EtherCAT compatible master board PXEP-CN
EtherCAT communication compatible Main Device PXEP-CN
<Official Release!> EtherCAT-compatible master capable of 31-axis motion control + IO control! Proven track record with various types of slave devices.
We would like to introduce the multifunctional motion controller 'PXEP-CN', which was officially released in August 2023. It is a main device compatible with EtherCAT communication and a multifunctional motion control board. It is capable of controlling 31 axes of motion and IO control. The maximum number of connections is between 31 and 127 (under development). The motion control features include our proprietary pulse generation software "PGS," which implements various functions such as synchronization, axis linkage, homing, speed override, and movement amount override. 【Features】 ■ Capable of 31-axis motion control and IO control ■ Maximum number of connections is between 31 and 127 (under development) ■ Functions available for easy control of CIA401/CIA402 compliant slaves ■ Proven track record with over 50 types of sub-devices from more than 25 companies ■ Application development is possible on a Windows-based system without the need for a special development environment *For more details, please refer to the PDF document or feel free to contact us. *EtherCATⓇ is a patented technology licensed by Beckhoff Automation GmbH in Germany and is a registered trademark.

Detailed information
-
Individual settings for starting and stopping speeds, acceleration time during operation, principle time, target speed, and override of movement amount allow for flexible acceleration and deceleration settings. Settings can be freely adjusted in 1 msec increments between 1 PPS and 400 MPPS.
-
The hard limit stop function allows for separate settings of deceleration when entering the hard limit. Additionally, it is equipped with a soft limit deceleration stop function as well.
-
Interpolation control allows for the recording of interpolation data within the PGS for up to 5000 steps, enabling changes to the interpolation data during operation, modifications and corrections to the target position, and the ability to pause the interpolation operation at any time. Additionally, it is possible to restart from a pause and switch interpolation axes (from XY axis to XZ axis), among other functions.
-
The online soft landing feature allows for the suppression of overshoot during stops with bonding devices, enabling protection of machines, materials, and workpieces.
-
The pitch correction function (pitch error correction function) measures the pitch errors at regular intervals of transmission mechanisms such as screws in advance, and corrects the pitch error by adding the correction amount to the commanded position during the control axis drive for positioning. *Achievement: Improvement of positioning accuracy from 46μm to 3μm, a 15-fold enhancement.
-
The axis linkage function is a feature that controls by adding or subtracting the command position (output pulse) or actual position (input pulse) of one axis to another axis. By linking the work table (such as the XYZ axis) with the encoder information of the conveyor, it is possible to operate without stopping the conveyor.
-
Equipped with gantry control as a basic function. By applying the axis linkage function, the Y2 axis is set to be linked to the Y1 axis, allowing the Y2 axis to automatically follow the Y1 axis with just a command issued to the Y1 axis alone.
-
The trigger input drive function uses general-purpose input as a trigger signal to execute pre-set actions. This function can be used for drive start, synchronous start, and more.
-
The timing output function refers to the ability to emit output signals at specified positions or timings, which can be used to turn ON/OFF devices such as strobes, camera shutters, and sensor equipment.
