Execution of optimization runs
8.1 The drive must be in operating state o7.0 or o7.1 (enter SHUTDOWN!).
8.2 Select one of the following optimization runs in key parameter P051:
P051 = 25 Optimization run for precontrol and current controller for armature and field
P051 = 26 Speed controller optimization run
P051 = 27 Optimization run for field weakening
P051 = 28 Optimization run for compensation of friction moment and moment of inertia
8.3 The SIMOREG converter switches to operating state o7.4 for several seconds and then to o7.0
or o7.1 and waits for the input of SWITCH-ON and OPERATING ENABLE..
Enter the commands SWITCH-ON and OPERATING ENABLE.
The flashing of the decimal point in the operational status display on the PMU (simple operator
control panel) indicates that an optimization run will be performed after the switch-on command.
If the switch-on command is not given within 30 s, this waiting status is terminated and fault
message F052 displayed.
8.4 As soon as the converter reaches operating status <o1.0 (RUN), the optimization run is
executed.
An activity display appears on the PMU, consisting of two 2-digit numbers, separated by a bar
that moves up and down. These two numbers indicate (for SIEMENS personnel) the current
status of the optimization run.
P051 = 25 Optimization run for precontrol and current controller for armature and field
(process lasts approximately 40s)
The following parameters are set automatically: P110, P111, P112, P155, P156,
P255, P256, P826.
NOTE
Permanent-field motors (and motors with an extremely high remanence) must be
mechanically locked during this optimization run.
WARNING
The set current limits are not effective during the current controller
optimization run. 75% of the rated motor armature current flows for
approximately 0.7s. Furthermore, individual current spikes of
approximately 120% of the motor rated armature current are
generated.
