2.7.4 Motor Connector (J4)
The motor connector provides the high voltage 3-phase outputs from the amplifier/switcher to the motor.
Pin # Signal Description
1 MotorC Leg 3 of 3 motor coil connections
2 MotorB Leg 2 of 3 motor coil connections
3 MotorA Leg 1 of 3 motor coil connections
2.7.5 Host Connector (J6)
The Host connector inputs and outputs various non-motor related signals to/from the Developer’s Kit card
Pin # Signal Description
1 Estop This digital input provides an emergency stop signal to the Developer’s Kit card.
Although its function and interpretation are programmable, normally a high signal
(greater than 1.5V) indicates an emergency stop is not active; and a low signal (less than
.5V) indicates that it is active. If unused this signal may be left unconnected.
2 AmplifierDisable This digital output signal provides a programmable output signal indicating the internal
state of the MC73110. Normally, a low output indicates an error, while a high signal
indicates no error. In addition to being an output at this connector, this signal is also used
internally by the MC73110 Developer’s Kit card to shut down the amplifier’s switchers
when the amplifier operates in ‘internal switcher’ mode.
3 GND This signal provides a digital ground return.
4 DigitalCmdClk This digital input signal provides the SPI datastream ‘clock’ signal.
5 DigitalCmdData This digital input signal provides the SPI datastream ‘data’ signal
6 GND This signal provides a digital ground return.
7 +5V This signal outputs provides 5V to external circuitry.

An This analog input signal provides the positive input of the analog command. Depending on
how the MC73110’s control loop has been programmed, this signal represents the
desired voltage, torque or velocity. The input range is +/-10V. The reference input can be
differential or single-ended.
11 AnalogCmd- This analog input signal provides the negative input of the analog command. Depending
on how the MC73110’s control loop has been programmed, this signal represents the
desired voltage, torque or velocity. The input range is +/-10V. The reference input can be
differential or single-ended. When it is single-ended, AnalogCmd- must be connected to
AGND, pin 12.
12 AGND This signal provides an analog ground return
