4.13 Monitor Display And Monitor Output Signal; Speed Display And Speed Setting (Pr.37, Pr.144) - Mitsubishi Electric FR-E700EX Instruction Manual

4.13 Monitor display and monitor output signal

Purpose
To display motor speed
To set speed
To change PU monitor display data
To change the monitor output from
terminal FM
To set the reference of the monitor
output from terminal FM
To adjust terminal FM outputs

4.13.1 Speed display and speed setting (Pr.37, Pr.144)

The increments of the motor speed and the monitored items displayed on the operation panel and PU (FR-PU07) can
be switched among frequency, machine speed, etc.

The above parameters can be set when Pr.160 Extended function display selection = "0". (Refer to page 182)

The maximum value of the setting range differs according to the Pr.1 Maximum setting and it can be calculated from the following formula.
Maximum setting value of Pr.37
Note that the maximum setting value of Pr.37 is 9998 if the result of the above formula exceeds 9998.
 To display a machine speed, set the machine speed at 3000r/min in Pr.37, and set the number of motor poles (2, 4, 6, 8, 10)
in Pr.144.
For example, when Pr.37 = "1000", "1000" is displayed on the speed and set speed monitor when the running speed is
3000r/min. When running speed is 1500r/min, "500" is displayed.
 When the number of motor poles +100 (102, 104, 106, 108, 110) is set in Pr.144, values are displayed in motor speed
increments. (When Pr.37 = "0")
 To change the display increments to frequency, set the number of motor poles (10) in Pr.144. (When Pr.37 = "0")
 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)
