• N-SERINCA1K. Advanced Industrial Servosystems Module for AC Motors.
  The “N-SERINCA1K” allows to generate wind curves configured by the user through the
  AEL-WPP/CCSOF software.
  The “N-SERINCA1K” consists of a control interface module connected to a three-phase motor
  and a computer (AEL-PC). The control interface has a 20-bit incremental encoder that controls the
  N-SERINCA1K
  speed, position and torque of the motor.
  The USB communication between the control interface and the PC gives the “N-SERINCA1K”
• the possibility to control the motor from the PC and to display the most important motor signals:
  torque, position and speed control.
• Control Interface module:
• Three digital outputs:
  Each output has a green LED that indicates if the output is active or not.
• Encoder outputs:
  Two pairs of outputs (CH A Out, CH B Out and their respective denied outputs) that are TTL
  signals of incremental position generated by the encoder feedback. These signals indicate the
  direction of rotation of the motor.
  One pair of outputs (CH Z Out and their denied) that TTL works as marker of pulses. This
  signal indicates the motor speed.
• Relay output: this output is a relay, and it belongs together with the output 4 that it can be in the
  software inside the I/O digital label.
• Three analog outputs: can be controlled by software to be a certain valve of the internal variables.
• Six digital inputs: digital inputs for those signals that are introduced to enable the different
  available functions in the software.
• Six buttons: they are good to enable the digital inputs. When the button is pressed, the digital
  Input will be activated, making what has been defined by the software.
• Six switches: they have the same function as the buttons, but with the only difference that they are
  switches and, therefore, maintain the position fixed (open or closed).
• Switch outfitter of digital inputs: there is a switch that enables the digital inputs. When the green
  LED is on, the inputs will be enabled.
• Analog input: this input allows an analog use directly of the user. It is an A/D input.
  Potentiometer. Digital encoder.
• Reset button: this button is used to reset the motor driver after setting a new configuration.
• Motor:
• 3PH AC motor, 2 kW, 5 A, 5000 rpm, 400 VAC, 19.1 Nm, IP67, 20 bits (1048576 resolution)
  incremental encoder.
• N-SERINCA1K/CCSOF: Data Management Software + Data Acquisition + Computer Control:
  Compatible with actual Windows operating systems. Graphic and intuitive simulation of the
  process in screen. Compatible with the industry standards.
  Registration and visualization of all process variables in an automatic and simultaneous way.
  Flexible open and multicontrol software, developed with actual windows graphic systems, acting
  simultaneously on all process parameters. Management, processing, comparison and storage
  N-SERINCA1K/CCSOF
  of data. Comparative analysis of the obtained data, after the process and modification of the
  conditions during the process.
