Eight Lead Motor Connected in Parallel
Connecting Input Signals
The NI SMD-761x has three types of input:
•
High speed digital inputs for step and direction commands/encoder use 5 V logic.
•
Digital inputs for other signals use 12 to 24 V logic.
•
Analog inputs are reserved for furture use.
Note
All inputs except STEP and DIR use 12 to 24 VDC logic.
All drives include eight digital inputs and two analog inputs:
•
CW & CCW Limit: These are optional input that can be used to inhibit motion in a given
direction, forcing the motor and the load to travel within mechanical limits. It can be
configured as active closed or active open.
•
IN1/STEP & IN2/DIR: These are digital signals that can be used for commanding a
position. Quadrature signals from encoders can also be used. These inputs can also be
connected to sensors and switches.
•
IN3, IN4, IN5, IN6: These are software-prgrammable inputs that can be used for motor
enable, alarm reset, or jogging. These inputs can also be connected to sensors and switches.
Note
These drives can use input signals from a motion controller or accept ethernet
streaming commands. For more information on commanding the drive using
Ethernet, see the
