Function:
Test run acceleration: Specify here the acceleration for the
test run as a percentage of the maximum acceleration. 100 %
means that the drive accelerates with the minimum ramp speci-
fied in par. 32-81. 50 % means that the drive only proceeds with
half the acceleration, i.e. the acceleration takes twice as long as
with the minimum ramp specified in par. 32-81.
Synchronous operation; Program 2: Hold function:
If the contact at Terminal 29 is closed, the slave drive is disen-
gaged, i.e. it no longer runs in synchrony with the master.
If "0" is set, the slave drive is brought to the speed set in par.
19-03.
If "1" is set, the actual speed is maintained. While these signals
are present, the current Hold speed can be changed by means
of Inputs 32 and 33.
Function:
Test run distance: Specify the distance for the test run in quad
counts.
Synchronous operation; Program 2:
Hold speed: If Hold function "0" was selected, enter here the
speed as a percentage of the maximum speed (par. 32-80).
Function:
This parameter is used to specify the type of synchronisation
used when optimising the PID controller for synchronisation by
means of the virtual master.
Speed synchronising Select "0" if speed synchronising should be used in synchronous
mode
Position synchronis- Select "1" if position or marker synchronising should be used in
ing synchronous mode.
Synchronous operation; Program 2:
Delta hold speed: Specify the percentage by which the hold
speed is to change when Input 32 or 33 is activated during Hold
mode.
Function:
This parameter is used to trigger automatic calculation of the
optimal value for velocity feed forward (par. 32-65) as well as
PID sample time (par. 32-69), proportional factor (par. 32-60)
and derivative factor (par. 32-61).
