Timing Of The Zero Point Setting When Using A Hold Signal - NSD Absocoder NCV-40H Series Specifications & Instruction Manual

8-6-4. Timing of the Zero Point Setting when Using a HOLD Signal

Indicates the timing when setting either transparent format or PC synchro format of HOLD input.
(1) Transparent format
In the case of setting the zero point during HOLD input is ON by transparent format, turning
OFF HOLD input allows outputting the "position data after setting the zero point".
If the zero point setting is input when HOLD signal is OFF state, the timing will be same procedure as
"8-6-3. Timing of the Zero Point Setting when Using a Latch Pulse Signal".

Important
Even if the zero point setting input turns ON during HOLD input is ON, the position data won't be updated.
The position data must be read after HOLD input is OFF.
(2) PC synchro format
In the case of setting the zero point by PC synchro format, changing HOLD input allows outputting
"the position data after setting the zero point".

Important
The position data output is not updated only by turning ON the zero point setting input.
The position data must be read after switching HOLD input.
