How To Check The Motor Connection - Danfoss MCO 350 Operating Instructions Manual

4. Synchronisation
Parameter No. 32-67
Maximum track error: Record the value that is to generate "Track error" indication in the display,
if exceeded.
Parameter No. 32-68
Reversing procedure: Record "0" if reversing is allowed, "1" if the slave must always follow the
direction of the master or "2" if reversing is not allowed.
Parameter No. 33-20
Slave marker type: As external marker signals are used, you can set the type of edge triggering
4
of the external marker signal; "2" for a positive edge, "3" for a negative edge.
Parameter No. 33-18
Slave marker interval: Record the interval between two marker signals of the slave. Input of the
interval is in quad counts. If the interval is not known, it can also be determined during the test
run.
Parameter No. 33-19
Master marker type: As external marker signals are used, you can set the type of edge triggering
of the external marker signal here; "2" for a positive edge, "3" for a negative edge.
Parameter No. 33-17
Master marker interval: Record the interval between two marker signals of the master. Input of
the interval is in quad counts. If the interval is not known, it can also be determined during the
test run.
Parameter No. 19-01
Test run speed: Record the speed at which you want to carry out the optimisation run. Record
the speed as a percentage of the speed in Parameter 3280.
Parameter No. 19-02
Test run acceleration: Record the acceleration for the test run in percent of the minimum accel-
eration time. 100% represents the minimum acceleration, 50% is half as fast as minimum
acceleration; the ramp time is thus twice as long.
Parameter No. 19-03
Test run distance: Record the distance (quad counts) for the drive to travel during optimisation.

4.9.3. How to Check the Motor Connection

After programming the above parameters, check the motor connection as follows:
1.
2.

How to test the incremental encoders When you have tested the motor speed direction you test
the incremental encoder connection as follows: 1. Remove all signals to terminals 18-33 and I1-
I10. 2. Select parameter 3450. The current actual position is then displayed, 3. Rotate the slave
drive motor shaft manually in the forward direction. Now the display shows an ascending count
of the slave position. If the count is descending, exchange the slave encoder track A by B and A/
by B/. If there is no counting in the display then check the wiring of the encoder. Follow the same

Remove all signals to terminals 18-33 and I1-I10.
Press [Hand On] button on the LCP.
Set the reference to a low value with the arrow keys (25 to 50 rpm).
Press the [Off] button on the LCP to stop again. If the motor rotates in the wrong direction
then exchange the motor phases.
