Connection Diagram of Three-phase Scalar Inverter SPLC-NLP1000-18.5G4

Power Circuit of SPLC-NLP1000-18.5G4 Frequency Converters:

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

Control Circuit of SPLC-NLP1000-18.5G4:

• 4DI — four digital inputs, whose function can be independently defined using selection in the menu. For example, a digital input can be used for start, forward run, reverse, stop, jog frequency skipping, 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 control activation, built-in controller program start, etc.
• 1AI — one input, which can be switched using a jumper J2 to accept a corresponding analog signal via current 4...20 mA or voltage 0...10 V to set the frequency;
• 1DO — one multifunctional digital output (relay), which can be used for ON-OFF output signal of operating status, frequency or timer counter achievement, program cycle or step completion of the PLC;
• RS485 — RS485 serial port connector for industrial frequency converter NL, controllers, industrial PCs, etc.

How to Choose the Right Model of Scalar Three-phase Inverter Series SPLC-NLP1000 380V?

Since the output voltage of SPLC-NLP1000-18.5G4 is 380 V, the three-phase motors 220/380 V will need to be connected by winding connections in a "star" configuration. Corresponding parameters of these connections are indicated on the motor's nameplate. The model of the frequency inverter should be chosen so that the table values of rated current and power are greater than those of the motor.
