OM9399SP

PIN DESCRIPTIONS / FUNCTIONALITY

PWMTRIP - A logic low at this input places all six PWM outputs in the OFF state. Otherwise, this

pin is pulled up to +5V onboard.

+28V – This supply is required to generate logic supplies (+15V / +5V) onboard.

Direction - This logic input is used to select the motor direction.

Speed In - This input is the analog command input to the OM9399SP.

Reset - A logic low at this input initiates a complete hardware reset of the DSP.

AUX_PWM - This output is an auxiliary PWM output.

Logic_Gnd - This pin provides the reference point for the command section.

TFS1 - This pin is left open during normal operation. It is dedicated for engineering purposes only.

RFS1 - This pin is left open during normal operation. It is dedicated for engineering purposes only.

Logic_Gnd - This pin provides the reference point for the +15V supply.

Reset_RS-232 - A logic low at this input initiates a complete hardware reset of the DSP. This reset is

provided through the RS-232 interface.

DR1B - This pin is dedicated as the data receive pin for the RS-232 interface. Note that an isolated RS-232

interface is offered with the OM9399SP. Consult the factory for more information.

Logic_Gnd - This pin provides the reference point for the RS-232 interface.

DT1 - This pin is dedicated as the data transmit pin for the RS-232 interface. Note that an isolated RS-232

interface is offered with the OM9399SP. Consult the factory for more information.

+15V - This supply is provided for the Hall effect sensor bias.

Hall_1 - This pin is dedicated to the phase A Hall effect sensor output.

Hall_2 - This pin is dedicated to the phase B Hall effect sensor output.

Hall_3 - This pin is dedicated to the phase C Hall effect sensor output.

Logic_Gnd - These pins provide the reference point for the +28V supply.

Voltage Bus - This terminal is connected to the positive terminal of the 270V supply.

Bus Return - This terminal is connected to the negative terminal of the 270V supply.

Phase A - This terminal is connected to the phase A motor lead.

Phase B - This terminal is connected to the phase B motor lead.

Phase C - This terminal is connected to the phase C motor lead.
