Error Code
Error Message
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.
1666
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.
1667
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.
1668
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.

Error Code
Error Message
Cause Inspection and Solution
No response from the head
or feeder cart.
(Communication timeout
error occurred.)
Clean the drawer connectors for
connecting head and feeder cart,
and check the wiring connected to
them. If the error persists, contact
PFSC.
1670
Error occurred in
communication with the head
or feeder cart.
(Communication failure)
Clean the drawer connectors for
connecting head and feeder cart,
and check the wiring connected to
them. If the error persists, contact
PFSC.
1671
Check sum error occurred in
communication data from the
head or feeder cart to the
host.
(Communication error
occurred.)
Clean the drawer connectors for
connecting head and feeder cart,
and check the wiring connected to
them. If the error persists, contact
PFSC.
1672
Miswiring of the
thermocouple^ broken wire
or short-circuit occurred.
(Temperature cannot be
measured properly.)
Check the wiring of the
thermocouple.

Error Message
Cause Inspection and Solution
Heater cable is broken or
thermocouple on the heater
side is disconnected.
(Heater temperature does
not rise.)
Check the wiring of the heater or
thermocouple.
1701
Broken communication cable
between the head PCB and
temperature controller PCB.
(Communication failure)
Check the communication cable
between the head PCB and
temperature controller board.
1702
PCB cooling fan stopped.
(Communication failure)
Check the wiring between the head
PCB and board cooling fan.
1703
Motor cooling fan stopped.
(Communication failure)
Check the wiring between the head
PCB and motor cooling fan.
1704
24V power voltage has
dropped to less than 19V.
(Communication failure)
Check the 24V power supply.
