OUTPUT_OFFSET and 7i43

Does the combination of HM2_7i43 and SV8.bit use the OUTPUT_OFFSET setting or is it ignored?

I have drives that require a 0-5v analog input.. I can not seem to get the OUTPUT_OFFSET setting to work.

From the ini file:
BIAS = 0.00
OUTPUT_SCALE = 4.0
OUTPUT_OFFSET = 0.25
MAX_OUTPUT = 1.0

No matter what setting is use for OUTPUT_OFFSET the output is +-2.5v.
I would like to offset that so it is 0-+5v.


Hardware is:
7i43 + 7i33 + 7i37

Any Thoughts?
Thanks,

The OUTPUT_OFFSET parameter is not used in the hm2-servo HAL file.
If you want to offset the analog out, probably the easiest thing would be to use the sum2
component. and add your offset to the PID output.

Depending on what you are doing the abs component may help as well

Thanks for the tip,

That worked well, The output voltage is in range.
Now I need to find a way to bring the enable line low BEFORE the output slews to zero.

I get a slight tick from the motor when the motors are disabled. When they are first enabled there is no
unexpected movement, only when they are diabled.

I suspect the output is slewing towards zero prior to the enable line going low.

Thanks again

The tick was all tuning.
Adding a little more Derivative did the trick.

Thanks again.
