A compact, space-saving new type of DC reactor is built into 200 V class 11 to 45 kW and 400 V 18.5 to 75 kW models. In addition to reducing harmonics, this reactor limits the input current to 110% of the rated output current, and it has been designed to be compatible with power supply systems containing transformers, molded-case circuit breakers, and power lines. Adding on the optional DC reactor enables compliance with IEC harmonics standards.
High-frequency noise is drastically reduced on models with built-in noise filters. Built-in noise filters are ideal for sites from commercial facilities and offices through to factories where attention must be paid to peripheral devices. Compared with filter not integrated models, space and wiring savings have been achieved by incorporating the filter in the panel. Also, models with built-in EMC noise filter comply with the European EMC Directive as individual inverter units.
European EMC Directive :
IEC/EN61800-3, 1st Environment, C2
IEC/EN61800-3, 2nd Environment, C3
200V class models, 0.4 to 7.5kW : EMI noise filter (complies with the European EMC Directive) built-in standard
200V class models, 11 to 45kW : Basic noise filter (not complies with the European EMC Directive) built-in standard
400V class models, 0.75 to 75kW : EMI noise filter (complies with the European EMC Directive) built-in standard
400V class models, 90 to 500kW : EMI noise filter (complies with the European EMC Directive) built-in standard
In the Quick mode, pressing the EASY key on the panel allows you to operate the inverter by eight basic parameters. When setting each of the functions, press the EASY key to move to the standard mode by one-touch operation. In this mode, you can access all parameters.
You can customize the Quick mode display, maximum of 32 target parameters are displayed to suit your specific setup requirements.
You can also use the EASY key as a panel/remote key to switch between panel and remote operation, and as a shortcut key to directly access any specific setup or display screen.
Side-by-side installation Side-by-side installation of inverters is possible up to the inverter’s total capacity. This allows effective utilization of space inside control panels. Heat sink can be installed outside of the panel as an option.
Removable control terminal board
A removable terminal board is used. This allows you to use the control wiring when replacing the inverter, which also makes maintenance easier. ON/OFF control of cooling fan
Temperature-based ON/OFF control reduces noise while the inverter is being stopped, saves energy and extends the cooling fan’s life. Monitoring of serviceable parts/alarm output
The expected replacement cycle of main circuit capacitors, capacitors on control board, and cooling fan is monitored, and an alarm is output when the cycle is reached.
Motor constants required for vector control can be easily set by auto-tuning to enable 1:120 speed control. Moreover, the VFAS1 also features a robust structure that is unlikely to be influenced by motor temperature.
On inverters provided with a sensor, high-torque operation of 200%*2 from zero velocity is possible, achieving a speed control range of 1:1000.
High-speed response frequencies of 40 Hz without sensor and 50 Hz with sensor are achieved respectively, to maintain fixed speed in response to sudden changes in load.
Modifying software enables high-frequency output up to 1000 Hz, which is ideal for spindle rotation of woodworking and metalworking machinery.
When a TOSHIBA standard 3-phase, 0.4 to 3.7 kW 4-pole motor are driven.
Brake sequence/light-load, high-speed functions The inverter has two built-in functions, the brake sequence function and light-load, high-speed function, as standard. The brake sequence function measures the timing with braking by an external motor to achieve smooth operation at start and stop of braking operation. The light-load, high-speed function automatically increases the speed when operating light loads according to the lifting load to improve conveyance efficiency. A learning function for setting and storing to memory required parameters while performing actual operations is also provided to facilitate adjustments.
Built-in transistor for dynamic braking
The VF-AS1 has a built-in transistor for dynamic braking up to 160 kW, which makes it ideal for lifting applications.
With “My function”, you can create programs containing up to 28 steps. This achieves logic operations and internal data operations. Parameters can also be set according to analog input and minimum-peak hold of analog outputs. For example:
(Ex.1) Inverter is automatically switched to commercial operation without the external sequence when the inverter is tripped.
(Ex.2) A signal is output when torque reaches 120% and frequency is 5 Hz.
(Ex.3) “Forward rotation operation,” “Preset-speed operation frequency 3” and “No.2 acceleration/deceleration” are simultaneously turned ON by input on a single terminal.
(Ex.4) The acceleration/deceleration time is changed dynamically by a voltage within the range 0 to 10 V.
RS-485 communications RS-485 communications is equipped as standard, and Modbus-RTU protocol is supported in addition to TOSHIBA protocol.
Use of communication options enables support of DeviceNet(*1), PROFIBUS and CC-Link(*2) and other main fieldbuses.
The PCM002Z(*3) communications software allows you to edit, monitor, and trace parameter data on a PC, enabling easier data management from inverter startup through to maintenance.
