PROBABLE CAUSE
・Wiring to the Y axis stepping motor or the PF axis stepping motor
is short circuited.
・The load on the XY table or the PF axis is too large.
・The PF axis encoder connector has not been firmly inserted.
・The signal from the PF axis encoder has been disconnected.
・There is a trouble of current detection circuit on the PMD board.
・There is a trouble of current detection circuit on the PMD board.
・The position of the presser foot is at the lower end or the presser
foot is hit to obstacle.
・The connector of PF axis home position sensor has not been firmly
inserted.
・The signal from the PF axis home position sensor has been
disconnected.
・The connector of PF axis stepping motor cable has not been firmly
inserted.
・The PF axis stepping motor cable has been disconnected.
・Wiring to the Y axis stepping motor is short circuited.
・The load on the XY table is too large.
・Internal 12 V power is decrease or short-circuited by trouble in the
CPU board.
・Internal 12 V power is decrease or short-circuited by trouble in the
SRV board.
・External 12V power is short-circuited or decrease by the trouble of
the operation panel.
・External 12V power is short-circuited or decrease by the trouble of
the I/F board or the halt switch lamp.
・There is a trouble in the CPU board or 5V power supply is short-
circuited.
