Parameter overview

For simple variable-speed operation of the inverter, the initial setting of the parameters may be
used as they are. Set the necessary parameters to meet the load and operational specifications.
Parameter setting, change and check can be made from the operation panel.
indicates simple mode parameters. (initially set to extended mode)
The abbreviations in the explanations below are as follows:
V/F V/F V/F
AD MFVC AD MFVC AD MFVC
GP MFVC GP MFVC GP MFVC
Parameters without any indication are valid for all control. The half-tone screened parameters
allow its setting to be changed during operation even if "0" (initial value) is set in Pr. 77 "Pa-
rameter write selection".
