resolution depends on the rated output current after the Drive
Duty has been set in parameter C6-01.
Sets a time constant filter for output power detection.
kW Filter Time
Sets the limit for the voltage search operation as a percentage
Search V Limit of the motor rated voltage.
Coefficient to adjust torque linearity.
Set to the Ki value on the motor nameplate.
PM Enrgy Save Ki When parameter E5-01, Motor Code Selection (for PM
Motors), is set to 1ooo or 2ooo, the automatically
calculated value will be set. This set value cannot be changed.
Coefficient to adjust torque linearity.
Set to the Kt value on the motor nameplate.
PM Enrgy Save Kt When parameter E5-01, Motor Code Selection (for PM
Motors), is set to 1ooo or 2ooo, the automatically
calculated value will be set. This set value cannot be changed.
Sets a compensation method for the q-Axis current when output
voltage is limited.
There is normally no need to change this parameter from the
Iq Comp Method
default value.
