4.2.2 Buffered Encoder Output (P3, pins 7-12)
There are many applications where it is desired to close the feedback loop to an
external device. This feature is built into the PositionServo drive and is referred to as
the “Buffered Encoder Output”. If a motor with encoder feedback is being used, the A+,
A-, B+, B-, Z+ and Z- signals are directly passed through the drive through pins 7-12
with no delays, up to a speed of 25MHz. If a motor with resolver feedback is being used
a simulated encoder feedback is transmitted. The default resolution of the simulated
encoder is 1024 pulses per revolution, pre-quad. If a different resolution is desired refer
to section 5.3.22 “Resolver Tracks”.
4.2.3 Digital Outputs
There are a total of five digital outputs (“OUT1” - “OUT4” and “RDY”) available on the
PositionServo drive. These outputs are accessible from the P3 connector. Outputs are
open collector type that are fully isolated from the rest of the drive circuits. See the
following figure for the electrical diagram. These outputs can be either used via the
drives internal User Program or they can be configured as Special Purpose outputs.
When used as Special Purpose, each output (OUT1-OUT4) can be assigned to one of
the following functions:
• Not assigned
• Zero speed
• In-speed window
• Current limit
• Run-time fault
• Ready
• Brake (motor brake release)
Please note that if you assign an output as a Special Purpose Output then that output
can not be utilized by the User Program. The “RDY” Output has a fixed function,
“ENABLE”, which will become active when the drive is enabled and the output power
transistors becomes energized.
