 Pr.06-05 and Pr.06-08 determine the drive’s operating mode after over-torque is detected.
 Over-torque is detected according to the following method: if the output current exceeds the over-torque
detection level (Pr.06-06, default is 150%) and also exceeds the over-torque detection time (Pr.06-07,
default is 0.1 second), the keypad displays the fault code “OT1/OT2”. If using a multi-function output
terminal for over-torque detection, the output is ON. Refer to Pr.02-11–02-22 for details.
