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.
