A193 [Skip Freq Band 3]
Related Parameter(s):
Determines the bandwidth around
[Skip Frequency 3]. A193 [Skip Freq Band 3] is split applying
1/2 above and 1/2 below the actual skip frequency.
A setting of 0.0 disables this parameter.

A194 [Compensation]
Enables/disables correction options that may improve problems with motor instability.
Options
0 “Disabled”
1 “Electrical” (Default)
(1)
Some drive/motor combinations have inherent instabilities
which are exhibited as non-sinusodial motor currents. This
setting attempts to correct this condition.
2 “Mechanical”
Some motor/load combinations have mechanical resonances
which can be excited by the drive current regulator. This
setting slows down the current regulator response and
attempts to correct this condition.
3 “Both”
(1)
Use “Dead Time Compensation” algorithm to minimize flat spots in motor current waveforms. Use
this solution also to achieve motor stability.
A195 [Reset Meters]
Related Parameter(s):
-
Resets the marker that indicates Fault Times and Energy usage.
Options
0 “Ready/Idle” (Default)
1 “Reset MWh”
Also resets kWh marker.
2 “Reset Time”
min, hr, and x10hr
