"A" Function
Description
Two options:
Manual torque boost
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
Sets voltage gain of the
inverter, range is 20. to 100.%
Sets voltage compensation
gain under automatic torque
boost, range is 0. to 255.
nd
motor
Sets slip compensation gain
under automatic torque boost,
range is 0. to 255.
Three options; select codes:
Disable
Enable during stop
Frequency detection
The frequency at which DC
braking begins,
Range is from the start
frequency () to 60Hz
The delay from the end of
controlled deceleration to start
of DC braking (motor free
runs until DC braking begins),
range is 0.0 to 5.0 sec.
Level of DC braking force,
settable from 0 to 100%
