"A" Function
Description
nd
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 gain of the inverter,
range is 20. to 100.%
Sets voltage compensation gain
under automatic torque boost,
range is 0. to 255.
nd
2
Sets slip compensation
under automatic torque boost,
range is 0. to 255.

Three options; select codes:
00...Disable
01...Enable during stop
02...Frequency detection
The frequency at which DC
braking begins,
range is from the start frequency
(B082) 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%
Sets the duration for DC braking,
range is from
seconds
Two options; select codes:
00...Edge detection
01...Level detection
Level of DC braking force at
start, settable from 0 to 100%
