Operation At Fault - Mitsubishi Electric A800-E Instruction Manual

(D) Operation command and frequency command

The operation is as set in Pr.338 Communication operation command source and Pr.339 Communication speed command source. (Refer
to the Instruction Manual (Detailed) of the FR-A800/FR-F800 inverter.)

At occurrence of communication error, the inverter cannot be reset.

Enabled only when stopped by the PU. "PS" is displayed on the operation panel for the PU stop. The operation is as set in Pr.75 Reset
selection/disconnected PU detection/PU stop selection. (Refer to the Instruction Manual (Detailed) of the FR-A800/FR-F800 inverter.)

Writing of some parameters may be disabled by the Pr.77 Parameter write selection setting and the operating condition. (Refer to the
Instruction Manual (Detailed) of the FR-A800/FR-F800 inverter.)

Some parameters are write-enabled independently of the operation mode and command source presence/absence. Writing is also enabled
when Pr.77 = "2". (Refer to the Instruction Manual (Detailed) of the FR-A800/FR-F800 inverter.) Parameter clear is disabled.

Applicable when Pr.550 NET mode operation command source selection = "5" (Ethernet connector enabled), or Pr.550 NET mode
operation command source selection = "9999" with no communication option connected

Applicable when Pr.550 NET mode operation command source selection = "0 (communication option enabled)", or Pr.550 NET mode
operation command source selection = "9999" with communication option connected

The frequency can be set by multi-speed setting or input through terminal 4.

communication check time interval

The operation depends on the communication option setting.

In the PU JOG operation mode, the operation always stops when the PU is disconnected. The operation at a PU disconnection fault (E.PUE)
occurrence is as set in Pr.75 Reset selection/disconnected PU detection/PU stop selection.
