Example 7: This example is a combination of the previous 6 examples with forward and
reverse motion added. Note: forward and reverse motion control is not available through
the external terminals. (Refer to Pr.38-42 and Parameter values d00, d01, d02.)
Example 8: In this example sensors are used to control the output frequency from 60 to
0 Hz. As the process signal increases from 4 to 20 mA, the output frequency decreases
from 60 to 0 Hz.

Factory Setting d100%
Units 1%
Parameter value d30 - d120%
This parameter must be set according to the ampere specification found on the motor
nameplate. The setting will limit the AC drive output current and prevent the motor from
overheating. In the event the motor current exceeds this value, the output frequency will
be reduced until the motor current drops below this limit.
