The operation level is lowered according to the following calcula-
tion.
OP1= OP2 x VF/OF
OP1: Stall prevention operation level during acceleration in the
constant power output area
OP2: Stall prevention operation level during acceleration (No. 30)
VF: Maximum voltage frequency (No. 04)
OF: Output frequency

Automatic control of V/f ratio according to the load torque ensures
tripless operation and optimum output current. Normally, no
adjustment is necessary. Use this function especially when motor
capacity is smaller than Inverter capacity and torque is required.
