Parameter Descriptions
INERTIA SCALE
Set the motor's inertia scale.
Enumerated Value : Inertia Scale
● STAND CURRENT
Permanent current at standstill: if not known, set to the same value as PERM CURRENT at low speed
● THERMAL TIME CST
Copper Thermal Time constant(s). If not known, set to 300s.
CUR LOOP BWDTH
This parameter defines the current loop bandwidth. The value will automatically generate the proportional gain of the PI
corrector of the current loop. The proportional gain is calculated based on the "L" motor parameter.
Modifying the CUR LOOP BWDTH value could induce instability. Please contact our application engineer if you need to
change it.
INTEGRAL FREQ
This parameter defines the frequency of the Integral action of the PI corrector of the current loop.
Modifying this value could induce instability. Please contact our application engineer if you need to change it.
KE REF
Gain used when the drive is in the flux weakening control.
Modifying the KE REF value could induce instability. Please contact our application engineer if you need to change it.
