(D) Operation command and frequency command
12
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.
Operation at fault
Selectable with
Pr.75 Reset selection/disconnected PU detection/PU stop selection
Selectable with
Pr.122 PU communication check time interval, Pr.548 USB communication check time interval,
and
Pr.1432 Ethernet
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
.
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
