Pulse Output Timing - NSD ABSOCODER NPG-220HZCLC Specifications & Instruction Manual

9-3-2. Pulse output timing

The pulse is output which is corresponding to the travel distance of the ABSOCODER sensor. The output
pulse signal is different by the function selector switch "sensor travel direction setting".
● Up/down pulse
- If the sensor travel direction setting is OFF (Up pulse), PU side pulse will be output when the
sensor rod travels to the sensor data increase direction indicated in the outer dimension.
If the sensor travel direction setting is ON (Down pulse), PD pulse will be output when the
sensor rod travels to the sensor data increase direction indicated in the outer dimension.
- The pulse which corresponding to the travel amount per 20.3μs is output in constant
period (max. 5MHz).
