Entering The Start Signal And Multi-Speed Signal From Outside And Setting Multiple Speeds From The Parameter Unit - Mitsubishi Electric FR-PU04 Instruction Manual

Combined Operation (Operation Using External Input Signals and PU)
4.3.3 Entering the start signal and multi-speed signal from outside and
setting multiple speeds from the parameter unit
Step Operation Procedure
1
Switch the power ON.
2 Select the multi-speed
signal required for
operation.
Switch the RH, RM or RL
signal ON.
3 Set the start switch (STF
or STR signal) to ON.
The operation command
indication changes to "STF"
or "STR", the operation
status indication changes to
the output (FWD or REV)
indication, and the motor
starts running.
· If the forward and reverse
rotation switches are both set to
ON, the inverter will not start.
Also, if these switches are both
set to ON during operation, the
motor is decelerated to a stop.

Operation Procedure
4 Change the multi-speed
frequency during
operation from the
parameter unit.
When high speed has been
selected (RH signal ON),
changing the Pr. 4 Multi-speed
setting (high speed) value
varies the speed.
·The other multiple-speed
settings not being used may
also be changed during
operation.
5 Switch off the multi-speed
signal (RH, RM or RL
signal) and set the start
switch (STF or STR
signal) to OFF.
The motor stops running.
