Toshiba VFNC3C-4015P inverter 1.5 kW 3-phase 380 V (VF-nC3)

VFNC3C-4015P is a Toshiba VF-nC3 inverter – simple, ultra-compact inverter for small machines. It controls 3-phase induction motors up to 1.5 kW from a 3-phase 380 V (400 V class) supply, with check EMC filter configuration by model.

Toshiba describes VF-nC3 as a simple, compact range for small machines. Vertically arranged main circuit terminals, like a distribution breaker, for fast and tidy wiring. V/f and sensorless vector control; set up with the dial and keys on the front panel.

Reading the code: VF-nC3 is the range; the digit after the dash is the voltage class (2 = 200 V, 4 = 400 V); the next three digits give the rating (1.5 kW); PL includes an EMC filter, PM does not. Size the drive by the rated current on the 380 V motor nameplate; for heavy starting (loaded conveyors, crushers, compressors) choose one size larger.

VF-nC3 features

• Toshiba describes VF-nC3 as a simple, compact range for small machines.
• Vertically arranged main circuit terminals, like a distribution breaker, for fast and tidy wiring.
• V/f and sensorless vector control; set up with the dial and keys on the front panel.
• Small footprint with side-by-side mounting to save panel space.
• Well suited to replacing older drives on conveyors, fans and small pumps.

Sizing and accessories

• A 1.5 kW drive suits 380 V motors up to 1.5 kW on standard loads; compare the drive rated current with the motor nameplate.
• For heavy starting, frequent reversing or panel temperatures above 40 °C, choose one size larger.
• For fast stops of high-inertia loads (large fans, centrifuges, cranes), fit a braking resistor of the recommended value.
• For long motor cables or several motors on one drive, ask TOVINA about output reactors and settings.
• Protect the input with a correctly rated breaker or fuses; do not switch an output contactor to start/stop the motor.

Installation and wiring

• Connect the supply to R/L1, S/L2, T/L3 and the motor to U/T1, V/T2, W/T3 – never apply mains to U, V, W.
• Earth the drive and motor; route signal cables away from power cables to reduce noise.
• Mount vertically with clearance above and below for cooling; sealed panels need a fan.
• After power-off, wait until the capacitors discharge (charge lamp off) before touching terminals.

Basic setup

• CMOd – run command source (panel keys or F/R terminals).
• FMOd – frequency reference source (dial, external potentiometer, 0 – 10 V / 4 – 20 mA, RS485).
• ACC / dEC – acceleration and deceleration times; UL / LL – upper and lower frequency limits.
• vL – base frequency per motor nameplate (50 Hz); tHr group – motor overload protection level from the rated current.
• See the TOVINA video below; TOVINA sets up the drive free of charge at handover.

Routine maintenance

• Clean dust from the heat sink and cooling fan; replace noisy or weak fans.
• Re-tighten power terminals after a period of operation; look for signs of overheating.
• Review the trip history to catch overcurrent, overvoltage and overheating early.
• Power up spare drives periodically to keep the capacitors in condition.
