case, the SW must know the encoder resolution together with the poles-pair
number. The encoder resolution and the motor poles pair (the controller can
handle), will be specified in the headline of the handset showing something
like:
EPSAC0O2A ZP0.91
That means:
EPSAC0=Eps-ac0 steering controller
O= Open Loop (Stepper motor)
2= poles pair number
A= 32 pulses/rev encoder
ZP= SW release type Zapi
0.70= SW release number 0.70
The command configuration is specified through the first letter after EPSAC0
in the following list:
O= Open Loop (Stepper Motor)
C= Closed Loop (Twin Pot)
The encoder resolution is given by the last letter before of the SW release in
the following list:
Q= 4 pulses/rev
S= 6 pulses/rev
W= 16 pulses/rev
A= 32 pulses/rev
K= 48 pulses/rev
B= 64 pulses/rev
The letters to specify the poles pair number and the Encoder resolution are
present only if the SW includes the function for controlling the motor with the
encoder.
