Precautions during operation

The following details must be understood before carrying out JOG operation.

(1) For safety, first set "

Cd.17

JOG speed" to a smaller value and check the

movement. Then gradually increase the value.

(2)An axis error will occur and the operation will not start (error code: 300) if the "JOG speed" is outside the setting range at the JOG start.

(3)An axis error will occur and the operation will not start (error code: 956) if

" Pr.31 JOG speed limit value" is set to a value larger than " Pr.8 speed limit

value".

(4)If " Cd.17 JOG speed" exceeds the speed set in " Pr.31 JOG speed limit value", the workpiece will move at the " Pr.31 JOG speed limit value" and an "Axis warning" will occur in the QD75 (warning code: 301).

(5)The JOG operation can be continued even if an "Axis warning" has occurred.

(6)A JOG start signal OFF ON immediately after the stop signal ON OFF (within 100ms) will be ignored. (The operation will not start.)

(7) Set a "0" in "

Cd.16

inching movement amount". If a value other than "0" is

set, the operation will become an inching operation (Refer to Section 11.3 "Inching operation").

Errors during operation

When the operation is stopped by the stroke limit (limit signal OFF), JOG operation can be performed in the direction in which the limit signal turns ON after an error reset. (An error will occur again if the JOG start signal in the direction in which the limit signal turns OFF is turned ON.)
