4-22 Daughter Boards
Stepper Encoder Daughter
Trio Motion Technology
Choosing an encoder for position verification:
Stepper encoder daughter boards generate fewer pulses than the number of
steps the controller considers the axis to be moving. The daughter board
divides the number of steps the controller according to the axis parameter
MICROSTEP:
If the encoder for position verification should have a number of edges equal to
the number of steps the controller moves by, or an integer factor higher. If a
factor higher is used the
PP_STEP axis parameter should be set.
Example:
A stepper motor has 200 pulses/rev and is driven with MICROSTEP=OFF . The con-
troller therefore moves a distance of 200*16=3200 steps to rotate the motor 1
turn. If an encoder is to be used for position verification the encoder would
therefore need 3200,6400,9600 or 12800 etc.. edges/turn. As the encoder port
will count 4 edges per encoder pulse, the ideal encoder would therefore have
800 pulses/rev or multiples thereof.
MICROSTEP=OFF
a factor of 16 (default mode)
MICROSTEP=ON
a factor of 2
