9.12 Application: Tandem winder
9.13.1 Digital frequency output
The digital frequency output is required e.g. for a master Slave
coupling (two motors are connected by friction to one winder shaft).
For master-Slave couplings it is important that, in case of Speed
reduction of the master, e.g. due to the current limiting function
Imax,, the Slave Passes the same field frequency to the motor as the
master.
A frequency Signal which is proportional to the field frequency tan
be supplied to terminal X9. To activate this function the value 200
must be set under CO08. The corresponding setting of pulse/Hz
tan be calibrated under CO30 (see chapter 5.6).
9.12.2 Information about the Slave drive
The Slave drive tan either be equipped with the series Software or
the variant Software. Only the master drive must be equipped with
the variant Software VOO9 which is valid for the dancer-Position
control and thus the control of the field frequency.
Caution!
The acceleration and deceleration times (CO1 2EO13) of the Slave
must be 0 sec in the tandem winder application. Otherwise, the
shaft will undergo torsion when accelerating or decelerating the
drive.
