Dedicated Inputs Setup
The ULTRA Plus or IQ has 16 digital inputs and 8 digital outputs. Some of these inputs and outputs
have dedicated functions associated with them. For example, if the Forward Limit feature is used, the
Forward Limit Switch must be connected to input I1. The input functions are enabled or disabled using
the Inputs dialog box from the Parameters menu:
Display this dialog box and set the inputs as shown and select the OK button. With the inputs set as
shown, only the Jog input functions are active. If input I8 is activated (by connecting P1 pin 9 to P1 pin
1) the motor will accelerate using the Jog Acceleration parameter to the Jog Velocity. If I7 is activated
(by connecting P1 pin 8 to P1 pin 1) the motor will do the same thing, but in the opposite direction. If
both inputs are activated the motor will stop because the ULTRA Plus or IQ is being told to move in
opposite directions at the same speed which results in no movement.
Read Inputs
We will now modify the LEARN.QPS program to look for an input to go on before doing the first move,
and wait for the input to go off before doing the second move. Modify the program to look like this:
TITLE "firstpgm"
WAIT I16=ON
MOVD 10
WAIT I16=OFF
MOVD - 10
END
The program waits for I16 to go on, does a move of ten revolutions, waits for I16 to go off, does a move
of minus ten revolutions and then ends. Compile the program, save it to the ULTRA Plus or IQ, and run
it. When the program is run, the motor will not move until I16 is activated by connecting P2 pin 3 to P1
