Parameter Descriptions
INERTIA SCALE
PREF: 134.24
Default: 0
Range: See below
Set the motor’s inertia scale.
Enumerated Value : Inertia Scale
0 : Kg*m²
1 : Kg*cm²
2 : g*m²
●
STAND CURRENT
PREF: 134.26
Default: 10.6
Range: 0.00 to
4096.00 A
Permanent current at standstill: if not known, set to the same value as PERM CURRENT at low speed
●
THERMAL TIME CST
PREF: 134.27
Default: 224.80
Range: 0.00 to 10000.00 s
Copper Therma
l Time constant(s). If not known, set to 300s.
CUR LOOP BWDTH
PREF: 134.28
Default: 600
Range: 100 to 1500 Hz
This parameter defines the current loop bandwidth. The value will automatically generate the proportional gain of the PI
corrector of the curren
t 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
PREF: 134.29
Default: 150
Range:
5 to 600 Hz
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
PREF: 134.30
Default: 3.
0
Range: 1.0 to 10000.0
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.
