Start several homing procedures for both drives, as described in step 9.
Set the home position offsets with machine data MD4 = U501.04 by
trial and error starting with value "0" until the desired starting position
for the synchronization is reached (a reminder: a value of 3600 LU in
MD4 means one motor revolution). With the 2-axis demonstration pack,
the start position is as follows on the two flywheels:
Fig. 9-49 Start position for synchronization with 2-axis demonstration pack
In this start position, you will see the LED through the drilled holes on
both wheels.
When you have configured a suitable MD4 setting on both drives,
please proceed as follows in order to test the synchronization via
SIMOLINK:
a) Set 0 V on the setpoint potentiometer of drive 2; this corresponds to
a velocity setpoint of 0 %.
b) Perform the homing procedure for both drives, in order to establish
the start position in the sketch above (→ with the 2-axis
demonstration pack, the LED beam must be visible through both
flywheels).
c) Cancel the start command for both drives (START = 0). Both drives
are now in the start position, position-controlled.
d) Start the synchronization on the slave drive (drive 1) with
START = 1. It does not yet start to move, because the virtual master
on drive 2 has not yet been enabled, and defines a path setpoint of
"0".
e) Start the master drive with START = 1 (drive 2). This activates the
enable signal for the virtual master axis.
f) You can now start both drives with the potentiometer and modify the
speed (0...10 V equals 0...MD23 equals 2778 min
-1
in r230 [360]).
g) With all speeds, the LED beam should be visible through both
flywheels if the synchronization is operating correctly.
Application example 2 is now complete. When you have worked
through all the steps in application example 2, you will have a sound
overview of the "positioning" and "synchronization" functions and their
connection and commissioning. You will have also received an
introduction to the documentation available in an easy-to-understand
example. The further steps required to commission your own
customized application should now be much easier.
