The TJ1-FL02 can generate pulses to drive an external stepper
motor amplifier. You can use single step, half step and micro-
stepping drivers with this interface. Applicable signals:
•
Enable
•
Step
•
Direction.
3.8.8
Registration
The TJ1-FL02 can capture the position of an axis in a register when
an event occurs. The event is called the print registration input. On
the rising or falling edge of an input signal (either the Z marker or
an input), the TJ1-FL02 captures the position of an axis in
hardware. You can use this position to correct possible errors
between the actual position and the desired position. You set up the
print registration with the
REGIST
command.
The position is captured in hardware and therefore there is no
software overhead. This eliminates the need to deal with timing
issues.
Because the registration inputs are very fast, they are susceptible
to noise in combination with slow rising and falling edges. To
counter this problem, you can use a digital noise filter. Use of the
noise filter increases the response time from 0.5
μ
s to 3.5
μ
s.
We refer to the
REGIST
command in the Trajexia Programming
Manual for more information on using the registration inputs.
