Alarm Description
It is in error when DSP accesses
EEPROM.
The encoder output exceeds the rated
output frequency.
RS-232/485 communication is in error
RS-232/485 communication time out
Only one single phase is inputted in the
main circuit power.
Early Warning for Overload
The magnetic field of the encoder U, V,
W signal is in error.
The internal memory of the encoder and
the internal counter are in error.
The error of the internal data has been
detected for three times continuously.
The internal reset of the encoder is in
error.
Charging circuit of the servo drive is not
removed and the battery voltage is
higher than the specification (>3.8 V) or
the encoder signal is in error.
The motor crashes the equipment,
reaches the torque of P1-57 and
exceeds the time set by P1-58.
Incorrect wiring of the motor power line
U, V, W, GND or the connection
between both is breakdown.
1. Internal communication error of the
absolute encoder
2. Internal error of other type of
encoder
Encoder temperature exceeds the
