Connection diagram of the three-phase scalar inverter SPLC-NL1000-200G4

Power circuit of frequency inverters SPLC-NL1000-200G4:

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

Control circuit SPLC-NL1000-200G4:

• 4DI — four digital inputs, which can be self-determined via menu options. For example, a digital input can be used for start command, forward run, reverse, stop, frequency jump JOG, switching between frequency sources X and Y, switching between 16 preset speed frequency values, switching between 4 acceleration and deceleration modes, remote increase/decrease of frequency, timer start, PID control, embedded controller program, etc.
• 1AI — one input, switchable via jumper J2, to receive the corresponding analogue 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 regarding operating state, frequency or timer event, completion of a step or PLC program cycle;
• RS485 — RS485 serial port connector for integrating into industrial control systems of frequency converter NL, controllers, industrial PCs, etc.

How to choose the right model of scalar three-phase inverter series SPLC-NL1000 380V?

Since the output voltage SPLC-NL1000-200G-4 is 380 V, the three-phase motors 220/380 V need to be connected using the star winding connection method. The appropriate parameters for these connections are listed on the motor's nameplate. The model of the frequency inverter should be selected so that the nominal current and power table values are greater than the motor parameters.
