The wide range of functions of the VF-nC1 meets various users' needs from simple speed control to steady torque at low speed.

Excellent Motor Control

• High torque

  Sensor less vector control provides string, stable torque characteristic from the start of a motor to the rated rotation speed.
  You just enter the values on the name plate of a motor, and set the motor parameters by auto-tuning function.

• Energy-Saving mode

  Energy-saving mode enable to reduce energy consumption for fans and pumps.

Long Lifetime

• Designed for 10 years of operation

  The main-circuit capacitors, a cooling fan and control-board capacitors are designed for long life to achieve design lifetime of 10 years.
  (Conditions: Average annual ambient temperature = 40°C output current = 80% of the rated current: 24 hors / 365 days. The designed lifetime is calculated value, not guaranteed one.)
  The cooling fan is automatically turned on and off to further prolong the lifetime.

• Monitors when to replace major parts

  The VF-nC3 has the function to monitor and output warning when to replace major parts and keep track of the cumulative operation time.

Safety Features

• Protects the setting parameters

  The VF-nC3 provides protection for the setting parameters. For enhanced security, you can use a four-digit password.
  The VF-nC3 has a feature for saving and restoring a set of parameters.

Eco Design

• Compliant with the European RoHS Directive
• Built-in noise filters to suppress electromagnetic noise

  The single-phase 240V model have built-in EMC noise filter comply with the European EMC Directive to reduce radio-frequency noise from the inverter.
  This saves space and wiring, compared to using an external noise filter.

  Single-phase 240V model: European EMC Directive IEC/EN 61800-3 1st Environment, C1
