Rotation/Movement Direction Is Reversed - Panasonic FPG Series Technical Manual

FP∑ Positioning Unit Operation if an Error Occurs

15.3.4 Rotation/Movement Direction is Reversed

Example of reversed rotation/movement direction:
Solution 1
Make sure the wiring between the positioning unit and the driver has been correctly connected.
Point to check:
Make sure the CW/CCW output or the Pulse/Sign output has been connected to the pertinent input on
the driver side.
-> "Connection of pulse output signal" (Refer to page 3-9.)
Solution 2
Check to make sure the control codes in the shared memory match the specifications for the position
command values.
Point to check:
The settings for the increment "relative value control" and the absolute "absolute value control" are
specified through the control codes in the program.
-> Increment and Absolute (Refer to page 4-13.)
Solution 3
If the settings for the position command data have been designed with the plus (+) and minus ( - )
directions reversed, change the direction of rotation, using the mode settings witches on the back of the
unit.
-> "Pulse output mode" (Refer to page 4-2.)
