Optional data
Description
Motor rated magnetization
current/short-circuit current
Maximum motor speed
Maximum motor current
PE spindle, reluctance torque
constant
Motor moment of inertia
Ratio between the total and
motor moment of inertia
Motor weight
Motor stator resistance, cold
Motor stator inductance Lq
Motor stator inductance Ld
Comments
If this value is not known, then a
"0" can also be entered. Using
this value, the stator leakage
inductance can be more
precisely calculated (p0356,
p0357).
