Emergency stop signal was
input to the head unit.
(Head axis stopped.)
1) Turn the emergency stop switch
clockwise to reset.(One position
each at front side and rear side)
2) If the machine fails to be restored
even after pressing the emergency
stop switch, the switch may be
broken.Contact PFSC.
1645
Improper procedure was
taken in software processing.
(Unsupported command in
the head command issued.)
Close the error screen and perform
origin return. Then, restart
production. Check the situation of
the error occurred and error
message, and contact PFSC.
1646
Improper procedure was
taken in software processing.
e.g.: 2 has been set although
available parameter is 0 or 1.
(Invalid parameter setting.)
Close the error screen and perform
origin return. Then, restart
production. Check the situation of
the error occurred and error
message, and contact PFSC.

Error Code
Error Message
Cause Inspection and Solution
Check sum error occurred in
the communication data from
the host to the head.
(Communication error
occurred.)
Clean the drawer connectors for
connecting head, and check the
wiring connected to them. If the
error persists, contact PFSC.
1648
Communication with the
encoder failed to finish
properly during origin return
immediately after power ON.
(Magnetic pole detection
error occurred.)
Check the connection between the
head motor and control board inside
the head and restart production.
Then, check the situation of the
error occurred and error message,
and contact PFSC.
1649
Origin return failed to finish
within the prescribed time
and timeout occurred.
(Head axis did not properly
return to origin. )
Check the situation of the error
occurred and error message, and
contact PFSC.
1650
Positional deviation with
power ON or integrated
current is beyond the
specified value.
(Head movement stopped
due to overload.)
Check the situation of the error
occurred and error message, and
contact PFSC.

Cause Inspection and Solution
Invalid motor encoder value.
(Head movement stopped.)
Check the connection between the
head motor and control board inside
the head and restart production.
Then, check the situation of the
error occurred and error message,
and contact PFSC.
1652
Current exceeding the
specified value has flown
during head movement.
(Abnormal voltage of current
was supplied to the head
motor.)
Check the situation of the error
occurred and error message, and
contact PFSC.
1653
Cushion end sensor was
blocked at a timing other
than the height measurement.
(Axis stopped.)
Check the installation condition of
the cushion end sensor and make
sure the head does not interfere.
1656
Improper procedure was
taken in software processing.
(Power ON command was
issued for the head specified
as bad head.)
Close the error screen and restart
production. Then, check the
situation of the error occurred and
error message, and contact PFSC.
