DA180 series basic AC servo drive
Code Name
Er13-0 Main circuit overvoltage
Er13-1 Main circuit undervoltage
Er17-0 Drive overload
Possible cause
2. There is damage to the
internal pulse frequency
detection circuit of the drive.
The DC voltage of the drive
main circuit is higher than
the specified voltage.
1. The grid voltage is too
high.
2. No brake resistor or pipe
is connected during braking
or the brake resistor is
damaged.
3. The DEC time in the stop
process is too short.
4. The internal DC voltage
detection circuit of the drive
is damaged.
The DC voltage of the drive
main circuit is higher than
the specified voltage.
1. The grid voltage is too low.
2. The buffer relay is not
closed.
3. The drive output power is
too high.
4. The internal DC voltage
detection circuit of the drive
is damaged.
The short-time load on the
drive is too heavy.

Fault handling
Workaround
1. Ensure the grid input voltage is
within the allowed range.
2. Ensure the internal brake
resistor is not loose or damaged.
Ensure the external brake resistor
is not damaged.
3. Increase the DEC time.
4. Check R0.07 when the drive is
disabled. If it is abnormal and
does not match the grid input
voltage, replace the drive.
1. Ensure the grid input voltage is
within the allowed range.
2. Repower on the drive. Ensure
the buffer relay is closed. If the
buffer relay is closed, there is a
sound indicating actuation.
3. Check R0.07 when the drive is
disabled. If it is abnormal and
does not match the grid input
voltage, replace the drive.
1. Reduce the drive load.
2. Ensure there is no phase
dislocation or phase loss to the
UVW wiring of the motor and the
encoder is correct.
3. Ensure the motor matches the
drive.
