A191 [Skip Freq Band 2] Related Parameter(s): A190
Determines the bandwidth around A190 [Skip Frequency 2]. A191 [Skip Freq Band 2] 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 Hz
Min/Max: 0.0/30.0 Hz
Display: 0.1 Hz

A192 [Skip Frequency 3] Related Parameter(s): A193
Sets the frequency at which the drive will not operate.
A setting of 0 disables this parameter.
Values Default: 0 Hz
Min/Max: 0/320 Hz
Display: 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.
