FAQ (customer)

• Q: Is this drive suitable for controlling a 0.75 kW pump motor?
  A: Yes, the DG11-301D8FB-A20N is rated for 0.75 kW motors and includes dedicated functions for pump applications such as dry-run protection and PID control.
• Q: Can I use this inverter on a 400 V three-phase supply?
  A: Yes, the drive is designed for 3-phase 380–480 V AC supplies, which includes standard 400 V networks.
• Q: Is the device protected against overload and overheating?
  A: The inverter provides electronic motor overload protection, overcurrent protection and temperature monitoring of the drive to prevent overheating.
• Q: Can I adjust acceleration and deceleration times?
  A: Yes, the DG1 series allows you to freely program acceleration and deceleration ramps and choose appropriate profiles for your application.
• Q: Does it have a built-in keypad and display?
  A: The unit includes an operator panel with a display and keys for parameter setting, status monitoring and local control.
• Q: Is it possible to integrate this drive into an existing automation system?
  A: Yes, the drive offers multiple I/Os and built-in communication capabilities, and can be extended with communication modules to fit your automation network.

FAQ (expert)

• Q: Which control methods are supported for induction and PM motors?
  A: The DG1 family supports V/f control, sensorless vector control and energy-optimised modes for quadratic torque loads, suitable for both induction and permanent magnet motors within its rating.
• Q: What protective functions are available for process-critical applications?
  A: The drive includes overcurrent, motor thermal overload, DC link over/undervoltage, ground fault, phase loss, stall protection and loss-of-load detection, plus configurable alarms and automatic restart.
• Q: Can the internal PID controller be used for pressure or flow regulation?
  A: Yes, the built-in PID can directly control speed based on an analog feedback signal such as pressure, level or flow, making it suitable for pump and fan control loops.
• Q: How is integration with fieldbus systems handled?
  A: The DG1 platform offers on-board communication and optional plug-in modules that support common industrial protocols, enabling easy integration into PLC and BMS networks.
• Q: Are there application macros for quick commissioning?
  A: Yes, the DG1 series provides predefined application macros (e.g. for pumps, fans, conveyors) that pre-configure key parameters to reduce commissioning time.
• Q: What enclosure rating and mounting constraints should be considered?
  A: This model has an IP20 enclosure intended for cabinet mounting; proper ventilation and clearance must be ensured to maintain thermal limits and reliability.

Reviews
