FIG 7-19 Phase controller
Conditions
Configuration C005 = -52-, -53-, -62-, -63- or -72-
Special features
With the configurations C005 = -12-, -13-, -42- or -43-, the activation of the
phase controller (C254 > 0)during quick stop (QSP)ensures a drift-free standstill.
In continuous operation, the controller is not effective.
The difference calculated from set and actual phase is led to the phase controller
which works as proportional controller. It’s influence can be set under C254.
C254 = 0 means the complete disconnection of the phase controller from the
control path.
Setting range of C254 = 0.00 to 1.00. With C254 = 1.00 and 1 increment control
difference, the phase controller changes the speed set-value by 0.186 rpm.
Phase controller limit
Stop!
When the phase controller limit is reached and the monitoring is switched off, the
sign at the phase controller output may change. By switching controller enable,
the phase difference is set to zero.
The phase controller limit is fixed to a phase difference of 65531 revolutions. If
this phase difference is exceeded, the phase controller can no longer correct the
set phase. When the phase controller limit is reached, a TRIP P13 is generated.
The fault message can be evaluated in its priority.
