host Channel Selects P38 (A/D Converter 2 Input) as the input used for the Scaled Bus Feedback (P143). P38 provides a sample
from the DC bus.
140
Bus Prefiltered Feedback
[Bus Prefil Fbk]
This parameter displays the bus feedback value
before it is filtered (by the formula shown in the
P138 listing) and passed to P141 (Bus Feedback).
Parameter Type Sink (Read Only)
Display Units Volt
Drive Units Display Units * 4096/P16
Factory Default 0
Minimum Value 0
Maximum Value 1.5 x P16
Related Parameters P137, P138, P141, P143, P218, P219
P219 (Feedback Select) can select feedback
from the DC bus (P143), or can select a
simulated feedback (P218) as the input for
this parameter.
