Description of Parameters
620 CL: Load drooping 234567 (P1.6.12.4, P1.6.15.4)
The drooping function enables speed drop as a function of load. This parameter sets
that amount corresponding to the nominal torque of the motor. See Page A-3.
621 CL: Startup torque 234567 (P1.6.12.11, P1.6.15.11)
Chooses the startup torque.
Torque Memory is used in crane applications. Startup torque FWD/REV can be used in
other applications to help the speed controller. See Page A-3.

3 Torq.Fwd/Rev
626 CL: Acceleration compensation 234567 (P1.6.12.5, P1.6.15.5)
Sets the inertia compensation to improve speed response during acceleration and
deceleration. The time is defined as acceleration time to nominal speed with nominal
torque. This parameter is also active in advanced open loop mode.
627 CL: Magnetizing current at start 234567 (P1.6.12.7, P1.6.15.7)
628 CL: Magnetizing time at start 234567 (P1.6.12.8, P1.6.15.8)
Sets the rise time of magnetizing current.
631 Identification 23456 (P1.6.13, P1.6.16)
With this parameter, the drive will identify the motor and adjust tuning parameters to
improve starting torque and closed loop current control. See Chapter 6 of the 9000X
User Manual.
0 No Action
1 OL V/F Ratio-ID No Run; the drive is run at zero speed to identify the
stator motor parameters.
2 OL V/F + Boost; same as ID No Run and then turns on V/Hz Boost.
3 (MultiPurpose APP, SPX Only) ID With Run; performs an ID No Run, and
then runs the motor at 2/3 rated frequency to identify the motor no load
current and motor saturation curve. Motor must be unloaded for an
accurate ID Run.
633 CL: Start-up torque, forward 234567 (P1.6.13.5, P1.6.16.5)
Sets the start-up torque for forward direction if selected with parameter P1.6.12.11.
634 CL: Start-up torque, reverse 234567 (P1.6.13.2, P1.6.16.2)
Sets the start-up torque for reverse direction if selected with parameter P1.6.12.11.
