    ECAT-2091S ~ NEW ~

    Single Axis Stepper Motor Controller/ Driver

           
    		 

    The ECAT-2091S stepper motor controller is a cost-effective, two-phase bipolar stepper driver. A motor voltage range between 5 and 46V DC and a peak motor coil current of 1.5A without cooling is being supported. When operating in a properly ventilated environment (cooling fan) the ECAT-2091S can drive the axis at a current level of up to 2.0A. The maximum running motor current, microstep resolution and other motion parameters are software selectable.

    The ECAT-2091S is a standard EtherCAT slave and an EtherCAT master is required to operate the device. The ECAT-2091S supports three operation modes: Free-Run, SM synchron and Distributed Clock (DC).

    Two-phase bipolar stepper motors can be directly connected to the ECAT-2091S device. The device is designed to operate in a open loop. Configuration and motion control has to be done by the EtherCAT master and the application program. The coil current and step control done by a stepper motor driver IC. An integrated ramp generator automatically calculates the acceleration and deceleration distance. In position mode the controller drives the motor to the target position and in velocity mode accelerates the motor to the target velocity. A minimum set of configuration data consists of acceleration, deceleration and maximum motion velocity. After receiving the target position the motor driver starts controlling the motion movement. All motion parameters can be changed on the fly.

    The ECAT-2091S has a 32 bit high frequency encoder counter which counts the input signal of an external  incremental  encoder.  The  encoder  can  for example be used for  homing  purposes  and  for consistency checks.

    High resolution of up to 256 microsteps per full step is supported for a ensuring smooth and precise motor operation.

    Two digital input channels are provided. The digital inputs can be set to act as a simple DI, as a left and right hardware limit switch which automatically stops the motor when activated, or a latch trigger for latching the current motor and encoder position.

    The module must be supplied by two power sources. A motor supply and a 24Vdc control supply.
