Speed Limit
(Frequency Reference Limit Function)
This section explains how to limit the motor speed.
 Limiting Maximum Output Frequency
If the motor should not rotate above a given frequency, use parameter d2-01.
Set the upper limit value of the frequency reference as a percentage, taking E1-04 (Maximum Output Fre-
quency) to be 100%.

 Limiting Minimum Frequency
If the motor should not rotate below a given frequency, use parameters d2-02 or d2-03.
There are two methods of limiting the minimum frequency, as follows:
• Adjust the minimum level for all frequencies.
• Adjust the minimum level for the master speed frequency (i.e., the lower levels of the jog frequency, multi-
step speed frequency, and auxiliary frequency will not be adjusted).
