Note: To maintain the switching times and edge steepness of the
encoder, the cable length dependent on the sampling rate
and the supply voltage must not be exceeded. Therefore
please refer to the manufacturer's data sheet.
Parameters of the encoder evaluation subject area
Only inputs ISD02 and ISD03 can be used for encoder evaluation; see
section 5.2.3 “_21ID-Digital inputs”.

Explanatory notes
• On the inverter module the A and B track of a HTL encoder can be
evaluated. Differential transducers cannot be evaluated.
• Permissible pulse counts are in the range 2
n
withn=5to14.
• For speed control the encoder signal in the inverter module is quad-
rupled, so a good level of speed control is possible with small pulse
counts.
