Causes
0 Higher voltage has been applied to the
analog input 1 than the value that has
been set by Pr4.24.
1 Higher voltage has been applied to the
analog input 1 than the value that has
been set by Pr4.27.
2
Higher voltage has been applied to the
analog input 1 than the value that has
been set by Pr4.30.
0 Voltage of the built-in capacitor has fallen
below the specified value because the
power supply or battery for the 17-bit
absolute encoder has been down.
Caution
Once this error occurs, the alarm cannot be cleared until the absolute
encoder is reset.
0 Multi-turn counter of the 17-bit absolute
encoder has exceeded the specified
value.
0 The motor speed has exceeded the
specified value when only the supply
from the battery has been supplied to
17-bit encoder during the power failure.
Caution
Once this error occurs, the alarm cannot be cleared until the absolute
encoder is reset.
0 Encoder initialization error was detected.
0
Single turn counter error of encoder has
been detected.
0 Multi turn counter error of encoder has
been detected.
Measures
• Set up Pr4.24 correctly. Check the
connecting condition of the connector X4.
• Set up Pr4.24 to 0 and invalidate the
protective function.
• Set up Pr4.27 correctly. Check the
connecting condition of the connector X4.
• Set up Pr4.27 to 0 and invalidate the
protective function.
• Set up Pr4.30 correctly. Check the
connecting condition of the connector X4.
• Set up Pr4.30 to 0 and invalidate the
protective function.
After connecting the power supply for the
battery, clear the absolute encoder.
• Set Pr0.15 to 2 to ignore the multi-turn
counter over.
• Limit the travel from the machine origin
within 32767 revolutions.
• Check the supply voltage at the encoder
side (5V±5%)
• Check the connecting condition of the
connector, CN X2.
