68 SYNC REF MOD

Synchronisation reference modification settings that are used to select between
absolute or relative synchronisation, to set an electrical gear ratio between the
synchronisation reference and the drive positioning system, and to filter the
reference.

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 mode
• shows the position reference in
synchron control mode.
