OMC510

PIN DESCRIPTIONS / FUNCTIONALITY

Direction (J1-1)—This logic input is used to select the motor direction.

Speed In (J1-2)—This input is the analog command input to the OMC510.

Reset (J1-3)— A logic low at this input initiates a complete hardware reset of the DSP.

Aux_PWM (J1-4)—This output is an auxiliary PWM output.

Logic_Gnd (J1-5)—This pin provides the reference point for the command section.

TFS1 (J1-6)—This pin is left open during normal operation. It is dedicated for engineering purposes only.

RFS1 (J1-7)—This pin is left open during normal operation. It is dedicated for engineering purposes only.

+5V (J1-8)—This supply is provided for the RS-232 interface. Note that an isolated RS-232 interface is

offered with the OMC510. Consult the factory for more information.

Logic_Gnd (J1-9)—This pin provides the reference point for the +5V supply.

Reset_RS-232 (J1-10)— A logic low at this input initiates a complete hardware reset of the DSP. This reset

is provided through the RS-232 interface.

DR1B (J1-11)—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 OMC510. Consult the factory for more information.

Logic_Gnd (J1-12)—This pin provides the reference point for the RS-232 interface.

DT1 (J1-13)—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 OMC510. Consult the factory for more information.

+15V (J2-1)—This supply is provided for the Hall effect sensor bias.

Hall_1 (J2-2)—This pin is dedicated to the phase A Hall effect sensor output.

Hall_2 (J2-3)—This pin is dedicated to the phase B Hall effect sensor output.

Hall_3 (J2-4)—This pin is dedicated to the phase C Hall effect sensor output.

Logic_Gnd (J2-6)—This pin provides the reference point for the +15V supply.

Voltage Bus (VBUS)—This terminal is connected to the positive terminal of the 28V supply.

Bus Return (BRTN)—This terminal is connected to the negative terminal of the 28V supply.

Phase A (PH_A)—This terminal is connected to the phase A motor lead.

Phase B (PH_B)—This terminal is connected to the phase B motor lead.

Phase C (PH_C)—This terminal is connected to the phase C motor lead.
