3.
Set parameter 133 [Inert Adapt BW] = parameter 90 [Spd Reg BW].
4.
Verify that the Lead-Lag filters are off: parameter 93 [SRegFB Filt Gain]
=1 and parameter 95 [SReg Out Filt Gain] =1 to disable the filters.
5.
Enable inertia adaption, parameter 132 [Inert Adapt Sel] bit 0 “Inrtia
Adapt” = 1.
6.
Enable the drive and adjust the bandwidth (BW) for the application but
do not exceed curve 2 shown below. When you adjust the BW, you must
set parameter 90 and parameter 133 to the same BW. You may hear an
unusual high frequency sound which indicates adaption is active.
Speed/Torque Mode Select
Parameter 110 [Speed/TorqueMode] is used to choose the operating mode for
the drive. The drive can be programmed to operate as a velocity regulator, a
torque regulator, or a combination of the two. Refer to the firmware flowchart
shown in
