In addition, an automatic identification of the correction values is possible in ProDrive.
The current and the speed must be entered during the identification (

purpose. The evaluation is determined by a constant current input. The present status is

), the parity bit (

as the monoflop time t

of the encoder are relevant (refer to the according encoder data
sheet).
Parity bit
Up to a maximum of 48 bit data + optional parity bit can be transmitted. In case the parity
bit shall be evaluated, it must be transmitted as the last bit (least-significant bit / LSB). If
the encoder transmits the parity bit at another position then it must be considered as a
data bit and goes into the 48-bit limitation. Then the parity bit is not be checked.
Additional data
If the encoder transmits additional data before and/or after the encoder position, these
can be filed in any scalar and cyclically writable parameters.
If the additional data is not relevant for the application, then the bit number (

) is specified, only - the target parameter however is left empty.
Additional data can be transmitted before the position (MSB) or after the position (LSB).
