where:
N: Period of a single analog sine\cosine. Typically in mm/inches
L: Length of the linear sensor. Typically in meters/legs
Both N and L must be the same (distance) units.
• Total counts per revolution– displays the final calculated user resolution
• Additional Commutation Sensor- The commutation sensor in absolute encoders is
derived from the analog signals (sine/cosine). In cases where the sensor is not
located on the motor and the motor is mounted with Digital Halls, the “Additional
Commutation Sensor” enables correction of the commutation angle in each Hall
edge. The feature is available for the Cornet, Tuba, Cello, Didge, Eagle, Falcon and
Drum products for rotary and linear motors.
• Change…- The push button introduces the “Low Pass Filter” window. The low
pass filter filters the analog signals for Speed-Readout. By default there is “no value”
and “Not Configured!” appears. By clicking on “Change…”, the user can apply any
filter and see the theoretical step response of his/her choice. Typical values for this
filter are between 400-700Kz.
