10.5 Checking in the simulation mode
• Want to check a terminal without letting the inverter
outputs.
• Want to perform a simulative operation check by
giving an operation command without outputting.
• If the simulation mode [PA-20] is set to 01 and the
power is turned on again, the inverter enters the
simulation mode and does not output to the motor.
• To cancel the simulation mode, set [PA-20] to 00
and then turn on the power again.
• Because the inverter behaves just like a normal
operation except that it cannot output to the motor,
you can check terminals and communication
operations.
• It will be possible to change the internal data on a
real-time basis by assigning a parameter or analog
input to the internal data.
• Operation checks can be performed in the condition
that the control power supply is input or 24-V power
supply is used.
• If the error code selection [PA-21] is set during the
simulation mode, a trip is issued as soon as the
setting is made. To cancel a trip, reset the inverter
(turn ON the [RS] terminal or press RESET key) as
usual. When the inverter is reset, [PA-21] will be
automatically set to 00.
Entering the simulation mode
Set the simulation mode [PA-20] to 01.
Turn off the power, and then turn it on again.
The simulation mode becomes active.
• The motor cannot be driven in the simulation mode.
• To check the actual motor behavior, set the
simulation mode [PA-20] to “00: Disable” and then
turn on the power again.
• To activate the simulation mode, activate it in the
condition that 24-V power supply is input for 24-V
power supply; that control power supply is input for
control power supply terminals (R0, T0) inputs; and
that R, S, and T terminals are input for main power
supply inputs R, S, and T. Then turn off the power
to end the simulation mode.
• Because the simulation mode is for simulating
terminals’ behaviors, the function activated by a
motor control operation does not work.
• In the simulation mode, if an error not listed in the
selection of error code for alarm test [PA-21] is
entered, the error will not be generated.
• In the simulation mode, if a serious fault error is
entered to the selection of error code for alarm test
[PA-21], the power needs to be turned on again.
(Serious fault errors: E010, E011, E014, E019,
E020)
Canceling the simulation mode
Set the simulation mode [PA-20] to 00.
Turn off the power, and then turn it on again.
The simulation mode is canceled.
