3056 Voltage drop
[Axis Data] Detects when the main circuit
power supply be-comes 150V
or less in order to prevent the
motor from abnormal rotation
caused by re-duction of the
main circuit power supply
during motor driving. w Main circuit power supply reduction, open
phase w Main circuit thyristor/diode mixed module fault. See the beginning
concerning MSV-
number. w Check the primary side power supply voltage.
Minimum: 200V - 5%. w Replace the servopack. 3060
3061
3062
3063
3064
3065
3066 Heat sink overheat
[Axis Data] w Main circuit transistor circuit in the servopack overheat. See the beginning
concerning MSV-
number. w Replace the servopack. 3070
3071
3072
3073
3074
3075
3076 Servo blown fuse
[Axis Data] Detects that power 1C is
shortcircuited (when power
1C is short-
circuited, the main circuit
power supply breaks down
and the fuse is blown). w Motor wiring short- circuit grounding fault. w Control board fault. See the beginning
concerning MSV-
number. w Correct the motor main circuit wiring manuall y. w Replace the servopack. 3080

3086 Broken current ref cable
[Axis Data] w Disconnection of cable between MSV01 board and
servopack. See the beginning
concerning MSV-
number. w Cable check, connection check. w Replace the servopack. Alarm code Message Cause Remedial Action
