Phase trimming

The phase trimming can be changed and displayed under C256.
( Code C256 can be accessed via analog terminal, motor potentiometer,
one of the signal sources under C145, keypad or LECOM.
( Thus, the rotor position can be adjusted by a maximum of –4 revolutions.
Negative values stand for an adjustment to the left and positive values for
an adjustment to the right.
Resolution: 1 incr. ref. to an encoder type 8192 incr./rev.
Following error limit
The following error limit can be set under C255 in increments. The setting range
is: 0...536.750.000 increments. The maximum value of the phase difference is
65.521 revolutions and does not depend on the encoder.
Hysteresis: 10 increments.
When the following error limit is reached, a signal is generated which is evaluted
via the "monitorings". Thus, the priority (TRIP, message or warning) can be
evaluated according to the user's requirements.
With switching controller enable, the phase difference is set to zero.
With an activated phase controller, phase synchronism and drift-free
syncoronous running with the controller set-value (the same as set-value of other
controllers) can be achieved.
By means of gearbox factors (C032 and C033) in the corresponding drive it is
possible to compensate for mechanically asymmetric operation of the system
(e.g. different gearboxes). This means, that phase synchronis at the gearbox
output shafts can be implemented.
