Stage of power at IGBT with current protections and i 2 t, clamp circuit with external braking resistance.
DSP based on Texas architecture series TMS320 with inner loop of current, speed and position.
Predisposition for resolver, facoder or sinusoidal encoder (sincos) with emulation encoder of A-B-Z type.
Chopper frequency for the regulation of the phase current 5-10KHz.

The converters are equipped with analogic input for speed reference and torque limitation, analogic outputs for inner sizes monitor (speed, current...).
Digital optoinsulated inputs and outputs programmable with several “user” functions as the emergency breaking, the zero torque value, the homing on sensor, lock in torque etc.
Serial interface Rs-232 and CAN bus 2.0B compliant for the configuration with field bus.

Main characteristics

•  Pilotage synchrony brushless servomotors at permanent magnets and at variable reluctance, asynchrony motors and linear motors, with control of torque, speed and position at closed ring (control method PID).
•  Encoder emulation ABZ with selection of number of pulses and memory of the position at power off (back_up).
•  Possibility to use until 4 set of dynamic parameters (torque, ramps, max speed, gains of PID) selectable from private input or with user special functions (thresholds of time or speed, thresholds of torque...).
•  Possibilities of statement of speed or torque limits (current), with active monitoring and comparison of the variable of inner functioning with the presetted limits. Possibility to couple up such variable, inner events or special user functions for the activation of private outputs or the modification of the functioning parameters (set of selectable parameters).
•  Available functioning parameters modification during motor run (gain of PID, ramps, speed).
•  bracking or homing control on sensor with static control of the position (lock in torque).
•  Regulation of the maximum torque(current) with external analog input or inner digital reference (torque motor).
•  Electrical axis on external master encoder.
•  Positioning function via I/O PLC or field bus.
•  inner PLC with logical sequences programming possibility on the I/O or on the inner functioning variable.
•  Possibility of connection with FA-coder, Sin_cos or Resolver.
•  Emulazione step-by-step with interface step/dir.
•  Monitor on PC with possibility of statement/registration set parameters and with real-Time oscilloscope emulation for the loops calibration.
•  Possibilities of monitoring of inner variables (transducer value, current, speed) through two analog outputs 0-10V.
