Execution of optimization runs
8
The drive must be in operating state o7.0 or o7.1 (enter SHUTDOWN!).
8.1
Select one of the following optimization runs in key parameter P051:
8.2
P051 = 25
P051 = 26
P051 = 27
P051 = 28
P051 = 29
The SIMOREG converter switches to operating state o7.4 for several seconds and then to o7.0
8.3
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.
As soon as the converter reaches operating status <o1.0 (RUN), the optimization run is
8.4
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.

Optimization run for precontrol and current controller for armature and field
Speed controller optimization run
can be preceded by selection of the degree of dynamic response of the speed
control loop with P236, where lower values produce a softer controller setting.
Optimization run for field weakening
Optimization run for compensation of friction moment and moment of inertia
Speed controller optimization run for drives with oscillating mechanical system.
Optimization run for precontrol and current controller for armature and field
(process lasts approximately 40s)
The current controller optimization run may be executed without a mechanical
load coupled to the motor; it may be necessary to lock the rotor.
The following parameters are set automatically: P110, P111, P112, P155, P156,
P255, P256, P826.
CAUTION
Permanent-field motors (and motors with an extremely high residual flux) must be
mechanically locked during this optimization run.
CAUTION
In order to avoid rotation in the case of separately excited motors with a very high
field circuit time constant, the motor field current must be zero before starting this
optimization run. The value 1 (11, 21) must therefore be set at P082 instead of 3
(13, 23) for the duration of this optimization run. The standstill field P257 is to be
set to 0.0 percent if P082 = 2 (12, 22).
