A193 [Skip Freq Band 3] Related Parameter(s): A192
Determines the bandwidth around A192 [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.
Values Default: 0.0 Hz
Min/Max: 0.0/30.0 Hz
Display: 0.1 Hz

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)
(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): d310-d317
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
