If manual handle operation cannot be performed, the probable causes
include the following:
D The servo is not activated.
D Manual pulse generators are not connected properly to the I/O module
with the manual pulse interface.
D The I/O module with the manual pulse interface is not allocated, or is
not allocated properly.
D A related input signal is not input due to a parameter setting error.
Check that the LED on the servo amplifier indicates “0”. If a number
other than “0” is indicated, the servo is not activated. In this state, even
JOG operation and automatic operation cannot be operated.
Check the servo–related parameters and the wiring.
