This parameter determines the direction of motion for the multi-speed Pr.17 to Pr.23 and
Master Frequency. The original direction of Master Frequency will become invalid.
Note: A 7-bit binary number is used to program the forward/reverse motion for each of the 8
speed steps (including Master Frequency). The binary notation for the 7-bit number must
be translated into decimal notation and then entered in Pr.79.

Identity Code of the AC Motor Drive
Factory Setting: ##
Settings Read
Only
This parameter displays the identity code of the AC motor drive. The capacity, rated
current, rated voltage and the max. carrier frequency relate to the identity code. Users can
use the following table to check how the rated current, rated voltage and max. carrier
frequency of the AC motor drive correspond to the identity code.
