The back to back inverter is controlled by the N-DFGC module.
•N-SERIN/CA-1K. Computer Controlled Advanced Industrial Servosystems Trainer (for AC Motors).
The AEL-SERIN/CA-1K allows to generate wind curves configured by the user through the AELWPP/CCSOF software.
The AEL-SERIN/CA-1K trainer consists on an Control Interface module connected to a three-phase motor and a computer (AEL-PC). The control interface has an 20-bits incremental encoder that controls the speed, position and torque of the motor.
The USB communication between the control interface and the PC provides the AEL-SERIN/CA-1K the possibility of commanding the motor from the PC and visualize the most important signals of the motor: Velocity, Position and Torque Control.
Control Interface module:
3 Digital outputs:
Each output has a green LED that indicates if the output is active or not.
Encoder outputs:
Two pair 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.
3 Analog outputs: can be controlled by software to be a certain valve of the internal variables.
6 Digital inputs: digital inputs for those signals that are introduced to enable the different available functions in the software.
6 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.
6 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.
1 Potentiometers. 1 Digital encoder.
Reset button: this button is used to reset the motor driver after setting a new configuration.
