3.5 Speed feedback
The motor control is based upon the motor speed feedback (sensored software).
The speed transducer is an incremental encoder, with two phases shifted at 90°.
The encoder can be of different types :
-
power supply: +12V / +5V
-
electric output: open collector ( NPN ), push-pull.
COMBI AC0 / ACE0 could also be used without encoder, sensorless control.
This solution has to be discussed with Zapi technicians.

Note (1): The encoder resolution and the motor poles pair (the controller can
handle), is specified in the home page display of the handset showing following
headline:
CA0Z2A
ZP1.00
That means:
CA0Z= COMBIAC0 Zapi controller
2 = motor’s poles pair number
A = 32 pulses/rev encoder
The encoder resolution is given by the second-last letter in the following list:
A = 32 pulses/rev
K = 48 pulses/rev
B = 64 pulses/rev
C = 80 pulses/rev
