Connection diagram of the three-phase scalar frequency converter SPLC-NLP1000-3R7G4

Power Circuit of SPLC-NLP1000-3R7G4 Frequency Converters:

• Powered from a three-phase 3-phase 380 V AC network 50/60 Hz;
• Linear output voltage ranges from 0 to 380 V, and frequency ranges from 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-NLP1000-3R7G4:

• 4DI — four digital inputs, the function of which can be defined by menu selection. For example, a digital input can be used for a 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, enabling PID control, built-in controller program, etc.
• 1AI — one input that can be switched using jumper J2 and accept an appropriate analog signal via current 4...20 mA or voltage 0...10 V for frequency setting;
• 1DO — one multifunctional digital output (relay) that can be used for ON-OFF output signal about operating status, frequency or counter achievement, step or PLC program cycle completion;
• RS485 — RS485 serial port connector for industrial networking of NL frequency converters, controllers, industrial PCs, etc.

How to select the correct model of SPLC-NLP1000 380V series three-phase scalar converter?

Since the output voltage of SPLC-NLP1000-3R7G4 is 380 V, three-phase motors 220/380 V must be connected using the star connection scheme. The parameters corresponding to these connections are indicated on the motor's nameplate. The frequency converter model should be chosen so that the tabular values of the nominal current and power are higher than the motor's parameters.
