I/O & RS-232 SPECIFICATIONS

Analog Inputs

1 analog input—0 to 3V input with 10-bit resolution. This input is the speed input.

Logic Inputs

2 logic inputs—2V threshold. These inputs are the direction and reset inputs.

RS-232 Communications

All control functions and data are available through an isolated RS-232 port. A serial cable,

complete with isolated RS-232 circuitry can be provided by the factory. Consult the factory for

details.

MODE of OPERATION

Speed Mode

The OMC510 accepts speed commands from either an isolated RS-232 port or an analog input. The speed

command is compared with the estimated shaft speed and the motor torque is controlled to regulate the shaft

speed with a Proportional-Integral (PI) regulator.
