2.8 Position Detection

2.8.2 Position Detection
Definition
In this mode, the 1Count24V/100kHz counts continuously starting from the load value:
• If the 1Count24V/100kHz reaches the high counting limit when counting up, and another
• If the 1Count24V/100kHz reaches the low counting limit when counting down, and
• The high counting limit is set at +2147483647 (2
• The low counting limit is set to –2147483648 (–2
