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 leakage inductance
Lq
Motor stator leakage inductance
Ld
Note
If this value is not known, "0" can
also be entered. This value
enables the stator leakage
inductance (p0356, p0357) to be
calculated more accurately.
