Pu/External Combined Operation Mode 1 (Pr.79 = "3"); Pu/External Combined Operation Mode 2 (Pr.79 = "4"); Switchover Mode (Pr.79 = "6") - Mitsubishi Electric FR-F800 Instruction Manual

PU/External combined operation mode 1 (Pr.79 = "3")
• Select the PU/External combined operation mode 1 when applying a frequency command from the operation panel or the
parameter unit and inputting a start command with the external start switches.
• Set "3" in Pr.79. The mode cannot be changed to other operation modes.
• When a frequency is input from the external signal by multi-speed setting, it has a higher priority than the frequency
command from the PU. Also, when AU is set to "ON", the command signal is output to the terminal 4.

PU/External combined operation mode 2 (Pr.79 = "4")
• Select the PU/External combined operation mode 2 when applying a frequency command from the external potentiometer,
or multi-speed and JOG signals, and inputting a start command by key operation of the operation panel or the parameter
unit.
• Set "4" in Pr.79. The mode cannot be changed to other operation modes.

Switchover mode (Pr.79 = "6")
• PU, External and Network operation (when RS-485 terminals or communication option is used) can be switched among
during operation.

Operation switchover/Operating status
Set to the PU operation mode on the operation panel and the parameter unit.
• As the direction of rotation, the direction that was active by External operation is continued.
• For the setting frequency, the setting of the potentiometer (frequency command) is continued. (Note,
however, that the setting disappears when the power is turned OFF or when the inverter is reset.)
The switchover command to the Network operation mode is transmitted via communication.
• As the direction of rotation, the direction that was active by External operation is continued.
• The setting by the setting potentiometer (frequency command) is kept. (Note, however, that the setting
disappears when the power is turned OFF or when the inverter is reset.)
Press the External operation key on the operation panel and the parameter unit.
• The direction of operation is determined by the External operation input signal.
• The setting frequency is determined by the external frequency command signal.
The switchover command to the Network operation mode is transmitted via communication.
• For the direction of operation and setting frequency, the status during PU operation is continued.
The switchover command to the External operation mode is transmitted via communication.
• The direction of operation is determined by the External operation input signal.
• The setting frequency is determined by the external frequency command signal.
Switch to the PU operation mode on the operation panel and the parameter unit.
• For the direction of operation and frequency, the status during Network operation is continued.
