3-6 Selecting Other System Components
If using a motor with the 90VAC brake option, a user-provided relay
may be driven by these outputs up to the specified levels. Refer to
Figure 6.10 on page 6-10 for information about the necessary
hardware connections. Consult the I/O Configuration in the on-line
ULTRA Master help for additional information about the software
parameters.
Selectable Outputs
Two optically isolated, single ended, active high, current sourcing,
discrete output channels provide logic outputs under software control.
Each selectable output channel is capable of sourcing 50 mA
maximum and is optically isolated and short circuit protected.
Auxiliary Encoder Interface
The external encoder I/O port permits quadrature type encoder signals
for applications, such as electronic gearing.
Encoder Inputs
Software automatically selects the appropriate input based on the
command source:
●
Master Encoder
●
Step/Direction
● Step Up/Step Down.
Encoder Output
The resolution of the encoder output channel is under software
control. The motor encoder signal is divided by 1, 2, 4 or 8 to provide
an output from a differential line driver measured in PPR (pulses per
revolution). The maximum encoder frequency output is 1 MHz (4
MHz quadrature).
ULTRA Master Software
A Windows-based software interface provides start-up selections.
Tasks are organized for efficient set up, control and maintenance.
Context sensitive, on-line help provides immediate assistance.
●
Set up is simplified by a series of logically arranged set up
screens.
●
Files can be stored and printed for on-line or off-line modification,
and on-site or off-site back-up.
●
Diagnostic and set up tools make system integration easy.
Note: If a controller requires synchronization to a specific output state,
refer to “IOUT Signal Generation” on page 6-18 for additional
information.
