"A" Function
Description
Two options:
00...Manual torque boost
motor
nd
01...Automatic torque boost
Can boost starting torque
between 0 and 20% above
normal V/f curve,
range is 0.0 to 20.0%
Sets the frequency of the V/f
breakpoint A in graph (top of
previous page) for torque
boost,
range is 0.0 to 50.0%
Six available V/f curves;
00...Constant torque
01...Reduced torque (1.7)
02...Free V/F
03...Sensorless vector (SLV)
Sets voltage
inverter, range is 20. to 100.%
Sets voltage
gain under automatic torque
boost, range is 0. to 255.
