common, but their emitters are all common to each other. The maximum allowable voltage
between TB1 terminals 22 (+) and 14 (-) is 30VDC. The maximum allowable current on each
of the TB1 terminals 15 thru 21 is 100 mA. Snubber diodes are built into the outputs. If the
wiring to the external relays is run more than a few feet, additional snubber diodes should
be used at the external relay coils.
Do not run any large solenoid valves or large contactors directly from these outputs.
Use interface relays connected to these outputs to run this other equipment.
The AT SPEED output operates with the AT SPEED indicator on the front panel. The
adjustment of the AT SPEED tolerance is controlled by parameter #12. The AT SPEED
output and the AT SPEED front panel LED work only in the MASTER mode. In SLAVE mode,
the AT SPEED LED and the AT SPEED output are on all of the time, except when changing
to a newly entered ratio..
The other six outputs are controllable by protocol commands through the RS-422 link.
They can also be operated from the keypad on the front (see page 11). These outputs may
be used for run, stop, man/auto, fwd/rev, or for peripheral device control.
By connecting relays to these outputs and using the relays to control the drive, it is
possible to run the DIGIMAX DIGIMAX DIGIMAX DIGIMAX DIGIMAX
®
and motor control entirely through the communications link.

2 DO NOT USE!
3 DO NOT USE!
Terminal 1 on TB2 is used for a hardware reset. When terminal 1 is connected to a
ground (such as TB1 terminal 5), the DIGIMAX
®
resets just as if the power to the unit were
turned off and the power was then turned back on again. The parameters are NOT cleared
by this operation.
It is NOT recommended that wires be permanently attached to these terminals
because there is a possibility that a noise pulse or accidental activation of the switch may
cause an unintentional reset, interrupting normal operation. Such noise may come from
nearby power components or a difference in potential between the case or terminals of the
DIGIMAX DIGIMAX DIGIMAX DIGIMAX DIGIMAX
®
and ground.
DO NOT MAKE ANY CONNECTIONS TO TB2 TERMINALS 2 and 3! These terminals
are used for programming functions. Connecting anything to these inputs will result in
damage to the unit.
