RUN mode cannot be invoked with the RUN/HOLD key

Cause

Program selected in READY mode is unset.

Select the set program.

It is not possible to change to the RUN mode

 

if CH1 and CH2 programs are not set in

 

synchronous mode (variable parameter

 

PA04 set to 1)

 

Set to END mode.

Set READY mode to execute RESET operation (PROG +

 

RUN/HOLD keys).

 

 

Set to key lock.

Set variable parameter PA01 between 0 to 2.

 

 

HOLD mode cannot be invoked with the RUN/HOLD key
