Connector
Description
Internal signed actual current value (armature), averaged over one firing
K0114
cycle
Current controller actual value (armature)
K0115
Absolute value of internal actual current (armature)
K0116
K0117
Internal signed actual current value (armature)
K0118
Current controller setpoint (armature)
K0119
Current controller setpoint (armature) before absolute-value generation
Current setpoint (armature) before reduced gear stressing
K0120
Precontrol output (armature)
K0121
EMF which is applied as an input value for the armature precontrol
K0122
(generated from K0123 or K0124 depending on P162, filtered acc. to P163)
EMF= U a −I a *R a −L a *di a /dt, where the measured armature voltage is applied
K0123
as U a
(Note: K0287 is the result of PT1 filtering with 10ms)
EMF= U a −I a *R a −L a *di a /dt, where the armature voltage calculated from the
K0124
delay angle, measured armature conduction interval and mean line voltage
is applied as U a . If this calculation cannot be made or is insufficiently
accurate (e.g. with a conduction angle < 10°, average armature current value
< 2 % in r072.002), K0124 assumes the value set in K0123.
K0125
Armature current setpoint after reduced gearbox stressing or current setpoint
integrator
Current limitation
K0131
Lowest positive current limit (armature)
Highest negative current limit (armature)
K0132
K0133
Current setpoint (armature) before limitation (incl. additional setpoint)
K0134
Current setpoint (armature) before torque limitation
Torque limitation, speed limiting controller
Normalization of torque connectors:
An armature current corresponding to 100% of the converter rated DC current (r072.002) with a motor flux (K0290) corresponding to
100 % of the rated motor field current (P102) produces a torque of 100%.
Note:
Whether connectors K0140, K0141, K0145 and K0147 act as the torque setpoint or the current setpoint depends on P170 (setting
determines which quantity is divided by motor flux).
Speed limiting controller, active torque limit 1
