Speed Limit (Frequency Reference Limit Func-
tion)
This section explains how to limit the motor speed.
Limiting Maximum Output Frequency
If you do not want the motor to rotate above a given frequency, use constant d2-01.
Set the upper limit value of the Inverter output frequency as a percent, taking E1-04 (Maximum Output Fre-
quency) to be 100%.

Limiting Minimum Frequency
If you do not want the motor to rotate at below a given frequency, use constants d2-02.
Set the upper limit value of the Inverter output frequency as a percent, taking E1-04 (Maximum Output Fre-
quency) to be 100%.
