2.11 Troubleshooting
Should problems arise with the Synchro, first check that all drives function correctly without synchronization being
activated.
Problem Possible cause Checking
Synchro functions normally, V2.4.10.1
(master) does not show position error,
but between hooks there comes
position error. System does not register position error
between hooks because P2.2.2. Nominal
Speed in one or more drives is not correct or
accurate enough. Check P2.4.4 Nominal speed in all drives.
One or more drives are vibrating
especially after acceleration or
deceleration. Too high gain level. Speed correction is
overshooting. Reduce P2.4.6. SystemBus Synchro gains
value in master drive.
Position error between hooks,
especially after acceleration,
deceleration or stopping. Different ramp times or stop function. Check that Ramp time and Stop method
parameters P2.1.10, P2.1.11 and P2.2.20
have similar value in every drive.
