Min Max Description
0.0 20.0 If Filter Currents is set to "Filter
CTs", set this parameter to the out‐
put filter caacitor, i.e. admittance
value, as a ration of the base out‐
put amittance of the drive: typical‐
ly 10 %. If Filter Currents Source is
set to "Output CTs" set this param‐
eter to the output cable parasitic
capacitance as a ratio of the base
output admittance of the drive.
Admittance is the inverse of impe‐
dance.*
0.0 50.0 Output cable resistance value as a
ratio of the base output impe‐
dance of the drive.*
0.0 50.0 Output cable inductance is used
for long runs of cable. Enter in
percent of drive base impedance.
-5.00 5.00 Control the gain for damping oscil‐
lations due to output filter. Use a
positive constant, typically 0.5,
with cable length less than 30000
feet. Use a negative constant, typi‐
call -0.5, for long cable lengths.
