3.12 Home Position Detector (HP-sig) Specifications
The home position detector is composed of the mechanical switch. While the carriage is located at the left end, the switch remains ON.

In order to improve reliability, we recommend that the HP-sig is detected as described below.
(1)When the T1-sig is unstable when turning on the power, etc.
Detect the L level after having detected the H level of the HP-sig, and then, after having carried out 81 pulse counts for the T1-sig, detect the H level.
(2)When the T1-sig is decided during continuous operation of the motor
Detect the L level of the HP-sig, and then, after having counted 847 pulses of the T1-sig, detect the H level.
