Input the
position
reference.
The servo
motor does
not rotate.
The input
reference pulse
counter (H0B-
13) is 0.
•
The high/low-speed pulse input terminal is wired
incorrectly.
When H05-00 = 0 (pulse reference is the main
position reference source), check whether the
high/low-speed pulse input terminal is wired
correctly by referring to Chapter 3 Wiring of Servo
System. Meanwhile, check whether the setting of
H05-01(Reference pulse selection) is matched.
•
The position reference is not input.
Check whether the DI function FunIN.13: INHIBIT
(pulse input forbidden) or FunIN.37: PulseInhibit
(pulse reference forbidden) is used.
When H05-00 = 0 (pulse reference is the main
position reference source), the host computer or
other pulse generator does not output pulses.
Check whether there are pulses into the high/
low-speed pulse input terminal. Please refer to
Chapter 3 Wiring of Servo System.
When H05-00 = 1 (step reference is the main
position reference source), check whether H05-
05 (step size) is 0. If not, check whether the DI
function FunIN.20: PosStep (DI position step
reference) has been allocated and whether the
logic of the corresponding terminal is effective.
When H05-00 = 2 (multi-position reference is the
main position reference source), check whether
parameters in group H11 are set correctly. If
yes, check whether the DI function FunIN.28:
PosInSen (internal multi-position enable) has
been allocated and whether the logic of the
corresponding terminal is effective.
If the interruption xed length function is used,
check whether H05-29 (interruption xed length
unlock) is 1 (enabled). If yes, check whether the
DI function FunIN.29: XintFree (interruption xed
length cleared) is used.
