Siemens Micromaster 6SE9211-5BA40 MM25 AC servo motor driver, input 208-240VAC output 3~ 1.5A 0-400Hz 250W

Features:

• Microprocessor control for reliability and flexibility.
• Remote control capability via RS485 serial link using the USS protocol.
• Ability to control up to 31 inverters via the USS protocol.
• A comprehensive range of parameters is provided to enable the inverters to be configured for use in almost any application.
• Built-in non-volatile memory for storing parameter settings.
• Factory default parameter settings preprogrammed for European requirements.
• Output frequency (and hence motor speed) can be controlled by:
  • Digital frequency setpoint
  • Analogue setpoint (voltage input)
  • Motor potentiometer
  • Fixed frequency
  • Via remote data transmission
• Built-in DC injection brake.
• Built-in brake chopper for external resistor
• Integral RFI filter.
• Automatic load compensation by flux current control.
• Built-in ramp generator for variable ramping times.
• Membrane type front panel controls.
• Relay output.
• External connection for optional enhanced operator panel or for use as external RS485 interface.
• Closed loop control using a standard Proportional, Integral, Derivative (PID) control loop function.
