UHV SMD210 Stepper Motor Controller

The SMD210 Stepper motor controller is specifically designed to match AML motors. It drives two motors sequentially under manual control from the front panel; automatically from an internally-stored program or remotely via the serial interface. Manual operation is also available from the front panel switches or a hand-held joystick.




Drives 2 UHV stepper motors sequentially.

Advanced low-power drive techniques for minimum motor temperature rise and outgassing and maximum operating time.

Phase currents can be set from 0.1 to 1A in increments of 0.1A.

Holding torque can be controlled independently of dynamic torque under program control, to reduce

Full, half, ÷4, ÷8 step drive modes with automatic transition at user selectable speeds.

Thermocouple amplifiers (type K) for motor temperature indication, protection and control of motor

RS232C interface for host computer control. Drive programs can be developed and run from the computer console (Remote Program Control) or downloaded for stand-alone operation (Internal Program Control).

Motors may be operated manually with the front panel ‘STEP’ switches or with a joystick. Single-step or
multiple-step operation with smooth acceleration to the selected speed.

3 user inputs for interaction with program execution, in addition to two “End of travel” inputs for each

3 user outputs for switching under program control.

Simple control language has many powerful commands, allowing control of all aspects of motion or
position. Conditional operation, loops and jumps are possible.

1U high full-width, steel-cased instrument for easy rack-mounting.

Operates from 100 to 240V, 50/60 Hz supply.
