It uses phaseA and phaseB together to know the direction.
It reads incremental signals input in the 2 phases.
An up/down edge is regarded as 1 count,
in other words, please input a quarter of 1 signal period.
For example
In the case when you combine a HTGA with the displacement scale which uses line driver output
with 20μm signal period.
-
>20μm/4 = 5μm, therefore, “0.005” should be input as a manual coefficient values.
●
When you choose [Manual], make sure to check the difference between the displayed
displacement value and the actual displacement, by using digital length meter and so on.
●The battery is consumed more when connected with a test stand with linear scale.
Please connect AC adapter or charge frequently when long hours operation.
9.2.2. Connectable displacement scale
Please use displacement scale to meet the followings.
Output specifications of displacement scale
- Line driver output * Line receiver in accordance with RS-422/485must be built-in.
- Open collector output *Voltage difference between points of contact must be below 0.5V.
* Some displacement scale may not work.
* There are some displacement scales which we have inspected their working condition with HTGA
series.
Please contact us for further information.
Voltage and current from a HTGA torque gauge to a displacement meter
HTGA series can provide voltage up to DC+5V, and current up to 200mA to displacement meters.
When you would like to supply power from a HTGA to external equipment, please
Make sure to connect it to an included AC adapter.
* Operation of this instrument could be unstable when over 200mA is provided.
