EM-314A STEPPER MOTOR DRIVER 6A 12-24V microstepping, index and Modbus interface

85,00 € /kpl

EM-314A is a bipolar chopper type microstepping stepper motor controller. The bipolar operation principle suits most stepper motors and provides the best torque. The microstepping function also enables great performance at low rpm. The stepping and current regulation have been synchronized, providing smooth and quiet operating. There are 7 different stepping options to choose from, ranging from full- to 1/64-step operation. This provides various possibilities for different speed applications.
The controller has its own auxiliary oscillator, which can be used for preset speed driving. The preset speeds can be activated by using 4 digital function inputs. The oscillator features an acceleration ramp function, which allows frequencies to be altered flexibly. The motor will also start up reliably even to higher frequencies and it is possible to shift to the desired velocity without a pace drop. The auxiliary oscillator includes an indexing part, which offers the possibility of running presettable operating sequences. These sequences can be activated with 4 digital inputs. A sequence is a movement with the selected speed, direction and distance (as steps). All of the inputs are activated with positive logic commands. So the commands and functions are activated by connecting the input to a positive voltage. Control can also be done with TTL-logic level commands. Newest firmware version there is also possibility analog speed control and Modbus RTU
control with Rs-485 port
All of the controller settings are made digitally, using a separate setting device, EM-236 Interface Unit. With this device the settings are easily copied to multiple controllers.
