 Protective Functions
Error detection Description
Control power supply undervoltage
The voltage between P and N in the control voltage converter has dropped below the spec-
ified value.
Overvoltage The voltage between P and N in the converter has exceeded the specified value.
Undervoltage
The main power supply between L1 − L3 was interrupted for longer than the time set in the
Momentary Hold Time (Pn6D) when the Undervoltage Alarm Selection (Pn65) was set to 1.
Alternatively, the voltage between P and N in the main power supply converter dropped be-
low the specified value 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 val-
ue.
Overload
The torque command value exceeded the level set in the Overload Detection Level Setting
(Pn72), resulting in an overload due to the time characteristics.
Regeneration overload The regenerative energy exceeded the capacity of the regeneration resistor.
Encoder communications error
The disconnection detection function was activated because communications 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 encoder is connect-
ed, but there is an error in the communications data.)
Deviation counter overflow
The number of position deviation pulses exceeded the Deviation Counter Overflow Level
(Pn70).
Overspeed
The rotation speed of the Servomotor exceeded the setting of the Overspeed Detection Level
Setting (Pn73).
Command pulse multiplying error
The settings of the gear ratio (Pn48 to Pn4B: Electronic Gear Ratio Numerator 1, Electronic
Gear Ratio Numerator 2, Electronic Gear Ratio Numerator Exponent and Electronic Gear
Ratio Denominator) are not appropriate.
Overrun limit error
The allowable range of movement set in the Overrun Limit Setting (Pn26) was exceeded by
the Servomotor.
EEPROM parameter error
The data in the parameter storage area was corrupted when the data was read from EE-
PROM at power-ON.
EEPROM check code error
The EEPROM write verification data was corrupted when the data was read from EEPROM
at power-ON.
Drive prohibit input
Both the forward and reverse drive prohibit inputs were open when the Drive Prohibit Input
Selection (Pn04) was set to 0 or either the forward or reverse drive prohibit input was open
when the Drive Prohibit Input Selection (Pn04) was set to 2.
Excessive analog input
A voltage exceeding the Speed Command/ Torque Command Input Overflow Level Setting
(Pn71) was applied to the Speed Command Input (REF: CN1 pin 14).
Absolute encoder
system down error The power supply and battery to the absolute encoder went down and the capacitor voltage
dropped 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 encod-
er 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.
Encoder phase Z error A phase Z pulse was not detected regularly for the serial encoder.
Encoder PS signal error A logic error in the PS signal was detected for the serial encoder.
PCL input exceeded A voltage exceeding ± 10 V was applied to the Forward Torque Limit Input (PCL: CN1 pin 16).
NCL input exceeded A voltage exceeding
±
10 V was applied to the Reverse Torque Limit Input (NCL: CN1 pin 18).
Motor automatic recognition error The Servomotor and Servo Drive do not match.
CPU error The Servo Drive or Servomotor failed.
Encoder error The Servo Drive or Servomotor failed.
