2.2 List of parameters
Description: Sets the rated armature voltage as indicated on the motor's nameplate.
This parameter is used, for example, to specify the trigger point in field weakening operation.
Note: If a significant voltage drop is to be expected at the motor's supply line when the motor is at rated current (e.g. very
long motor cable), a value increased by this voltage drop should be set at p50101.
Description: Sets the rated excitation current as indicated on the motor's nameplate.
Note: If p50102 = 0.00 A, the drive cannot be switched on and put into operation.
Description: Sets the minimum excitation current for the motor.
Description: Sets speed n1 according to the motor's nameplate for "speed-dependent current limitation".
The characteristic for "speed-dependent current limitation" is defined by 2 pairs of values (p50104/p50105,
p50106/p50107).
This parameter sets speed n1 for the first pair of values (p50104/p50105).
Dependency: Refer to: p50105, p50106, p50107, p50108, p50109
Note: The following condition applies:
p50104 <= p50106 (n1 <= n2)
