The ECAT-2094S stepper motor controller is a cost-effective, two-phase bipolar stepper driver. The ECAT-2094S simultaneously controls up to four stepper motors. A motor voltage range between 6 and 46V DC and a maximum motor coil current of 1.5A/phaseis being supported. The running motor current, microstep resolution and other motion parameters are software selectable.

Two-phase bipolar stepper motors can be directly connected to the ECAT-2094S device. The device is designed to operate in a open loop. Configuration and motion control has to be done by the EtherCAT MDevice and the application program. The torque and step control is done by an internal stepper motor driver IC. Each stepper motor is being independently controlled by a separated driver IC. The four driver ICs are not synchronized and work independently from each other. An integrated ramp generator automatically calculates the acceleration and deceleration distance. The motion controller drives the motor to the target position or accelerates the motor to the target velocity. All motion parameters can be changed on the fly. 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.

The ECAT-2094s has four integrated incremental encoder interfaces. Four 32 bit high frequency encoder counter counts the input signal of external incremental encoders. 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.
