be used. Single-ended inputs can be used but are not recommended. Sinking type
outputs cannot be used if single-ended inputs are used. The function of these
master gearing/step and
direction inputs is software selectable. Use the
MotionView software, General category, to choose the desirable function
.
An external pulse train signal (step) supplied by an external device, such as a PLC
or stepper indexer, can control the speed and position of the servo motor. The
speed of the motor is controlled by the frequency of the step signal, and the
number of pulses that are supplied to the Kinetix 300 drive determines the
position of the servo motor. Direction input controls direction of the motion.
Buffered Encoder Outputs
There are many applications where it is desired to close the feedback loop to an
external device. This feature is accessible through the buffered encoder output
connections (IOD-7…IOD-12) for TTL differential line encoder types. A
master drive powering a motor with a SICK-Stegmann or Tamagawa high-
resolution encoder does not generate buffered encoder outputs for master gearing
to a slave drive.
If a motor with encoder feedback is being used, the A+, A-, B+, B-, Z+, and Z-
signals are passed directly through drive pins IOD-7…IOD-12 with no filtering,
up to a speed of 2 MHz. The encoder pass through delay is approximately 100 ns.
IMPORTANT
The buffered encoder outputs are not compatible with SICK-Stegmann or
Tamagawa high-resolution motor feedback.
