(M) Item and Output Signal for Monitoring
12.1
Speed indication and its setting change to
rotations per minute
The frequency monitored or set on the operation panel can be changed to the motor speed or the machine speed.
*1 Gr.1 and Gr.2 are the parameter initial value groups. (Refer to page 52 ).
*2 The setting ranges of Pr.1 (Pr.18), Pr.37, and Pr.505 are limited so that the following formula is satisfied.
Pr.1 (Pr.18) × Pr.37 / Pr.505 < 8388.607
The setting range of Pr.1 (Pr.18) is not limited when the machine speed display is not selected. To display the machine speed, set values which
satisfy the formula.
 Displayed unit switchover (Pr.37, Pr.53, and Pr.505)
• The rotation speed or machine speed can be displayed for monitoring or used for parameter setting instead of the
frequency by using Pr.53 .
Purpose Parameter to set Refer to page
To display the motor speed (the
number of rotations per minute).
To switch the unit of measure to set
the operation speed from frequency
to motor speed.
