Configuration
7.3.1
7-40
48XX/49XXSHB0399
Master
Purpose
The master configuration C005 = -52- or -53- is:
( to activate the phase control
which is preconnected to the speed controller
( to configure the drive as master drive for the digital frequency coupling to
generate the master digital frequency for the following drives
The phase control is used to improve the control features of the drive, so that a
drift-free standstill is achieved, e.g. for:
( positioning tasks
( hoists, etc.
The set-value path is selected according to the configurations -1X- and -4X-.
Features
( Either resolver or incremental encoder feedback
( Master with signal conditioning as for the configurations C005 = -1X-, -4X-
( DF output signal is set-value for slave 0 (master drive) and other slaves
( For slava 0 evaluation possibility of the set-value with a factor
(numerator/denominator) as well as gearbox adaptation
(numerator/denominator). Adjustable via LECOM, motor potentiometer or
analog terminal
( External torque limitation possible
( QSP function for the whole drive group
( Ctrl. enable function results in loading of the set-value integrator with the
actual value of slave 0 (set-value = actual value)
( Influence possible via codes for pahse trimming and speed correction (via
LECOM, motor potentiometer, analog terminal or one of the signal sources
under C145)
( Indication "following error limit reached" can be set by a code
( TRIP when reaching the phase controller limit
( Speed limit of slave 0 = 1.8 ¼ C011
( Phase controller influence of 0 (0 = deactivated) adjustable up to 1.00
The master drive consists of the master integrator and the slave 0. Slave 0 is the
first drive at the master frequency.
