"A" Function
Description
Two options:
Manual torque boost
nd motor
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%
Four available V/f curves;
Constant torque
Reduced torque (1.7)
Free V/F
Sensorless vector (SLV)
Sets voltage
inverter, range is 20. to 100.%
Sets voltage
gain under automatic torque
boost, range is 0. to 255.
