Speed Limit (Frequency Reference Limit
Function)
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 parameter d2-01.
Set the upper limit value of the Drive output frequency as a percent, taking E1-04 (Maximum Output Fre-
quency) to be 100%.

Limit
Determines maximum frequency
reference, set as a percentage of
maximum output frequency
(E1-04). If the frequency
reference is above this value,
actual Drive speed will be limited
to this value. This parameter
applies to all frequency reference
sources.
