PALLETIZING
EXECUTE
ERROR
1 The setting of the palletizing condi-
tion configuration file is incomplete.
• Set the palletizing condition setting file to
"Completed."
4 Palletize completion universal out-
put number range exceeds the limit.
• Change the palletize completion universal
output signal number of the palletizing con-
dition setting file in the user output signal
point of contact number.
5 During the palletize start instruction
execution, the palletize start
instruction is executed again (dou-
ble execution).
• Delete the palletize start instruction in the
palletize section.
6 The value of the palletizing number
present value output register (or I
variable) is more than the total
number output register (or I vari-
able).
• Check if the palletizing number of current
position output register (or I variable) and
total number of output register (or I vari-
able) is not changed by another function.
7 Palletize completion universal out-
put signal is turned ON at palletize
start instruction execution.
• Reset the palletize completion universal
output signal.
8 Palletize end instruction is not reg-
istered.
• Register the palletizing end instruction.
4800 WDT ERROR
(CONVERTER)
--- Watchdog timer error in the con-
verter.
No response from the converter.
• Turn the power OFF then back ON after
cooling the power supply unit.
If the error occurs again, contact your
Yaskawa representative.
4850 REGENERA-
TIVE TROUBLE
(SERVO2)
--- Disconnection of SERVOPACK
regenerative resistor or failure of
regenerative transistor is sus-
pected.
• Turn the power OFF and back ON.
• Check the connection of regenerative resis-
tor cable.
• Check the settings for manipulator motion
condition (influence by external force, load
condition).
• Replace the SERVOPACK.
4851 REGENERA-
TIVE OVER-
LOAD (SERVO2)
--- Regeneration energy exceeds the
tolerance when the motor deceler-
ates.
• Turn the power OFF and back ON.
• Check the settings for manipulator motion
condition (influence by external force, load
condition).
• Check the regenerative resistor capacity.
• Replace the SERVOPACK.
4852 OVERVOLTAGE
(SERVO2)
--- The main circuit DC voltage of
SERVOPACK is incorrect.
• Turn the power OFF and back ON.
• Check the SERVOPACK Primary supply
voltage.
• Check the settings for manipulator motion
condition (influence by external force, load
condition).
• Replace the SERVOPACK.
4853 VOLTAGE DROP
(SERVO2)
--- The main circuit DC voltage of
SERVOPACK is incorrect.
• Turn the power OFF and back ON.
• Check the SERVOPACK Primary supply
voltage.
• Check the settings for manipulator motion
condition (influence by external force, load
condition).
• Replace the SERVOPACK.
4854 OVER SPEED
(SERVO2)
--- The rotation speed of the servo
motor is incorrect.
• Turn the power OFF and back ON.
• Check the connections of a motor power
line and an encoder line.
• Check a circumference noise.
• Replace the SERVOPACK.
