3026 Servo on
defective DB
[Axis Data] w DB OFF of servopack at servo ON does not work
well. w Fault of monitor CPU for servo (MSV) See the beginning
concerning MSV-
number. wTurn OFF the power and then turn it ON again. w Replace the servopack. 3030

3036 Regenerative
trouble
[Axis Data] Detects a regenerative circuit
fault such as a regenerative
transistor shortcircuit, or
regene-rative registor discon-
nection, etc. w Control board fault.
w Regenerative transistor fault
w Regenerative resistor disconnection. See the beginning
concerning MSV-
number. w Replace the servopack.
w Check the regenerative resistor and replace the servopack. w Review the operating condition. 3040

3046 Overvoltage
[Axis Data] Detects when the main circuit
power supply exceeds the
allowable value because of
insufficient regenerative pro-
cess or excessive regenera-
tion.
Detection voltage:
400 to 420V. w Load inertia is too large
w Regenerative processing circuit fault. w Power supply voltage is too large. See the beginning
concerning MSV-
number. w Check machine side inertia in motor axis
conversion. w Replace the servopack.
w Check the primary side power supply voltage.
(Maximum: 220V +10%). w Review the operating condition. Alarm code Message Cause Remedial Action
