During Startup Fault Symptom Cause Conrming Methods
Input position
reference.
Servo motor does
not rotate.
Input reference pulse
counter (H0B-13) is 0.
High/low-speed pulse input terminal is wired
incorrectly.
When H05-00 = 0 (pulse is main position
reference source), check whether high/low-
speed pulse input terminal is wired correctly
by referring to Chapter 3 in the IS620P User
Manual. Meanwhile, check whether the
setting of H05-01(reference pulse selection) is
matched.
Position reference is not input.
1. Check whether FunIN.13: INHIBIT (pulse
input forbidden) or FunIN.37: PulseInhibit (pulse
forbidden) is used.
2. When H05-00 = 0 (pulse is main position
reference source), host computer or other
pulse generator does not output pulses. Check
whether there are pulses into high/low-speed
pulse input terminal. Please refer to the IS620P
User Manual.
3. When H05-00 = 1 (step reference is main
position reference source), check whether H05-
05 (step amount) is 0. If not, check whether
FunIN.20: PosStep (DI position step reference)
has been allocated and whether logic of
corresponding terminal is valid.
When H05-00 = 2 (multi-position reference is
main position reference source), check whether
parameters in group H11 are set correctly.
If yes, , check whether FunIN.28: PosInSen
(internal multi-position enable) has been
allocated and whether logic of corresponding
terminal is valid.
5. If position change on y is used, check
whether H05-29 (position change on y unlock)
is set to 1(enabled). If yes, check whether
FunIN.29: XintFree (position change on y
unlocked) is used.
Servo motor rotates
in reverse direction.
Input reference pulse
counter (H0B-13) is
negative.
When H05-00 = 0 (pulse is main position
reference source), check whether the setting
of H05-15 (reference pulse form) is consistent
with actual pulse input. If not, it indicates that
H05-15 is set incorrectly or terminal wiring is
incorrect.
When H05-00 = 1 (step reference is main
position reference source), check whether H05-
05 (step amount) is positive or negative.
When H05-00 = 2 (multi-position reference is
main position reference source), check whether
each displacement is positive or negative.
When H05-00 = 2 (multi-position reference is
main position reference source), check whether
each displacement is positive or negative.
Check whether H02-02 (rotation direction
selection) is set correctly.
Servo motor can rotate after preceding fault is removed.
