Usb Device Communication - Mitsubishi Electric FR-A820-00046 (0.4K) Instruction Manual

 Network number and station number setting (Pr.434, Pr.435)
• Enter the inverter network number in Pr.434 Network number (CC-Link IE).
• The setting range of Pr.434 is "0 to 255", but its active range is "1 to 239". The values out of the active range are invalid
because such values cannot be transmitted to the master station.
• Use Pr.435 Station number (CC-Link IE) to enter the station number of the inverter.
• The setting range of Pr.435 is "0 to 255", but its active range is "1 to 120". The values out of the active range are invalid
because such values cannot be transmitted to the master station.
NOTE
• Use different station numbers for different devices. (If different devices have the same station number, the communication
cannot be performed properly. If an error occurs due to a duplicated number, re-assign the station numbers, then reset the
master station and the inverter power.)
• Station numbers do not have to be consecutive numbers.
• The Pr.434 and Pr.435 settings are applied after an inverter reset or next power-ON.
 Frequency command with sign (Pr.541)
• By adding a sign to the frequency command value, the start command (forward/reverse rotation) can be inverted to start
operation
• The Pr.541 Frequency command sign selection setting is applied to the frequency command from RWw0.

NOTE
• When Pr.541 = "1" (with sign)
- When EEPROM write is specified by turning ON of RY22, write mode error (error code H01) will occur.
- When both RY21 and RY22 are turned ON, RY21 has precedence.
- When power is turned ON (inverter reset), the initial setting status of the sign bit is "positive" and the set frequency is 0 Hz.
(The motor does not operate at the frequency set before turning OFF the power (inverter reset).)
- When set frequency is written with the instruction code of HED or HEE, the sign of the frequency command is not changed.

5.15.8 USB device communication

A personal computer and an inverter can be connected with a USB cable. Setup of the inverter can be easily performed with
FR Configurator2.
The inverter can be connected easily to a personal computer by a USB cable.
