7. PRODUCT OVERVIEW
7.1. Description of the Product
7.2. SMI21 Control Electronics
The SMI21 electronic control card contains the control electronics for a brushless motor, integrated in the
motor body.
This electronics is used for:
• Power switching of the motor in sine mode (field-oriented control (FOC)).
• Position-Speed-Torque and Current control algorithms.
• Use of preconfigured programs which can perform numerous routine applications.
• Management of different types of operation:
o
"Stand-alone" motor without external PLC.
o
Use with other motors incorporating SMI21 or TNI21 or Motomate electronics.
o
Use with a programmable controller, with the SMI21 simplifying motor management.
• The interface with parameter-definition software installed on the PC:
o
Easy to use, even by a layman, thanks to simplified application programs that are quick to
get up and running.
o
Wide choice of expert programs covering a wide range of applications.
o
USB connection via a commercially-available standard cable (can be supplied on request).
• Management of 6 inputs and 4 outputs to control the motor:
o
2 inputs that can be configured for 0-10 V 10-bit analog or PWM or digital control
o
4 digital inputs
o
1 output that can be configured as PWM or frequency or digital
o
1 output that can be configured as PWM or digital
o
2 digital outputs
As standard, the motors have an internal encoder with 4096 points per revolution that can reach high
positioning and control resolutions.
