The Hytec
IP-SM-8601 is a single-width Industry Pack stepper motor
controller producing four channels of logic level control
signals for an external driver system. To see what Hytec offers for these
systems follow one of these links:_
For small (<1amp) motors, the
8909U low
cost L/R driver.
For larger (up to 6amps bipolar drive) motors, the
MDS8.
An EPICs
driver is available for this card. All
registers exist within the Industry Pack I/O, ID and Interrupt areas; no
memory is present.
Each channel has the
following features:-
-
A 32-bit step register, which sets the number of steps in the next
movement, writeable and readable at any time, which counts down to '0'.
-
A 32-bit absolute position up/down counter, which records movements
(writeable and readable). This counter counts all movements including
JOG. This counter may follow step pulses sent out from the board or
count encoder pulses from an external incremental encoder with
quadrature outputs.
-
A 16-bit Start/Stop Speed Register, which sets the speed at which a
movement will start, programmed in steps per second.
-
A 16-bit High Speed Register, which sets the speed at which the motor
will run after accelerating, programmed in steps per second.
-
A 16-bit Ramp Rate Register, which sets the rate at which speed will
increase or decrease during ramping, programmed in steps per second per
second. Minimum value 64 s/s/s.
-
A 16-bit Control and Status Register through which the status of the
drive, the controller and the limit switches can be observed (run/stop,
hit limit, driver dead etc.).
-
A 16-bit Interrupt Mask Register through which controls which CSR bits
may generate interrupt.
-
Counters can be read on the fly via a shadow register.
-
A ‘Common Start’ register through which one or more channels can be
started simultaneously, visible within each channel’s register area
(write only).
-
Each channel has four logic outputs and 8 logic inputs to cater for a
wide variety of applications.
-
The ability to read the module identity, manufacturer, model, revisions
and serial number from an onboard ID ROM.
