Parameter Descriptions
INERTIA
PREF: 134.23 Default: 0.0010 Range: 0.0000 to 100.0000
Set the motor’s inertia. The units for this parameter are set by the INERTIA SCALE parameter.
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 1024.00 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 Thermal 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 current loop. The proportional gain is calculated based on the "L" motor parameter.
Modif

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.
