Wiring diagram for the three-phase scalar inverter SPLC-NLP1000-2R2G4

Power circuit of SPLC-NLP1000-2R2G4 frequency inverters:

• Powered from a three-phase network 3ph 380 V AC 50/60 Hz;
• The linear output voltage is from 0 to 380 V and the frequency is in the range from 0.1 to 400 Hz;
• Permissible overload for 60s — up to 150% of the nominal current value (in constant load mode)

Control circuit SPLC-NLP1000-2R2G4:

• 4DI — four digital inputs, the function of which can be self-determined by choosing from the menu. For example, a digital input can be used for a start command, forward run, reverse, stop, frequency JOG skipping, switching between frequency sources X and Y, switching between 16 pre-set speed frequency values, switching between 4 acceleration and deceleration modes, remote frequency increase/decrease, timer start, PID control activation, built-in controller program start, etc.
• 1AI — one switchable input by jumper J2, accept corresponding analog signal by current 4...20 mA or voltage 0...10 V for frequency setting;
• 1DO — one multifunctional digital output (relay), which can be used for ON-OFF output signal for operational status, frequency or timer counter achievement, step or cycle completion of PLC program;
• RS485 — serial port connector RS485 for integrating in industrial array of frequency inverter NL, controllers, industrial PCs, etc.

How to correctly choose a model of scalar three-phase inverter series SPLC-NLP1000 380V?

Since the output voltage of the SPLC-NLP1000-2R2G4 is 380 V, three-phase electric motors 220/380 V will need to be connected using the star winding scheme. The corresponding parameters for this connection are indicated on the motor's nameplate. The model of the frequency inverter should be selected so that the table values of the nominal current and power are greater than the motor parameters.
