Firmware block:
SYNC REF MOD
(68)
This block
• selects the source for the synchron
reference chain
• defines the gear ratio and selects a
scaling factor for the ratio (in
synchron control the position
reference is first multiplied with the
defined gear ratio and then with the
defined gear scaling factor)
• defines the synchron speed
reference filter time
• defines the maximum position
difference between the unfiltered
and filtered synchron speed
reference
• selects the synchronisation of the
follower drive in synchron control
mode
• shows the position reference in
synchron control mode.
