Connection Diagram of Three-Phase Scalar Frequency Converter SPLC-NLP1000-22G4

Power Circuit of Frequency Converters SPLC-NLP1000-22G4:

• Power supply from a three-phase network 3ph 380 V AC 50/60 Hz;
• Linear output voltage ranges from 0 to 380 V, and frequency ranges from 0.1 to 400 Hz;
• Allowable overload for 60 s - up to 150% of the rated current value (in continuous load operation mode)

Control Circuit SPLC-NLP1000-22G4:

• 4DI – four digital inputs, which can be defined by the user via the menu. For instance, a digital input can be used for start command, forward run, reverse, stop, JOG frequency skip, switching between frequency sources X and Y, switching between 16 preset speed frequency values, switching between 4 acceleration and deceleration modes, remote frequency increase/decrease, timer start, PID regulation activation, built-in controller program, etc.
• 1AI – one input that allows switching using the J2 jumper and can receive the appropriate analog signal via current 4...20 mA or voltage 0...10 V for setting the frequency;
• 1DO – one multifunctional digital output (relay) that can be used for the ON-OFF output signal on the operating status, achieving frequency or time counter, completion of a PLC program step or cycle;
• RS485 – RS485 serial port connector for industrial assembly of NL frequency converter, controllers, industrial PCs, etc.

How to Choose the Correct Model of Scalar Three-Phase Frequency Converter Series SPLC-NLP1000 380V?

Since the output voltage of SPLC-NLP1000-22G4 is 380 V, three-phase electric motors 220/380 V must be connected using the "star" connection scheme. The parameters corresponding to these connections are indicated on the motor's label. The frequency converter model must be chosen so that the rated current and power table values are greater than the motor parameters.
