Automatic Torque Boost (Pr. 38, Pr. 39); Up-To-Frequency Sensitivity (Pr. 41) - Mitsubishi FR-F500 Instruction Manual

4.2.18 Automatic torque boost (Pr. 38, Pr. 39)

Pr. 38 "automatic torque boost"
Pr. 39 "automatic torque boost operation starting current"
Used to detect the load current to control the output voltage (torque) of the inverter automatically.

4.2.19 Up-to-frequency sensitivity (Pr. 41)

Pr. 41 "up-to-frequency sensitivity"
The ON range of the up-to-frequency signal (SU) output when the output frequency reaches the running
frequency can be adjusted between 0 and 100% of the running frequency.
This parameter can be used to ensure that the running frequency has been reached or used as the operation
start signal etc. for related equipment.
