• Check the target position speci-

fication.

• Check the forward software

limit in PnB21.

• Check the moving mode

(rotary or linear) set in PnB20.

• If software limits are not being

used, either select a rotary

moving mode in PnB20 or dis-

able the software limits by set-

E4EE A.A9F

Moving Disabled Error

due to N-LS

The specified target position exceeds the posi-

tion reference of reverse software limit set in

PnB23.

• Check the target position speci-

fication.

• Check the reverse software

limit in PnB23.

• Check the moving mode

(rotary or linear) set in PnB20.

• If software limits are not being

Position Reference

Out-of-range Error

The moving method is set to rotary (PnB20 =

1, 2, or 3) and the target position specification

exceeds the position reference limits in PnB21

and PnB23.

• Check the target position speci-

Target Position

Unspecified Error

Even though the target position was not speci-

fied even once, there was a request by the ST

the RS command to start registration position-

ing.

Specify a target position with a

command such as the POS com-

mand, STnnnnnnnn command, or

RSnnnnnnnn command.
