MODE OF OPERATION
DIGITAL INPUTS
Velocity control. Speed can be selected by digital input from on-board potentiometer, external analog signal, or 7
preset speeds. Accel/decel rate set by on-board potentiometer
Eight inputs, 5-24 VDC, bidirectional (can be driven by sinking or sourcing signals) 2 kHz max freq response. Com-
mon terminal (INCOM) can be connected to an external power supply (5 to 24 VDC), or internally connected to 5V or
GND (selected by internal DIP switches)
CW/CCW: selects direction of motor shaft rotation
STP: commands motor to stop quickly using electromagnetic braking
EN/RE: removes power from motor windings
M0,M1,M2: selects one of seven preset speeds
STMD: selects which mode of stopping is used
SPST: selects whether speed is set by on-board pot or external analog signal
DIGITAL OUTPUTS
30 VDC max, 80 mA max, open collector, open emitter.
FLT is a dedicated fault output.
SPO is a dedicated tachometer output (30 pulses per revolution).
Both outputs can be reconfigred at the factory for qualified OEM applications.
