When the Jogging Stop Selection (A039) is set to 03, 04, or 05, jogging operation will occur even if the
FW signal turns ON first.
However, if the JG signal turns OFF first, the motor will make a free-run stop.
• The torque boost function compensates for the voltage drop caused by the primary resistance in the
motor or by wiring to suppress torque reduction at a low speed range.
• To select Automatic torque boost in the 1st/2nd Torque Boost Selection(A041/A241), set the 1st/2nd
Motor Capacity (H003/H203) and the 1st/2nd Motor Pole Number (H004/H204) according to your
motor.
• By factory setting, the automatic torque boost option is selected.
