Limit Frequency and Operation Commands

A limiter of the upper and lower limits of the frequency command can be set. The upper limiter can be
set from analog input by setting [bA101].
This function limits a frequency command even if a frequency command value outside the range
between the upper and lower limiters is set.
Precautions for Correct Use
• The upper and lower limiters should be set lower than the maximum frequency. Otherwise,
warning of the inconsistency will arises.
• To set the limiters, set the upper limiter [bA102] first. Make sure that it is larger than the lower
limiter value [bA103].
• Under the restriction by the upper and lower limiters and the minimum frequency, a LIM icon
appears.
• To enable Upper Frequency limit [bA102], set [bA101] = 07: Parameter setting.
