The efficiency of induction motor normally fall at the light load and low speed.
The advanced energy-saving mode minimize the loss of induction motor by controlling excitation current belong to the load.
Therefore, this mode increase fan and pump efficiency even in the low speed.
The Energy saved power consumption can be monitored by operation panel or through serial communication data.
Built-in noise filters are ideal for site such as commercial facilities and offices where attention must be paid to peripheral devices.
Compared to filter not integrated models, space and wiring can be saved by incorporating filter in the panel.
Models with built-in EMC noise filter comply with the European EMC Directive as individual inverter units.
New types of compact and space-saving DC reactor is built-in for 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.
Optional DC reactor meets IEC harmonics standards.
Local/Remote mode
You can simply switch between Local and Remote by EASY key. By switching from Remote to Local (Bumpless function),
the operating frequency and status are shifted to Local mode. It is easier for operation and adjustment.
Fire control
Fire control keeps operation with specified speed even if light fault occurs.
Multi-PID function
The PID operation can be changed at direct and inverse proportion by pressure, flow and temperature.
Sleep function (automatic stop function)
Additional energy saving can be realized by stopping at lower limit setting
Low torque detection function
Low torque detection can notice a broken belt of AHU or low load to avoid pump trouble.
PTC thermistor input
This function is used to protect motor from overheating using the signal of PTC built-in motor.
In the Quick mode, pressing the EASY key on the panel allows you to operate the inverter by eight basic parameters.
When setting each functions, press the EASY key to switch 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 32target parameters are displayed to suit your specific setup requirements.
You can also use the EASY key as a Local/Remote key to switch between Local 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 is possible for all VF-PS1 models. You can save and optimize space inside of control panel.
Heat sink can be installed outside of the panel as an option.
Removable control terminal board
. A removable terminal board allows you to use the control wiring when replacing the inverter, which also makes
maintenance easier.
ON/OFF control of cooling fan
. Temperature-based cooling fan ON/OFF control reduces sound noise, saves energy, and extends the cooling fan's life.
Monitoring of serviceable service parts/alarm output
. The expected replacement cycle of main circuit capacitors, capacitors on control board, and cooling fan is monitored.
And alarm is raise when the cycle is reached to the expected replacement time

Customizing by "My Function" with Toshiba VF-PS1 inverter

Using "My function", you can create programs up to 28 steps. This achieves logic operations and internal data operations.
Parameters can also be set by analog input and minimum-peak hold of analog outputs.
For example:
(Ex.1) Inverter is automatically switched to commercial operation without 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.
