CHAPTER 2 WIRING
Description of I/O Signals 2-25
2
Start positioning [START]: Sequence input signal (Reference value 4)
Positioning motion is executed according to positioning data or immediate value data sent via RS-485
communications.
This function is enabled only if parameter PA1_01 is “7” (positioning operation).
Function
The positioning motion starts at the activating edge of the start positioning signal.
If PA2_40 (internal positioning data selection) is “1” (enable), the internal positioning data is
enabled. Positioning is made according to positioning addresses AD0 through AD3.
If PA2_40 (internal positioning data selection) is “0” (disable), positioning is made according to the
position data and speed data sent via RS-485 communications.
Check for the active state of the in-position signal (level) to turn the start positioning signal on. The
motor starts to rotate. After rotation begins, the in-position signal is turned off.
Parameter setting
To assign the start positioning signal to a sequence input terminal, specify the corresponding
value (“4”) to the input terminal function setting parameter.
