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.
Default:
Min/Max:
Units:
0.0 Hz
0.0/30.0 Hz
0.1 Hz

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.
454 [Rev Speed Limit]
Sets a limit on speed in the negative direction.
A value of zero disables this parameter and uses
[Min Speed] for minimum speed.

ATTENTI ON: The speed of the drive could reach P82 [Maximum
Speed] + P83 [Overspeed Limit] to meet required torque when
any of the torque modes have been selected. Equipment
damage and/or personal injury can result.
