mAlarm_Servo_Code - The Alarm Code from the SGDH amplifier. The alarm dis-
played on the front panel is identical, but shown in decimal. A value of 99H on the
SGDH is 153 decimal, which means no alarm. See the list below.

Alarm Name Description
2 2 Parameter Breakdown EEPROM data in the servo amplifier is
abnormal.
3 3 Main Circuit Encoder
Error Detection data for the power circuit is
abnormal.
4 4 Parameter Setting Error The parameter setting is outside the allow-
able setting range.
5 5 Servomotor and Amplifier
Combination Error Servo amplifier and servomotor capacities
do not match each other.
10 16 Overcurrent or Heat Sink
Overheated An overcurrent flowed through the IGBT.
Heat sink of servo amplifier is overheated.
30 48 Regeneration Error
Detected Regenerative circuit is faulty. Regenera-
tive resistor is faulty.
32 50 Regenerative Overload Regenerative energy exceeds regenera-
tive resistor capacity.
40 64 Overvoltage Main circuit DC voltage is excessively
high.
41 65 Undervoltage Main circuit DC voltage is excessively low.
51 81 Overspeed Rotational speed of the servo is exces-
sively high.
71 113 Overload: High Load The motor was operating for several sec-
onds to several tens of seconds under a
torque greatly exceeding ratings.
72 114 Overload: Low Load The motor was operating continuously
under a torque exceeding the ratings.
73 115 Dynamic Brake Overload When the dynamic brake was applied,
rotational energy exceeded the capacity of
the dynamic brake resistor.
74 116 Overload of Surge Cur-
rent Limit Resistor The main circuit was frequently turned ON
and OFF.
7A 122 Heat Sink Overload The heat sink of the servo amplifier over-
heated.
81 129 Absolute Encoder Backup
Error All of the power supplies for the absolute
encoder have failed and position data was
cleared.
82 130 Encoder Checksum Error The checksum results of the encoder
memory is abnormal.
83 131 Absolute Encoder Battery
Error Battery voltage for the absolute encoder
has dropped.
