Logic Output Signals
Four optically isolated outputs are
available on the 2CN connector.
Each output will source a
maximum of 20 mA. The common
(0VI) of these outputs are pins 26
through 32. A brief description of
the outputs follows; the pin
numbers are shown in
parenthesis. Figure 3-7 shows the
typical circuitry of an output.
READY(42): This output (RDY)
indicates proper power is applied
and no faults are present.
POSITION ERROR(43): This
output (POS) indicates that an
error has occurred when the
controller is operating in the
Position mode.
SZ(44): The indication of this
output (SZ) depends on the mode
selected: SPEED/TORQUE:
Indicates that the drive is
operating at a speed less than the
value determined by the PG pot.
POSITION: Indicates that
positioning is complete.
WARNING
THIS DRIVE IS CAPABLE
OF OPERATING AT AND
MAINTAINING ZERO
SPEED. THE USER IS RE-
SPONSIBLE FOR ASSUR-
ING SAFE CONDITIONS
FOR OPERATING PERSON-
NEL BY PROVIDING SUIT-
ABLE GUARDS AND AU-
DIBLE OR VISUAL ALARMS
OR OTHER DEVICES TO
INDICATE THAT THE DRIVE
IS OPERATING OR MAY BE
OPERATING AT OR NEAR
ZERO SPEED. FAILURE TO
OBSERVE THESE PRE-
CAUTIONS COULD RE-
SULT IN BODILY INJURY.
ROTATION DIRECTION (45): This
output (DIR) indicates motor
rotation direction. ON indicates
counterclockwise rotation when
viewed from the shaft end. The
drive does not have to be in RUN
mode. Output stays latched until a
change in direction occurs.
* Required input resistance to limit current draw.
