10. (D) Operation Command and Frequency Command
10.3 Start command source and frequency command source during communication operation
*6 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 page 173 .) Parameter clear is disabled.
*7 At occurrence of communication error, the inverter cannot be reset.
*8 The inverter can be reset by using the multi-speed operation function and analog input (terminal 4).
 Operation when a communication error occurs
• Standard model
• Ethernet model / Safety communication model
*1 Selectable with Pr.75 Reset selection/disconnected PU detection/PU stop selection .
*2 Selectable with Pr.122 PU communication check time interval, Pr.548 USB communication check time interval, Pr.1431 Ethernet signal
loss detection function selection, Pr.1432 Ethernet communication check time interval, and Pr.1457 Extended setting for Ethernet
signal loss detection function selection
.
*3 In the PU JOG operation mode, 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 .
*4 The operation depends on the communication option setting.
 Selecting the command interface in the Network operation mode (Pr.338,
Pr.339)
• Selecting a command interface is required for the following two types of commands: the operation command using the start
signals and the signals related to the inverter function selection, and the speed command using signals related to the
frequency setting.
