Pulse and Direction (Stepper) Drivers

The channels provided by the PMAC2A-PC/104 board or the ACC-1P board can output pulse and
direction signals for controlling stepper drivers or hybrid amplifiers. These signals are at TTL levels.

Amplifier Enable Signal (AENAx/DIRn)

Most amplifiers have an enable/disable input that permits complete shutdown of the amplifier regardless
of the voltage of the command signal. PMAC's AENA line is meant for this purpose. AENA1- is pin 33.
This signal is an open-collector output and an external 3.3 k

Ω

pull-up resistor can be used if necessary.

Amplifier Fault Signal (FAULT-)

This input can take a signal from the amplifier so PMAC knows when the amplifier is having problems,
and can shut down action. The polarity is programmable with I-variable Ix25 (I125 for motor #1) and the
return signal is ground (GND). FAULT1- is pin 35. With the default setup, this signal must actively be
pulled low for a fault condition. In this setup, if nothing is wired into this input, PMAC will consider the
motor not to be in a fault condition.

ACC-1P General-Purpose Digital Inputs and Outputs (J7 Port)

ACC-1P J7 connector provides eight general-purpose digital inputs and eight general-purpose digital
outputs. Each input and each output has its own corresponding ground pin in the opposite row. The 34-
pin connector was designed for easy interface to OPTO-22 or equivalent optically isolated I/O modules.
Delta Tau's Accessory 21F is a six-foot cable for this purpose. Characteristics of the JOPTO port on the
PMAC:

•

16 I/O points. 100 mA per channel, up to 24V

•

Hardware selectable between sinking and sourcing in groups of 8; default is all sinking (inputs
can be changed simply by moving a jumper; sourcing outputs must be special-ordered or field-
configured)

•

8 inputs, 8 outputs only; no changes. Parallel (fast) communications to PMAC CPU

•

Not opto-isolated; easily connected to Opto-22 (PB16) or similar modules through ACC-21F
cable
