5-5 Cam Positioner Replacement
H Procedure
Perform the following procedure when replacing the Cam Positioner Unit.
This procedure is applicable when the data (cam programs and parameters) in the original Cam Posi-
tioner is normal and the copy function is operating normally.
If the data has been corrupted or the copy function does not operate normally, use the operation keys on
the new Cam Positioner to input the data and make the settings based on the original cam program data
and parameter settings.
1. Preparation
a) Check that the original Cam Positioner data (cam programs and parameters) is correct. (Refer to
3-5-3 Cam Program Creating and Checking and 3-6 Applied Functions.)
b) Set the CW/CCW setting switch on the new Cam Positioner to the same position as on the origi-
nal Cam Positioner. (Refer to 3-5-2 Initial Settings.)
c) Delete all cam data protects on the new Cam Positioner and then turn OFF the power supply and
turn it ON again to enable this setting. (Refer to 3-6-7 Cam Protect.)
d) Use the copy function and copy the data (cam programs and parameters) from the original Cam
Positioner to the new Cam Positioner. (Refer to 3-6-13 Copy Function.)
e) Check that the data (cam programs and parameters) on the new Cam Positioner is correct. (Re-
fer to 3-5-3 Cam Program Creating and Checking and 3-6 Applied Functions.)
2. Replacement
Replace the Cam Positioner and check the wiring. (Refer to Chapter 2 Design).
3. Compensation
Move the machinery to the origin compensation value position and perform origin compensation.
(Refer to 3-6-4 Origin Compensation and Origin Shift.)
4. Confirmation
Start operation using the new Cam Positioner.
Make adequate checks to ensure that the machinery is operating without any problem.
Adjust the cam programs if necessary. (Refer to 3-5-6 Start Operation, 3-5-7 I/O Monitor Function,
and 3-5-8 Control I/O Signals.)
Note If the machinery cannot be moved to the origin compensation position from when the original Cam
Positioner was set up, perform origin compensation at a different position as outlined below. The
settings can be changed to the same as the original Cam Positioner by re-writing the origin com-
pensation value parameters.
a) Write the origin compensation value for the original Cam Positioner (Function No. b, Parameter
No. 1).
b) After the Cam Positioner has been replaced, move the machinery to the position where origin
compensation will be performed.
c) Set the origin compensation value for that position and turn OFF the power supply and turn it ON
again to enable this setting.
