How To Check The Motor Connection; How To Test The Incremental Encoders - Danfoss MCO 350 Operating Instructions Manual

4. Synchronisation
Parameter No. 32-10
Record "No action" for clockwise rotation of both master and slave. Record "User units reversed"
if the slave is to run in the opposite direction.
Parameter No. 32-80
Record maximum RPM measured at the slave encoder.
Parameter No. 32-81
Minimum ramp: Set the time in ms for the slave drive to accelerate from standstill to maximum
speed (par 3280). The value is important, as this setting highly affects the control accuracy!
4
Parameter No. 32-82
Ramp type: Record "0" for linear ramp and "1" for s-ramp. Note: S-ramp requires higher accel-
eration torque
Parameter No. 32-67
Maximum track error: Record the value that is to generate "Track error" indication in the display,
if exceeded. Input is in quad counts.
Parameter No. 32-68
Reversing behaviour: 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.
The settings are automatically saved.

4.7.4. How to Check the Motor Connection

When the above parameters have been programmed, check the motor connection as
follows:

4.7.5. How to Test the Incremental Encoders

After testing the motor speed direction, test the incremental encoder connection as
follows:
1.
2.
3.
4.
5.
Follow the same procedure when testing the master encoder but use parameter 34-52 for read-
out of the master position. Remember to push [Auto On] to return to normal control.

Remove all signals to terminals 18-33 and I1-I10
Press [Hand On] button on the LCP.
Set the reference tor a low value with the arrow kkeys (25 to 50 rpm).
Please note that the motor may now turn
Press the [Off] button on the LCP to stop again. If the motor rotates in the wrong direction
then exchange the motor phases.
Remove all signals to terminals 18-33 and I1-I10.
Select parameter 3450. The current actual position is then displayed.
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.
