Alarm code
11 The PN voltage of the main power supply
converter section dropped during servo ON.
12 The line voltage is too high.
(253 VAC or more)
14 The electric current flowing in the converter
section is too large.
15 The amplifier is overheated.
16 Overload
18 The regenerative energy exceeded the
regenerative resistor processing capacity.
21 Communication between the motor encoder and
the servo amplifier was broken. (Detection of
disconnection)
23 Data from the motor encoder resulted in a
communication error.
24 The motor operation does not follow the
instruction from the KGTSM (GMSC).
26 The number of motor rotations exceeded the
standard.
27 The parameter setting is not appropriate.
29 The deviation counter value in the servo amplifier
exceeded the standard.
34 The parameters are not set correctly.
36 When parameters are read from the EEPROM
after the power is turned ON, the data storage
area is damaged.
37 The parameters read from the EEPROM when
the power was turned ON are incorrect.
38 Both the CW and CCW drive inhibit inputs were
set to OFF.
48 Motor error
49 Motor error
 Mismatch between the motor and amplifier
95
 Internal encoder wire of the motor is
disconnected.
96 Amplifier error
Others Amplifier error when an error occurs repeatedly.
