Ec.27 adjusts the mode of the simulation channel. If channel 2 is adjusted with Ec.20
to incremental encoder output, then the mode in CH2 becomes effective with Ec.27
(Ec.27 source => CH2 useless). Otherwise the adjustments refer to a third pure
simulation channel (e.g. channel 2 15-poles).
When adjusting Ec.27 Bit 0...1 = actual value, then channel 2 may not be occupied,
since the internal encoder counter is used for the generation of the zero signal.
These parameter exists only at F5-S. The system position of the attached resolver
system is adjusted (factory setting).
With this parameter it is possible to adjust the controller to a not aligned motor. If the
system position of the motor is unknown an automatic trimming can carried out.
Before starting with the adjustment, the direction of rotation must be checked. The
speed display (ru.9) must be positive in the case of clockwise rotation by hand. If that
is not the case, the direction of rotation can be exchanged with Ec.6 as described.
• enter motor data
• the connected motor must be able to rotate freely
• open control release
• enter Ec.2/12 = 2206
• close control release
The motor is excited now with its rated current.
If the direction of rotation of the connected motor is not correct or two motor phases
are exchanged, E.EnC is triggered.
For resolver sytems the signal SIN+ and SIN- must be exchanged.
If the system postion displayed in Ec.2/12 no longer changes the alignment is
completed.
• open control release
If motors with aligned encoder systems are used, the value determined by the automatic
alignment can be entered directly in Ec.2/12.
