Inputs
Electrical Characteristics for all Inputs: ..........
Differential. 1500 Vac/dc opto-isolated. Can be
wired as single ended inputs.
Indexer .... Motor steps on high going pulse.
250 nS min. pulse width, 2 MHz
maximum input frequency. 500 nS
minimum dwell time between direc-
tion changes.
Disable .... Programmable Active State (ON or
OFF). Disables current to motor.
Driver does not accept steps while dis-
abled.
Fault Output
Electrical Characteristics:
Open Collector/Emitter. 1500 Vac/dc
opto-isolated. 30Vdc, 20 mA max.
The Fault Output is normally on. Turns off under
the following conditions:
Reset ............... The driver initialization is not
yet complete on power up.
Short Circuit .... Motor Phase to Phase or Phase
to Earth Ground
Over Temp ...... Heat Sink temperature exceeds
90° C (195° F)
No Motor ........ The motor interlock terminals
are not connected.
Pulse Train Input
Switch selectable to CW/CCW or Step/Direction.
Motor Current
Switch selectable from 1.0 to 4.0A
RMS
in 0.1
Amp steps.
Idle Current Reduction
Switch selectable to Not reduced, To 69%, To
50%, or To 0%. Motor current is reduced to
selected level if a step pulse is not received for
one second for the To 50%, and To 0% settings.
For the To 69%, setting, current is reduced after
10 milliseconds. Current is restored to full
value on next pulse.
Resolution
Switch selectable to 200, 400, 1,000, 2,000,
5,000, 10,000, 12,800, 18,000 20,000, 21,600,
