Vector frequency converter 2.2 kW, 380V (SPLC-AT20-2R2G4)

Three-phase frequency converters SPLC-AT20-2R2G4 are powered by three-phase voltage 380 V and designed to control three-phase asynchronous motors with a voltage of up to 2.2 kW.

The frequency converter models of the series SPLC-AT20-2R2G4 can switch to modes:

• Precise vector control with open loop (sensorless)
• Easy-to-configure vector control, involving voltage/frequency regulation. This mode is less precise but allows working with motors of higher power.

Main parameters of SPLC-AT20-2R2G4:

• Maximum output frequency up to 600 Hz, resolution for digital frequency setting 0.01 Hz;
• Rated supply of frequency converter — 3ph ~380V 50/60 Hz;
• Overload capacity: operation for 60 s with exceeding rated current up to 150%, for 3 s — up to 180% (in “R” mode overloading 120% is allowed for 60 s, 150% — not more than 3 s);
• Number of inputs-outputs of the frequency converter:
  • Input terminals: 6 multifunctional digital inputs (two of them high-speed pulse) and 2 analogue (one 0…20 mA or 0…10 V, the other only 0…10 V);
  • Output terminals: 2 relay outputs, 1 high-speed pulse output (transistor open collector), 2 analogue outputs (0…20 mA or 0…10 V);
  • Communication port RS-485 (Modbus).
• PID control with feedback;
• Internal controller (PLC);
• Remote control panel (LCD display, indicators, configurable buttons). By default, the detachable operator panel is mounted on the device, and for remote connection, you need to additionally order and purchase a connector (not included in the frequency converter price).

Main features of SPLC-AT20-2R2G4::

• The main and auxiliary frequency setting sources can be used, their synthesis, switch between sources in various ways. Frequency settings possible through:
  • Digital setting with buttons on the operator panel in the corresponding menu item;
  • Digital setting through UP/DOWN; terminals
  • Digital setting through RS-485; port
  • Potentiometer connected to the frequency converter;
  • Multi-step speed with 16 preset speeds with duration up to 6500.0 hours, acceleration/braking time of each step;
  • Closed-loop PID regulation, with switchable PID parameters;
  • Analogue electrical signal;
  • High-speed pulse signal.
• Maintaining initial frequency up to 100.0 s;
• Force motor stop through DC braking;
• Choice of acceleration/braking time and mode — linear or S-curve;
• Sleep mode with activation periods to prevent water freezing;
• “Jog” mode JOG;
• Protection functions:
  • Menu access password protection;
  • Protection of the motor, frequency converter from overload;
  • Module overheating detection;
  • Phase failure detection at input/output;
  • RS-485 response time exceeding detection;
  • Over and under voltage protection;
  • Sensor failure detection for PID feedback;
  • Warning of low/high water pressure, engine stop when lack of water;
  • Display of 25 types of errors.
