Scalar frequency converter series SPLC-NLP1000-7R5G4

Connection diagram of the three-phase scalar frequency converter SPLC-NL1000-2R2G-4

Power circuit of SPLC-NLP1000-7R5G4 frequency converters:

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

Control circuit of SPLC-NLP1000-7R5G4:

• 4DI - four digital inputs, the function of which can be defined independently using menu selection. For example, a digital input can be used for start, forward run, reverse, stop commands, 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 increase/decrease of frequency, timer start, activating PID regulation, built-in controller program, etc.
• 1AI - one input that can be switched using jumper J2 and accept the corresponding analog signal at a current of 4...20 mA or voltage of 0...10 V to set frequency;
• 1DO - one multifunctional digital output (relay) that can be used for ON-OFF signal about operating state, frequency or timer counter achievement, step or PLC cycle completion;
• RS485 - RS485 serial port connector for inclusion in industrial set of NL frequency converter, controllers, industrial PCs, etc.

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

Since the output voltage of SPLC-NLP1000-7R5G4 is 380 V, three-phase electric motors 220/380 V must be connected using a "star" winding connection scheme. The parameters of the engine corresponding to these connections are indicated on its nameplate. The frequency converter model should be chosen so that the rating values of nominal current and power are greater than the engine parameters.
