Description of Manual (Built-in Positioning Function)
3. CLEAR signal and rotation direction signal
If a high-speed output special adapter (FX3U-2HSY-ADP) is used, the same output will be used for both the CLEAR signal and the rotation direction signal of the DSZR (FNC150) or ZRN (FNC156) instruction. For this reason, it is necessary to change the CLEAR signal output device in order to output the CLEAR signal.
For details on the CLEAR signal device change method, refer to Subsection 4.3.4.

4.6.1 Setting the Command Pulse Method
1. Pulse output method on PLC side1) Main unit (transistor output (sink output))
If the main unit (transistor output (sink output)) is used, the pulse output signals (pulse output destination and rotation direction) will be as shown in the following figure:
*1. "ON" and "OFF" represent the statuses of the PLC output. "H" and "L" respectively represent the HIGH and LOW status of the waveform.
For details on the relationship between the PLC output and the waveform, refer to the following pages.
2) High-speed output special adapter (Pulse train + Direction Setting)
When setting the Output Form Setting Switch of the high speed output special adapter to the "PLSDIR"
position, the pulse output signals (pulse output destination signal and rotation direction signal) will be as shown in the following figure:
*1. "ON" and "OFF" represent the statuses of the PLC output. "H" and "L" respectively represent the HIGH status and the LOW status of the waveform.
For details on the relationship between the high-speed output special adapter output and the waveform, refer to the following pages.
