(4) Calibration of stall prevention operation level (
Pr. 406
= "4")
When
Pr. 406
= "4" under V/F control and Advanced magnetic flux vector control, terminal 6 acts as stall
prevention operation level and
Pr. 148
and
Pr. 149
are used for calibration parameter.
(5) Calibration of torque bias input (
Pr. 406
= "6")
When
Pr. 406
= "6", terminal 6 acts as torque bias input and
Pr. 846 to Pr. 848, C34 to C37
are used for
calibration parameter.
