11.1.1 Alarm Display Table
The relation between alarm displays and alarm code outputs is shown in Table 11.1.
If an alarm occurs, the servomotor can be stopped by doing either of the following operations.
• DB STOP: Stops the servomotor immediately using the dynamic brake.
• COAST TO A STOP: Stops naturally, with no brake, by using the friction resistance of the motor in oper-

Meaning
EEPROM data of SERVOPACK is
abnormal.
Detection data for power circuit is
abnormal.
The parameter setting is outside the
allowable setting range.
SERVOPACK and servomotor capaci-
ties do not match each other.
The setting of dividing ratio (Pn212) is
not acceptable (out of fixed incre-
ments), or exceeds the value for the
connected, encoder resolution.
*1
When a linear motor is connected:
A value higher than the allowable
maximum dividing ratio calculated on
the base of the linear motor maximum
speed was set in Pn281.
The mounted serial encoder is not sup-
*1
ported by Σ-II series SERVOPACK.
An overcurrent flowed through the
IGBT.
Heat sink of SERVOPACK was over-
heated.
Regenerative transistor or regenerative
resistor is faulty.
Regenerative energy exceeds regener-
ative resistor capacity.
The power supply to the main circuit
does not match the parameter Pn001
setting.
Main circuit DC voltage is excessively
high.
Main circuit DC voltage is excessively
low.
The motor speed is excessively high.
