Features
Applicable to high-torque, large-capacity equipment
The VF-AS1 lineup offers 400 V class models with capacities of up to 500 kW. These models are ideal for high-torque, large-capacity equipment such as cranes, hoists, mining machines, refrigerators, press machines, compressors and crushers.
The VF-PS1 inverter is a 400 V class model supporting a capacity range of up to 630 kW for large-capacity fan and pump applications.
Easy settings
The quick mode, activated by the EASY key, shows only the eight basic parameters, which makes it easy to select and set the parameters.
Communication and networks
These models support RS-486 communication as a standard feature, as well as the TOSHIBA protocol and Modbus RTU protocol.
Also, the use of communication options enables support of the main fieldbuses of DeviceNet, PROFIBUS DP and CC-Link.
Adopts
- Dedicated fan and pump functions (VF-PS1)
- Built-in output cutoff function compliant with safety standards (VF-PS1)
- Support of a rich set of options (common to VF-AS1 and VF-PS1)
Dedicated fan and pump functions (VF-PS1)
(VF-PS1)
The inverter features dedicated fan and pump functions, such as local/remote mode, PID control with direct/inverse characteristic switching and fire control.
Built-in output cutoff function compliant with safety standards (VF-PS1)
(VF-PS1)
The power removal function (safety function) cuts off the output in compliance with the safety standard for the equipment.
- Compliant with ISO 13849-1 Category 3.
- Compliant with EN 60204-1 Stop Category 0 or 1.
- Compliant with IEC/EN 61508 SIL3.
- Compliant with the EC directive regarding explosion protection (ATEX Directive).
Support of a rich set of options (common to VF-AS1 and VF-PS1)
Dedicated options for VF-AS1 and VF-PS1 are available. For details, contact us.
Performance
- Advanced energy-saving mode (VF-PS1)
- Reduction in harmonic noise
- Suppression of harmonics and improvement in the power factor
Advanced energy-saving mode (VF-PS1)
The motor efficiency degrades in a low-speed range with a light load.
Control the motor so as to maximize its efficiency even in the low-speed range where the efficiency tends to degrade. This provides a greater energy-saving effect for fans and pumps.
Reduction in harmonic noise
The 400 V class models have a built-in EMC noise filter. The filter reduces harmonic noise substantially, and the inverter achieves compliance with the EU EMC Directive by itself.
Suppression of harmonics and improvement in the power factor
The accompanying or optional DC reactor suppresses harmonics while keeping the input current within 110% of the rated output current. This design is friendly to the power system, including the transformer, no-fuse breaker and wires.
