Other Motor Control Mode Parameters
The table below lists other parameters that may need to be adjusted, depending on the setting of parameter
[Mot cont. mode sel.] (Pt).
Relationship Between [Mot cont. mode sel.] (Pt) setting and Other Motor Parameters
X: Not applicable for the [Mot cont. mode sel.] (Pt) setting
⊗: Adjustment of this parameter is required.
O: Adjust this parameter if necessary.

Low speed motor torque can be adjusted with parameter ub when parameter [Mot cont. mode sel.] (Pt) (see page 67) is set
to 0 (Constant V/Hz) or 1 (Variable Torque). See curves on page 66
for more information.
If nuisance overcurrent faults occur during starting, reducing the setting of parameter ub may help.
