12.4.3 Analog Servo Alarm List
The Servo Driver Error Flag (IL 04, bit 0) turns ON when an alarm has occurred in a SERVOPACK connected to
the SVA-01 Module.
The content of the alarm can be confirmed by connecting a Digital Operator to the SERVOPACK.
The following tables show the alarms that can occur in the SGDA, SGDB, SGDM, SGDH, and SGDS SERVOPACKs.

A.00
Absolute Value
Data Error Absolute data cannot be received or the received abso-
lute data is invalid.
× ×
A.02 Parameter Corrupted A parameter checksum error was detected.
A.03
Main Circuit Detector
Error There was an error in the power circuit's detection
data.
× ×
A.04
Parameter Setting
Error A parameter value setting exceeded the allowed set-
ting range.
A.05 Combination Error
The motor and SERVOPACK capacity settings are
incompatible.
× ×
A.09 Divider Setting Error
An invalid Divider Setting (Pn212) was set (between
increments) or the setting exceeds the connected
Encoder's resolution.
× × ×
When a linear motor is connected, the setting exceeds
the maximum dividing ratio (Pn281), which was cal-
culated from the linear motor's maximum speed.
× × ×
A.0A
Encoder Type
Mismatch A serial encoder has been mounted that is not sup-
ported by the
Σ-II.
× × ×
A.10
Overcurrent or
Heat Sink Overheat There was an overcurrent in the power transistor.
The heat sink overheated (SGDM).
A.30 Regeneration Error
An error occurred in the regeneration processing cir-
cuit.
A.31
Position Error Pulse
Overflow The position error pulses exceeded the “Overflow”
limit set in the parameters.
× ×
A.32
Regeneration
Overload The regenerative energy exceeds the regenerative
resistor's capacity.
× ×
A.33
Main Circuit Wiring
Error The power supply method used to supply the main cir-
cuit does not match the setting in parameter Pn001.
× ×
A.40 Overvoltage
The power supply voltage to the main circuit is exces-
sively high.
A.41 Undervoltage
The power supply voltage to the main circuit is too
low.
× ×
A.51 Overspeed The motor's speed is too high.
A.70 Overload
The torque exceeded the rated torque (high or low
load).
× × ×
A.71 Overload (High Load)
The torque significantly exceeded the rated torque for
several seconds to several dozen seconds.
×
A.72 Overload (Low Load)
The motor is operating continuously at a torque
exceeding the rated torque.
×
A.73 DB Overload
During dynamic braking operation, the rotating energy
exceeds the DB resistor's capacity.
× ×
A.74
Inrush Resistance Over-
load The main circuit power supply was turned OFF and
ON repeatedly.
× ×
A.7A Heat Sink Overheat The SERVOPACK’s heat sink overheated. × ×
A.80
Absolute Encoder
Error The “Number of Pulses per Absolute Encoder Rota-
tion” value is incorrect.
× ×
A.81
Absolute Encoder
Backup Error The encoder power supplies are all down and the posi-
tion data was cleared.
