Speed

The speed calculation for the EI7C FS encoder determines the average speed over the last 4 recorded encoder increments. The response time of the encoder evaluation is thus dependent on the actual speed. The fault in the calculated speed value equals a maximum of 1% of the actual speed:

Fault_v_EI7C FS = Actual speed x 1%

Setting the Filter time speed HTL (8708.4) parameter makes it possible to filter the calculated speed via a sliding average value filter with the parameterized length.
