3.4 Speed feedback
The motor control is based upon the motor speed feedback. The speed
transducer is an incremental encoder, with two phases shifted at 90°. The
encoder can be of different types:
- power supply: +5 V or +12 V.
- electric output: open collector ( NPN), push-pull
- standard (A and B) output.
For more details about encoder installation see also chapter 4.2.5.
4 Note: 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:
AE2T2B ZP1.13
That means:
AE2T= ACE-2 traction controller
(AE2P= ACE-2 pump controller)
2 = motor’s poles pair number
B = 64 pulses/rev encoder
The encoder resolution is given by the last letter in the following list:
A = 32 pulses/rev
B = 64 pulses/rev
C = 80 pulses/rev
D = 128 pulses/rev
