4.12 Monitor display and monitor output signal
4.12.1 Speed display and speed setting (Pr. 37, Pr. 144, Pr. 505)
The above parameter can be set when Pr. 160 Extended function display selection = "0". (Refer to page 197)

Performing IPM parameter initialization sets back the settings to the initial settings. ( Refer to page 85 )

Performing IPM parameter initialization changes the settings. ( Refer to page 85 )

The maximum value of the setting range differs according to the Pr. 1 Maximum frequency (Pr. 18 High speed maximum frequency) , and it can be calculated from
the following formula.
Note that the maximum setting value of Pr. 37 is 9998 if the result of the above formula exceeds 9998.

If Pr. 999 Automatic parameter setting setting is set to "20" or "21" while the machine speed is displayed ( Pr.37

0), calculate the rotations per minute based on
the changed
Pr.505
setting, and set
Pr.37
again. (
Refer to page 273
)
 To display a machine speed, set
Pr.37
to the machine speed at the frequency set in
Pr. 505
, and set
Pr. 144
to the number of
motor poles (2, 4, 6, 8, 10).
For example, when
Pr. 505 = "60Hz" and Pr. 37 = "1000", "1000" is displayed on the machine speed monitor at the running
frequency of 60Hz. When running frequency is 30Hz, "500" is displayed.
 When displaying the motor speed, set the number of motor poles + 100 (102, 104, 106, 108, 110) to
Pr. 144
.
 When both Pr. 37 and Pr. 144 have been set, their priorities are as given below.
Pr. 144 , 102 to 110

Pr. 37 , 1 to 9998

Pr. 144 , 2 to 10
 A combination of the Pr.37 and Pr. 144 settings determines the monitored item and the setting increment as shown in the
table below. (Initial settings are outlined with bold borders)

For Pr. 144 in the above formula, the value is " Pr. 144 -100" when "102 to 110" is set in Pr. 144 and the value is "4" when Pr. 37 = 0 and Pr. 144 = 0.
Pr. 505 is always set as frequency (Hz).
