run) is set to 0(No), a command through the input terminals will work ONLY AFTER all the
terminals listed above have been turned off and then turned on again.
• If the inverter has been reset to clear a fault trip during an operation, the inverter will switch to
local operation mode at power-on, and full control of the inverter will be with the keypad. The
inverter will stop operating when operation mode is switched from “local” to “remote”. In this case,
a run command through an input terminal will work ONLY AFTER all the input terminals have
been turned off.
Inverter Operation During Local/Remote Switching
Switching operation mode from “remote” to “local” while the inverter is running will cause the inverter
to stop operating. Switching operation mode from “local” to “remote” however, will cause the inverter to
operate based on the command source:
• Analog commands via terminal input: the inverter will continue to run without interruption based
on the command at the terminal block. If a reverse operation (Rx) signal is ON at the terminal block
at startup, the inverter will operate in the reverse direction even if it was running in the forward
direction in local operation mode before the reset.
• Digital source commands: all command sources except terminal block command sources (which
are analog sources) are digital command sources that include the keypad, LCD keypad, and
communication sources. The inverter stops operation when switching to remote operation mode,
and then starts operation when the next command is given.
Use local/remote operation mode switching only when it is necessary. Improper mode switching may
result in interruption of the inverter’s operation.
4.7 Forward or Reverse Run Prevention
The rotation direction of motors can be configured to prevent motors to only run in one direction.
Pressing the [REV] key on the LCD keypad when direction prevention is configured, will cause the
motor to decelerate to 0Hz and stop. The inverter will remain on.
