Drop in control
supply voltage
Cause
: The control power voltage dropped
less than the voltage drop threshold
(80% of 24V DC = 19.2V).
1) The voltage of 24V DC power
supply is low.
2) Components’ malfunction of the
controller inside the ERC3 motor
unit
Treatment : Check the voltage of the power supply.
In the case that the voltage is normal,
please contact IAI.

Drive Source
Error
Cause
: 1) Motor power input voltage (input to
MP+ of ERC3) is too high for
Position Mode 1, MEC Mode 1 and
Pulse Train Control Mode
Motor power input voltage (input to
MPI of PIO Converter) is too high
for Positioner Mode 2 and MEC
Mode 2
During acceleration/deceleration
and servo-on, the current
consumption rises transiently. Using
the remote sensing function with a
power supply with no enough
current capacity may cause
overvoltage responding to the
current change.
2) Overcurrent is generated on the
motor power supply line
Treatment : 1) Check the power supply voltage
input to MP+ of ERC3 for Position
Mode 1, MEC Mode 1 and Pulse
Train Control Mode.
Check the power supply voltage
input to MPI of PIO Converter for
Position Mode 2 and MEC Mode 2.
Think to use a power supply with
enough current capacity or not to
use the remote sensing function.

Overflow with
Home Return
Incomplete
Cause
: This alarm indicates that the position
deviation counter has overflowed.
1) The speed dropped or stopped
during JOG move due to an impact
of external force, hit to the
mechanical end or overload.
2) The excited-phase detection
operation following the power-on is
unstable.
Treatment : 1) This error occurs when the actuator
cannot be operated as it is
commanded. Check the load
conditions such as if the work is
touching to the surrounding object,
or brake is properly released, and
remove the cause.
2) Overload is concerned. Revise the
transportable weight.
