Speed Limit (Frequency Reference Limit Func-
tion)
This
section explains how to limit the motor speed.
K K K K
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 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 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).
