Error Detection Function Detection Details and Cause of Error
11 X Control power supply undervoltage
The DC voltage of the main circuit has
dropped below the specified value.
12 --- Overvoltage
The DC voltage of the main circuit is
abnormally high.
13 X Main power supply undervoltage The DC voltage of the main circuit is low.
14 PR Overcurrent
Overcurrent flowed to the IGBT. Servomotor
power line ground fault or short circuit.
15 PR Servo Drive overheat
The temperature of the Servo Drive radiator
exceeded the specified value.
16 --- Overload
Operation was performed with torque
significantly exceeding the rating for several
seconds to several tens of seconds.
18 PR Regeneration overload
The regenerative energy exceeded the
processing capacity of the regeneration
resistor.
21 PR Encoder communications error
Communications between the encoder and
the Servo Drive failed for a specified number
of times, thereby activating the error detection
function.
23 PR Encoder communications data error
Communications error occurred for the data
from the encoder.
24 --- Deviation counter overflow
The number of position deviation pulses
exceeded the Deviation Counter Overflow
Level (Pn209).
26 --- Overspeed
The rotation speed of the Servomotor
exceeded the setting of the Overspeed
Detection Level Setting (Pn073).
27 PR Command error The operation command resulted in an error.
29 --- Internal deviation counter overflow
The value of the internal deviation counter
(internal control unit) exceeded 2
27
(134217728).
34 --- Overrun limit error
The Servomotor exceeded the allowable
operating range set in the Overrun Limit
Setting (Pn026) with respect to the position
command input.
36
PR
X
Parameter error
Data in the parameter save area was
corrupted when the data was read from the
EEPROM at power-ON.
37
PR
X
Parameter corruption
The EEPROM write verification data was
corrupted when the data was read from the
EEPROM at power-ON.
38 X Drive prohibit input error
Forward and Reverse Drive Prohibit Inputs
(NOT and POT) both became OPEN.
40 PR
Absolute encoder
system down error The voltage supplied to the absolute encoder
dropped below the specified value.
41 PR
Absolute encoder counter
overflow error The multi-turn counter of the absolute
encoder exceeded the specified value.
42 PR
Absolute encoder
overspeed error
The Servomotor rotation speed exceeded the
specified value when power to the absolute
encoder is supplied by the battery only.
44 PR
Absolute encoder
one-turn counter error
A one-turn counter error was detected.
45 PR
Absolute encoder
multi-turn counter error A multi-turn counter error or phase-AB signal
error was detected.
47 ---
Absolute encoder
status error The rotation of the absolute encoder is higher
than the specified value.
