Error detection Description
Control power supply undervoltage
The voltage between P and N in the control voltage converter has dropped
below the specified value.
Overvoltage
The voltage between P and N in the converter has exceeded the specified
value.
Undervoltage
The main power supply between L1 and L3 was interrupted for longer than
the time set in the Momentary Hold Time (Pn06D) when the Undervoltage
Alarm Selection (Pn065) was set to 1. Alternatively, the voltage between P
and N in the main power supply converter dropped below the specified val-
ue while the Servo Drive was ON.
Overcurrent The current flowing to the converter exceeded the specified value.
Overheating
The temperature of the Servo Drive radiator or power elements exceeded
the specified value.
Overload
The torque command value exceeded the level set in the Overload Detec-
tion Level Setting (Pn072), resulting in an overload due to the time charac-
teristics.
Regeneration overload
The regenerative energy exceeded the capacity of the regeneration resis-
tor.
Encoder communications error
The disconnection detection function was activated because communica-
tions between the encoder and Servo Drive were interrupted for a specified
number of times.
Encoder communications data error
There was an error in the communications data from the encoder. (The en-
coder is connected, but there is an error in the communications data.)
Deviation counter overflow
The number of position deviation pulses exceeded the Deviation Counter
Overflow Level (Pn209).
Overspeed
The rotation speed of the Servomotor exceeded the setting of the Over-
speed Detection Level Setting (Pn073).
Command error The operation command ended in an error.
Internal deviation counter overflow
The value of the deviation counter (internal control unit) exceeded
2
27
(134217728).
Overrun limit error
The allowable range of movement set in the Overrun Limit Setting (Pn026)
was exceeded by the Servomotor.
Parameter error
The data in the parameter storage area was corrupted when the data was
read from EEPROM at power-ON.
Parameter corruption
The EEPROM write verification data was corrupted when the data was
read from EEPROM at power-ON.
Drive prohibit input error
Both the Forward and Reverse Drive Prohibit Inputs were open when the
Drive Prohibit Input Selection (Pn004) was set to 0 or either the forward or
reverse drive prohibit input was open when the Drive Prohibit Input Selec-
tion (Pn004) was set to 2.
Absolute encoder system
down error
The power supply and battery to the absolute encoder went down below
the specified value.
Absolute encoder counter
overflow error
The multiturn counter for the absolute encoder has exceeded the specified
value.
Absolute encoder overspeed
error
The Servomotor speed exceeded the specified value when the power to
the absolute encoder was interrupted and power was supplied only from
the battery.
Absolute encoder one-turn
counter error
An error was detected in the one-turn counter for the absolute encoder.
Absolute encoder multi-turn
counter error
An error was detected in the multiturn counter for the absolute encoder.
Absolute encoder status
error
The number of rotations of the encoder exceeded the specified value when
the power supply was turned ON.
