DESCRIPTION

The OMC507 is a three phase brushless DC Motor Controller Driver. The OMC507 is a 2

quadrant controller and provides control of motor current (torque) in proportion to the input

current command. The versatility of the OMC507 allows the user to either provide an analog

or a TTL PWM current command signal externally, or to set an analog current command

onboard. The OMC507 also allows the user to adjust the current command offset onboard

through the use of a potentiometer. Loop compensation is provided onboard and loop

compensation component values can be modified to meet specific customer requirements,

thereby optimizing the controller for each application.

The OMC507 controller utilizes surface mount and through hole technology. The OMC507

is a mere 2 1/2 inches in diameter and can fit inside the motor housing. A connector for the

control section is optional; consult the factory.

This table shows the Phase Output state versus

the state of the Hall-Effect and Direction Inputs.

Please note that the Hall-Effect Inputs are

Grey-encoded; that is, only one input is allowed

to change from one input state to another at a

tm.

The commutation coding shown reflects Hall-

Effect sensors that are spaced at 120

mechanical increments.

Also, internal

protection logic disables all three Phase

Outputs when the Hall-Effect Inputs are set to
