Module EtherCAT Slave điều khiển 1 trục động cơ bước ICP DAS ECAT-2091S
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 maximum motor coil current of 1.5A is being supported. 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 has to be done by the EtherCAT master and the application program. The stepper motor driver automatically controls the torque and position of the motor. 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. 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.
