5.1.4 P4 - Motor Feedback / second loop encoder input
P4 is a 15-pin DB connector that contains connections for Hall Effect sensors
and incremental encoder feedback. Refer to the P4 pin assignments table for the
connector pin assignments. Encoder inputs on P4 have 26LS32 or compatible
differential receivers for increased noise immunity. Inputs have all necessary filtering
and line balancing components so no external noise suppression networks are
needed.
All conductors must be enclosed in one shield and jacket around them. Lenze
recommends that each and every pair (for example, EA+ and EA-) be twisted. In order
to satisfy CE requirements, use of an OEM cable is recommended. Contact your
Lenze representative for assistance.
The PositionServo 940 buffers encoder feedback from P4 to P3. Encoder Feedback
channel A on P4, for example, is Buffered Encoder Output channel A on P3. The Hall
sensors from the motor must be wired to the 15-pin connector (P4).
