Note
For single-ended encoders, leave the complementary signal pins
floating – do not ground them. Alternately, some open collector
single ended encoders may require tying the negative pins to
ground in series with a 1-2 KOhm resistors.
Some motor manufacturers bundle the hall sensors with the
motor-lead cable. The hall sensors must be brought into J7
connector.
Setting up Quadrature Encoders
Digital Quadrature Encoders use the 1/T incremental entry in the encoder conversion table. Position and
velocity pointers should, by default, be valid and in most cases no software setup is required, activating
(Ixx00=1) the corresponding channel is sufficient to see encoder counts in the position window when the
motor/encoder shaft is moved by hand.
I100,4,100 = 1 ; Servo IC0 Channels 1-4 activated
I500,4,100 = 1 ; Servo IC0 Channels 5-8 activated
(First Acc-1P)
I900,4,100 = 1 ; Servo IC0 Channels 9-12 activated
(Second Acc-1P)
Setting up Sinusoidal Encoders
For sinusoidal position feedback, the Acc-51S, sine wave input interpolator, stacks on top of the Turbo
PMAC Clipper or on top of the Acc-1P 5-8 axis board. Channels 1 – 4 of the ACC-51S correspond to
PMAC channels 1 – 4 if the ACC-51S is connected to the main Turbo PMAC Clipper; channels 1 – 4 of
the ACC-51S correspond to PMAC channels 5 – 8 if the ACC-51S is connected to the ACC-1P board.
