Functional and compact scalar frequency inverter SPLC-NLP1000-11G4 is designed for connection to a three-phase network 380 V and control of three-phase asynchronous motors with power up to 11 kW. This frequency inverter can control pumps, conveyor belts, and various machines thanks to fine-tuning of motor start and stop, V/f output characteristic adaptation to different loads, PID control, and programmable operation by a multi-step PLC instruction.
The scalar frequency inverter SPLC-NLP1000-11G4 uses scalar V/f control mode. This mode is relatively simple to set up: precise input of all machine parameters is not required.
The model of the scalar inverter SPLC-NLP1000-11G4 has protection class IP20, so it is recommended to install the device on a DIN rail in specialized cabinets for protection against dust and moisture. If necessary, a removable control panel can be connected to the inverter (not included in the price, supplied by order).

Connection diagram of scalar inverter SPLC-NLP1000-11G4
Power circuit of frequency inverters SPLC-NLP1000-11G4:
- Powered by a three-phase 3ph 380 V AC network 50/60 Hz;
- Linear output voltage ranges from 0 to 380 V, and frequency — within the range of 0.1 to 400 Hz;
- Allowable overload for 60 s — up to 150% of nominal current value (in continuous load operation mode)
Control circuit SPLC-NLP1000-11G4:
- 4DI — four digital inputs, the function of which can be self-defined through the menu options. For example, a digital input can be used for start command, forward run, reverse, stop, jog frequency skip, frequency source switching between X and Y, switching between 16 preset speed frequency values, switching between 4 ramp-up and brake modes, remote frequency increase/decrease, timer start, PID control activation, built-in controller program, etc.
- 1AI — one input, which can be switched using a J2 jumper to accept a corresponding analogue signal by current of 4...20 mA or by voltage of 0...10 V to set the frequency;
- 1DO — one multifunctional digital output (relay), which can be used for ON-OFF output signal on operational state, achieving frequency or time counter, completion of a step or PLC program cycle;
- RS485 — RS485 serial port connector for industrial networking of NL frequency converters, controllers, industrial PCs, etc.
