Switching of PU, External, and NET operation modes can be performed during operation.
External operation mode (PU operation interlock)
X12 signal ON: Switchover to PU operation mode enabled (during External operation, output

shutoff)
X12 signal OFF: Switchover to PU operation mode disabled
*1 The priorities of the frequency commands while Pr.79 = "3" are "Multi-speed operation (RL/RM/RH/REX) > PID control (X14) > terminal 4 analog
input (AU) > digital input from the operation panel".
 Operation mode basics
• The operation mode specifies the source of the start command and the frequency command for the inverter.
• Basically, there are following operation modes.
External operation mode:
PU operation mode :
Network operation mode :
(NET operation mode)
