733
Synchronous operation; Program 2:
Accuracy: This parameter specifies that maximum master - slave deviance, this is used
to control the accuracy output (O 3). The accuracy output will only be high (24V) if the
actual master - slave deviance is within this value.
In velocity synchronization (parameter 725 = 0, 3, 6 or 7) the value must be set in RPM
(Rounds Per Minute) in all other modes it must be set in quad counts.
With a negative value in this parameter the synchronizing error (parameter 797) is shown
with a sign otherwise the synchronizing error is unsigned.
734
Synchronous operation; Program 2:
Marker quantity FAULT: Enter when a FAULT signal (O2) must be set. Input the number
of marker pulses, i.e. a setting of 10 means that ACCURACY must be low for 10 marker
pulses before the FAULT signal is set
In position synchronization (parameter 725 = 1 or 4) only the slave marker is used; in
marker synchronization (parameter 725 = 2 or 5) both slave and master marker must be
detected before counting.
735
Synchronous operation; Program 2:
Marker quantity READY: Enter when a READY signal (O1) must be set. Enter the
number of marker pulses, i.e. a setting of 10 means that ACCURACY must be present for
10 marker pulses before the READY signal is set.
In position synchronization (parameter 725 = 1 or 4) only the slave marker is used; in
marker synchronization (parameter 725 = 2 or 5) both slave and master marker must be
detected before counting.
736
Synchronous operation; Program 2:
M-S tolerance speed: Specify here the tolerated speed deviation between master and
slave while the slave during synchronizing. The following apply here:
Slave must catch up: The slave can travel at the maximum permitted speed or at the
speed: master speed + master speed * M-S tolerance speed / 100, whichever of the two is
lowest.
Slave must slow down: The slave travels at the minimum speed:
master speed - master speed * M-S tolerance speed / 100. If the M-S tolerance speed
value is set to 50, the slave will not travel more slowly than half the master speed.
737
Synchronous operation; Program 2:
Gear ratio no.: Select the number of the gear ratio that you want to edit in Parameters
738 - 742.
738
Synchronous operation; Program 2:
Gear ratio numerator: Enter the numerator for the gear ratio selected in Parameter 737.
Ensure that the gear ratio matches the marker ratio.
739
Synchronous operation; Program 2:
Gear ratio denominator: Enter the denominator for the gear ratio selected in Parameter
737. Ensure that the gear ratio matches the marker ratio.
