Hello,

 The most exclusive model of Toshiba inverter series
  VF-PS1 VFD speed controller


   Toshiba inverter VF-PS1 Wide power range
   The VF-PS1 is available in a wide power range, up to 630 kW for 400V three-phase models.
There are versions for the three-phase supply of 230V, with the current power range 0.4 - 90KW.

   Functions:
   All this is required only access. V/f scalar control, variable torque, sensorless or close-loop vector, torque limit. HGH level functions are built for automatic running cycle, logic function programmability (MY Function), fan and pumps control. 

   In addition, you can find extensive information about dual mode (standard and type) speed, 4 independent sets of motor parameters, oscilloscope function monitoring block PID, and other optional cards from the links below.

   Solutions for harmonics;
   Built for all models with DC reactor power equal to or greater than 18.5KW. Reducing harmonic current distortion and inverter efficiency increase. EMC filters are built on all sizes.
IP54 type protection
   PS1 has an IP54 off design available for all 400V VF-up 90KW inverters.

  Parameter access and setting is no problem with Easy Key
  Easy Key for direct access to the specified parameters hierarchy.

   Free spin, Standard default setting for free stop. To free spin the motor, assign a terminal function "1(ST)" using the programmable terminal function. Set it to f110=0. For freewheeling, turn on the ST-CC when you stop the engine in the state described on the left. At this time on the monitor on the driver.

   An attempt was made to assign a value higher than the programmable range. Or as a result of changing other parameters, the programmed value of the now selected parameter exceeds the upper limit.

   An attempt was made to assign a value lower than the programmable range. Or as a result of changing other parameters, the programmed value of the now selected parameter exceeds the lower limit. If the above alarm is flashing, it cannot be adjusted with values ​​greater than or equal to “HI” or less than or equal to “LO”.

   Basic parameters that must be programmed before first use. : Parameters that require detailed and special adjustment. (Indicates parameters that are different from the standard default setting parameters. Use these parameters to check or change the setting after the setting. (Parameter title: gr.u ) This parameter has the function of displaying the five most recently changed parameters in reverse chronological order. This function can display the same parameter in reverse chronological order. It is very useful when you repeatedly set the driver using

• (Local/remote) Near / Far mode

You can easily switch from keypad or terminal to control with a single touch. As the Remote Local (Bumpless function) transition, the operating frequency and status are shifted to Local mode. In this way, both parameter and control interventions can be made faster.

• Fire and Emergency control
It has a special input for fire or emergency situations, in such a case the inverter continues to work non-stop and continues to work by ignoring environmental faults.

• Multi-PID function
Inversely proportional to PID operating pressure, flow and temperature can be changed directly.

• Sleep function (auto stop function)
Additional energy savings can be achieved by stopping as a lower limit setting

• Low torque detection function
To avoid low torque sensing pump trouble, you may notice a broken belt on the AHU or low load.

• PTC thermistor input
This function is used to protect the motor from overheating using PTC signal onboard motor.
