8.2 Internal registers
8.2.44 Analogue Filtered
Description: These eight registers hold the software-filtered analogue value of each of the eight I/O’s:
IO-1 to IO-8. Their values are updated every ten milliseconds. See the AFZUP_xx reg-
isters 100-106 for the filter parameters. Important: Also read the section on analogue
filters in this manual.
To use the unfiltered values of the inputs for faster updates, but with no noise immunity,
use registers 89-96 instead ( Analogue In , page 206).
An input voltage of 5.00 Volts corresponds to a register value of 4095.

8.2.45 Analogue In
Description: These eight registers hold the unfiltered analogue value of each of the eight I/Os: IO-1
to IO-8. Their values are updated approximately every 1 ms.
To use the filtered values of the inputs for better noise immunity, use registers 81-88 in-
stead ( Analogue Filtered , page 206).
An input voltage of 5.00 Volts corresponds to a register value of 4095.

8.2.46 Busvol
Description: The supply voltage inside the motor is continually measured and stored in this register.
This value is the basis for the warnings and errors of Low Bus Voltage and Over Voltage.
8.2.47 Min_Busvol
Description: Trigger point for under-voltage
