Scalar frequency converter series SPLC-NLP1000-0R75G4

Wiring diagram for the three-phase scalar frequency inverter SPLC-NLP1000-0R75G4

Power Circuit of SPLC-NLP1000-0R75G4 Frequency Converters:

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

Control Circuit of SPLC-NLP1000-0R75G4:

• 4DI — four digital inputs, whose function can be independently defined by menu selection. For instance, a digital input can be used for commands such as start, run forward, reverse, stop, JOG frequency skip, switching between frequency sources X and Y, switching between 16 preset speed frequencies, switching between 4 ramp up and down modes, remote frequency increase/decrease, timer start, enabling PID regulation, built-in controller program, etc.
• 1AI — one input, switchable by J2 jumper and capable of receiving a corresponding analog signal with a current of 4...20 mA or a voltage of 0...10 V to set the frequency;
• 1DO — one multifunctional digital output (relay), which can be used for ON-OFF output signal for operational state, frequency or time counter achievement, completion of a PLC program step or cycle;
• RS485 — RS485 serial port connector for industrial frequency inverter NL set, controllers, industrial PCs, etc.

How to choose the correct model of scalar three-phase frequency inverter series SPLC-NLP1000 380V?

Since the output voltage of SPLC-NLP1000-0R75G4 is 380 V, three-phase 220/380 V motors must be connected using the "star" winding connection scheme. The corresponding parameters of the motor for these connections are specified on its nameplate. The model of the frequency converter should be chosen such that the nominal current and power table values exceed those of the motor's parameters.
