The voltage between P and N in the control voltage converter has dropped
below the specified value.
The voltage between P and N in the converter has exceeded the specified
value.
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.
The current flowing to the converter exceeded the specified value.
The temperature of the Servo Drive radiator or power elements exceeded
the specified value.
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.
The regenerative energy exceeded the capacity of the regeneration resis-
tor.
The disconnection detection function was activated because communica-
tions between the encoder and Servo Drive were interrupted for a specified
number of times.
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.)
The number of position deviation pulses exceeded the Deviation Counter
Overflow Level (Pn209).
The rotation speed of the Servomotor exceeded the setting of the Over-
speed Detection Level Setting (Pn073).
The operation command ended in an error.
The value of the deviation counter (internal control unit) exceeded
27
2 (134217728).
The allowable range of movement set in the Overrun Limit Setting (Pn026)
was exceeded by the Servomotor.
The data in the parameter storage area was corrupted when the data was
read from EEPROM at power-ON.
The EEPROM write verification data was corrupted when the data was
read from EEPROM at power-ON.
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.
The power supply and battery to the absolute encoder went down and the
ABS
capacitor voltage dropped below the specified value.
The multiturn counter for the absolute encoder has exceeded the specified
ABS
value.
The Servomotor speed exceeded the specified value when the power to
the absolute encoder was interrupted and power was supplied only from
ABS
the battery.
An error was detected in the one-turn counter for the absolute encoder.
ABS
An error was detected in the multiturn counter for the absolute encoder.
ABS
The number of rotations of the encoder exceeded the specified value when
ABS
the power supply was turned ON.
