Description
<variable 1>
=
<output terminal function>
This instruction fetches the on / off status of
<output terminal
function>
of the inverter and stores it in
<variable 1>
.
- Explanation
This instruction fetches the on / off status of the inverter output terminal specified by
<output terminal function>
and stores it
in
<variable 1>
. When the specified output terminal is off, the value of
<variable 1>
is “0”; when it is on, the value of
<variable
1>
is “1”.
The function and operation of the specified output terminal are the same as those that can be specified by the terminal function
(SJ700 /L700/SJ700B: C021 to C026 / WJ200 : C021, C022, and C026) on the inverter. For details, refer to the Inverter
Instruction Manual.
