to motor speed.
To change the item monitored on the
operation panel
To change the monitor item whose
data is output via terminal FM or AM
To adjust the output via terminal FM
or AM
To check the effects of energy saving Energy saving monitoring
To assign functions to the output
terminals
To detect the output frequency
To detect the output current
To detect the output torque
To use the remote output function
11.1

*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.
