9.3 Positioning operation based on pulse input
Positioning operation is performed according to the operation data set with the programmable controller.
Follow the steps below to perform positioning operation:
Step 1 Setting the pulse input mode
Step 2 Setting the resolution
Step 3 Setting the motor rotation direction
Step 4 Confirming the absolute system function
Step 5 Performing the positioning operation
Step 1 Setting the pulse input mode
Set a desired pulse input mode of the driver according to the pulse output mode of the controller (pulse
oscillator) used with the driver. The pulse input mode can be set using the pulse input mode selector switch
(SW1-4) on the driver or applicable parameter.
• 1-pulse input mode
A pulse signal is input via the PLS input and the direction is selected using the DIR input.
• 2-pulse input mode
When a pulse signal is input via the CW input, the motor will rotate in forward direction. If a pulse signal is
input via the CCW input, the motor will rotate in reverse direction.
• Phase difference input mode (set by a parameter)
The motor will rotate in forward direction when the CCW input phase is delayed by 90° relative to the CW
input.
The motor will rotate in reverse direction when the CCW input phase is advanced by 90° relative to the
CW input.
