[Skip Frequency 1]
[Skip Frequency 2]
[Skip Frequency 3]
Sets a frequency at which the drive will
not operate. [Skip Frequency 1-3] and
[Skip Frequency Band] must not equal 0.

087 [Skip Freq Band]
Determines the bandwidth around a skip
frequency. [Skip Freq Band] is split,
applying 1/2 above and 1/2 below the
actual skip frequency. The same
bandwidth applies to all skip frequencies.

088 [Speed/Torque Mod]
Selects the torque reference source.
“Zero Torque” (0) - torque command = 0.
“Speed Reg” (1) - drive operates as a
speed regulator.
“Torque Reg” (2) - an external torque
reference is used for the torque
command.

“Min Torq/Spd” (3) - selects the smallest algebraic value to regulate to when the
torque reference and torque generated from the speed regulator are compared.
“Max Torq/Spd” (4) - selects the largest algebraic value when the torque reference
and the torque generated from the speed regulator are compared.
“Sum Torq/Spd” (5) - selects the sum of the torque reference and the torque
generated from the speed regulator.
“Absolute” (6) - selects the smallest absolute algebraic value to regulate to when
the torque reference and torque generated from the speed regulator are
compared.
454 [Rev Speed Limit]
Sets a limit on speed in the negative
direction, when in FVC Vector mode.
Used in bipolar mode only. A value of
zero disables this parameter and uses
[Maximum Speed] for reverse speed limit.
