Servo

connected

Operation

release

Z-phase detection time

out

Cause

: This indicates the Z-phase could not be detected at

the first servo-on or home-return operation after the

power is turned ON in Simple Absolute type.

1) Connector connection error or wire breakage on

an actuator cable.

2) Brake cannot be released on a controller

equipped with a brake.

3) Detection of the motor is not performed properly

because an external force is applied.

4) The slide resistance of the actuator itself is large.

Treatment : 1) Check for the actuator cable wiring condition.

2) Check the wiring condition of the brake cable,

and also turn on/off the brake release switch to

see if the brake makes a “clicking” sound. If the

brake is not making any noise, check if the

power is supplied to the brake properly.

3) Check if there is any abnormality in the parts

assembly condition.

4) It the transportation weight is in the acceptable

range, cut off the power to check the slide

resistance manually by moving with hand.

If the actuator itself is suspected to be the cause,

please contact IAI.

Cold start

Magnetic pole

indeterminacy

Cause

: It shows the magnetic pole phase could not be

detected after a certain time being passed even

though the process for the magnetic pole phase

detection was executed at the first servo-on after

the power is turned ON.

1) Connector connection error or wire breakage on

an actuator cable.

2) Brake cannot be released on a controller

equipped with a brake.

3) Detection of the motor is not performed properly

because an external force is applied.

4) The slide resistance of the actuator itself is large.

Treatment : 1) Check for the actuator cable wiring condition.

2) Check the wiring condition of the brake cable,
