Format 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 (C021 to C026) on the inverter. For details, refer to the SJ700 Series Inverter
Instruction Manual.
- Sample program
(Code area [Code Window])
：
SET-Freq= 6000 : Set the output frequency to 60 Hz.
ACCEL= 1000 : Set the acceleration time to 10 seconds.
DECEL= 1000 : Set the deceleration time to 10 seconds.
FW= 1
wait X(01) = 1 : Wait until X (01) is turned on.
ACCEL= 3000 : Increase the acceleration time to 30
seconds.
wait FA1 = 1 : Wait until the output frequency reaches
the set frequency.
LOOP if X(02) <> 1 then LBL1 : Wait until X (02) is turned on.
SET-Freq= 500 : Reduce the set frequency to 5 Hz.
LBL1 UB(00)= ZS
if UB(00) <> 1 then LOOP
DECEL= 3000 : Increase the deceleration time to 30
seconds when ZS is on.
wait 10.00 : Operate the motor at 5 Hz for 10
seconds.
FW= 0 : Decelerate and stop the motor.
