Adjustable 5 points V/F will not function under simple magnetic flux vector control.

When Pr. 19 Base frequency voltage = "8888" or "9999", Pr. 71 cannot be set to "2". To set Pr. 71 to "2", set the rated voltage value to Pr. 19

When the frequency values of the points are the same, a write

inhibit error ( ) occurs.

Set the points (frequencies, voltages) of Pr. 100 to Pr. 109 within the ranges of Pr. 3 Base frequency and Pr. 19 Base frequency voltage .

When “2” is set in Pr. 71, Pr. 47 Second V/F (base frequency) will not function.

When “2” is set in Pr. 71, thermal characteristic of the electronic thermal relay function changes to thermal characteristics of a standard motor.

(1)Initial settings and specifications of RS-485 communication (Pr.117 to Pr.124, Pr.331 to Pr.337, Pr.341)

Used to perform required settings for RS-485 communication between the inverter and personal computer.

￿There are two different communications: communication using the PU connector of the inverter and communication using the RS-485 terminals.

￿You can perform parameter setting, monitor, etc. using the Mitsubishi inverter protocol or Modbus-RTU protocol.

￿To make communication between the personal computer and inverter, initialization of the communication specifications must be made to the inverter.

Data communication cannot be made if the initial settings are not made or there is any setting error.

(2) Communication EEPROM write selection (Pr.342)

Options
