PARAMETERS
<Setting>
Refer to the following list and set the parameters.
* : When Pr. 59 = "1" or "2", the functions of the RL, RM and RH signals change as
listed above.
**: Activated when the relay contact "opens".

**
The external thermal relay provided for overheat
protection or the embedded temperature relay
within the motor is activated to stop the inverter.

15-speed selection (combination with three
speeds of RL, RM, RH)
Pr. 4 to Pr. 6,
Pr. 24 to Pr. 27,
Pr. 232 to Pr. 239
16 X16 PU operation-external operation switch-over Pr. 79
18 X18
General-purpose magnetic flux vector-V/F switch-
over (OFF: general-purpose magnetic flux vector
control, ON: V/F control) (Note 3)
Pr. 80
Note:1. One function can be assigned to two or more terminals. In this case, the
terminal inputs are OR' ed.
2. The speed command priorities are higher in order of multi-speed setting
(RH, RM, RL, REX) and AU.
3. When V/F control is selected using the V/F-general-purpose magnetic flux
switch-over function, the secondary functions are also selected.
During operation, you cannot switch between V/F and general-purpose
magnetic flux. Should you switch between V/F and general-purpose
magnetic flux, only the second functions are selected.
4. Use common terminals to assign multi-speeds (7 speeds) and remote
setting. They cannot be set individually.
(Common terminals are used since these functions are designed for
multiple speed setting and need not be set at the same time.)
5. Functions are invalid if values other than the above are set to Pr. 180 to Pr.
183 (input terminal function selection).
6. Turning the AU signal on makes voltage input invalid.
