Check the operation in the forward 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 forward rotation direction
Turn on the forward rotation (JOG+) switch (X012), and verify that the operation is performed in the
forward rotation direction. For this check, set the other inputs as follows:
Input signal
X010
X011
X013
1) LED indicator lamp check
Check the LED indicator lamps of the PLC or the display module to see whether or not 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. The output LED is kept ON in the FX
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 increased.
2. Stop of operation
Turn off the forward rotation (JOG+) switch (X012) to stop the operation in the forward rotation direction.
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
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 not being increased.
