Check the operation of the forward rotation limit switch.
During operation in the forward rotation direction (at step 8), turn off the forward rotation limit switch
1 (X010), and confirm that the operation in the forward rotation direction is stopped.
The LED indicator lamps and the current value register (D8341, D8340) will change to the same
statuses as the stop statuses described in step 8.
In addition, the "Instruction execution abnormal end" flag (M8329) will turn on.

Check the operation in the reverse rotation direction.
Check the output indicator lamp (LED lamp) and the current value register to monitor the operation.
The status of the LED indicator lamp and the value indicated in the current value register depend
on the pulse output destination or rotation direction set by the positioning instruction. However, if
the pulse output destination or the rotation direction is changed for the test program, carefully read
the status of the output indicator lamp (LED lamp) and the value indicated in the current value
register to monitor the change.
1. Operation in reverse rotation direction
Turn on the reverse rotation (JOG-) switch (X013), and verify that the operation is performed in the
reverse rotation direction. For this check, set the other inputs as follows:
Input signal
1) LED indicator lamp check
Check the LED indicator lamps of the PLC or the display module to check whether the outputs are turned
on. The status of each output should be as shown in the following table:
If the transistor outputs of
the main unit are used
If the high-speed output
special adapter is used
*1.
2) Current value register (D8341, D8340) check
Monitor the current value register (D8341, D8340) of the FX
programming tool, and confirm that the value is being reduced.
