Shaft synchronisation configuration
This section explains how to configure the drive as a Master or a Follower in the
Shaft synchronisation mode. A maximum of four Followers can be used in
synchronisation with a Master drive using the CH2 communication link. The Shaft
synchronisation works only when the drive is in EXT2 control.
Checklist for Master/Follower configuration in Shaft synchronisation mode
• Switch off the power for the drives to be configured as Master/Follower and build
the optic fibre link using the communication channel 2. The link should be made in
a ring topology.
• Switch on the power for the drive.
• Select the drive as a Master or a Follower (Par.
Since Shaft synchronisation is used for actual position synchronisation, both the
Master and the Follower should have the pulse encoder is use for speed feedback.
The encoder counts are used to calculate the actual position in mm.
Set the following parameters for encoder configuration:
• Select the encoder module type (Par.
).
• Set the encoder PPR (Par.
• Select the speed measurement mode (Par.
• Select the speed feedback selection as ENCODER (Par.
• Configure the encoder fault (Par.
Set the following parameters in the Master drive.
• Select Synchro control as ON (Par.
• Select the control location as EXT2 (Par.
• Select the drive as a Master (Par.
).
• Select the drive mode as speed (Par.
• Select the number of Followers attached to the drive (Par.
• Select the mode of the Follower drives as speed (Par.
).
• Select the signal to be sent to the Follower as reference 2 as 202 (Speed)
(Par.
).
• Select the CH2 link topology as ring (Par.
• Select Synchro control as ON (Par.
• Select the synchro input (Par.
and Par.
).
• Set the position scaling factor (Par.
).
Set the following parameters in the Follower drive.
• Select the control location as EXT2 (Par.
• Select the drive as a Follower (Par.
• Select the drive mode as speed (Par.
