Some amplifiers share the fault output with the enable/disable status output. In this case, a special PLC
code must be written with the following sequence:
• Disable the amplifier fault input (see Ix25)
• Enable the motor (J/ command).
• Wait for the amplifier fault input to be false (monitor Mx23).
• Re-enable the amplifier fault input (see Ix25).
General-Purpose Digital Inputs and Outputs (JOPTO Port)
PMAC’s J5 or JOPTO 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 Acc-21F is a six-foot cable for this purpose. Characteristics of the JOPTO port on
the PMAC:
• 16 I/O points. 100mA per channel, up to 24V
• Hardware selectable between sinking and sourcing in groups of eight; default is all sinking (inputs
can be changed simply by moving a jumper; sourcing outputs must be special-ordered or field-
configured)
• Eight inputs, eight 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
Jumper E7 controls the configuration of the eight inputs. If it connects pins 1 and 2 (the default setting),
the inputs are biased to +5V for the OFF state, and they must be pulled low for the ON state. If E7
connects pins 2 and 3, the inputs are biased to ground for the OFF state, and must be pulled high for the
ON state. In either case, a high voltage is interpreted as a 0 by the PMAC software, and a low voltage is
interpreted as a 1.
Caution:
Do not connect these outputs directly to the supply voltage, or damage to the
PMAC will result from excessive current draw.
Having Jumpers E1 and E2 set wrong can damage the IC. The +V output on this
connector has a 2A fuse, F1, for excessive current protection.
