The synchronous module realizes a multi-motor synchronous control. Several motors
can be operated
• speed synchronous
• angular synchronous
to a master drive (control drive). The speed relations are individually adjustable. The
control drive must not be controlled. The synchronous module can only be activated
when the inverter is fitted with a second incremental encoder input.
One look onto parameter In.57 answers this question. The following display indications
mean: • „0" synchronous operation possible
• „4" not possible
• „7" synchronous operation possible when the interface is switched to
input (dr.39 = „1").
The synchronous control can be activated/deactivated by way of a programmable
input (see Chapter „Digital Inputs"). When using bus or keyboard the synchronous
control can be activated/deactivated with parameter Sn.0.
Sn.0 Function
0 Synchronous control off
1 Synchronous control on
Writing on this parameter sets the angular difference to zero.
With Sn.1 it is selected between speed and angular syncrhonous control. Furthermore,
the proportional part of the synchronous control is adjusted.
Sn.1 Function
0 Speed synchronous control
1...65535 Angular synchronous control with proportional part
The gear ratio between master speed and slave speed is adjusted in Sn.2. The ratio is
sign-affected; i.e. negative sign means opposite rotation direction.
Slave
Sn.2 = = -20,000...20,000
Master
Three parameters exist for the angular adjustment between master and slave. The
intended position correction angle is entered in Sn.6 (0...360°), intended complete
revolutions are entered in Sn.7 (0...65535). The real correction can then be triggered
by way of a programmable input in the desired direction (see Chapter „Digital Inputs").
The second possibility to start the correction offers Sn.5:
Sn.5 Function
0 No correction
1 Correction in positive direction
2 Correction in negative direction
