The connections highlighted in the figures above are provided below in table form.
The following sections provide detailed information on all of the connectors on the N-Series DK Interconnect boards.
1.9.2 Feedback Connector (J3)
The following table details the Feedback Connector (J3), which is an 8-pin jackscrew style connector.
Signal Pin # Comments
Feedback Connector (J3)
+5V 1 +5V and GND may be used to power the encoder
GND 2
, QuadA1- 3, 4 Encoder optional for step motors. If single-ended encoders used connect to +
(positive) only
, QuadB1- 5, 6
Index+, Index- 7, 8 Most encoders provide an Index pulse, which is useful for homing or for
detecting lost encoder counts
Motion Signals Connector (J6)
PosLim, NegLim 1, 2 Optional but frequently used signals to detect travelling beyond motion range
of machine.
Home 3 Optional but frequently used signal to home the motor axis after startup
Enable 4 Enable signal must be driven low for N-Series ION to function. This is most
easily accomplished by jumpering to pin 8 (GND) of this connector
Brake 7 Optional but frequently used safety signal to shut down motor operation
GND 8 Ground
Hall Signals Connector (J4)
HallA, HallB, HallC 1, 2, 3 Used with Brushless DC motors only
GND 4 Ground return for Hall sensors
Programming Connector (J9)
Srl3Xmt, Srl3Rcv 1, 2 These pins provide a serial connection that will be used for first time opera-
tion of the DK board. The USB to 3-pin programming cable included with the
developer kit connects to this port.
GND 3
HV Power Connector (J1)
HV Aux, HV 1, 2 HV Aux and HV are usually tied together. They provide power for the inter-
nal unit logic after conversion by internal DC to DC and drive the motor
coils. Must be in the range of 12 - 56V
GND 3 Power Ground Return
Motor Drive Connector (J2)
Motor A-D 1, 2, 3, 4 Drive connections to motor.
Motor A & B are used with DC Brush motors
Motor A, B, C are used with Brushless DC motors
Motor A & B drive phase A of step motors
Motor C & D drive phase B of step motors
Case/shield 5 A case/shield connection is strongly recommended for most motor setups.
Pin # Signal Name Description
1 +5V +5V power output which may be used to power the motor’s encoder circuitry
2 GND This is the preferred ground connection for the quadrature and Index signal inputs
3 Differential A+ quadrature input. optional for step motor
4 QuadA1- Differential A- quadrature input. optional for step motor
5 Differential B+ quadrature input. optional for step motor
6 QuadB1- Differential B- quadrature input. optional for step motor
