R/W Description
R/W Define how end of jog stops
the motor; three options:
00 .. Free-run stop
01 .. Controlled deceleration
02 .. DC braking to stop
R/W Can boost starting torque
between 0 and 20% above
normal V/f curve,
R/W
range is 0.0 to 20.0%
R/W Sets the frequency of the V/f
breakpoint A in graph (top of
previous page) for torque
R/W
boost, range is 0.0 to 50.0%
R/W Two available V/f curves;
three select codes:
00 .. Constant torque
R/W
01 .. Reduced torque
02 .. Intelligent sensorless
vector control
R/W Sets voltage gain of the
inverter, range is 20. to 100.%
R/W Sets torque boost voltage gain
of the inverter,
range is 0 to 255
R/W
R/W Sets torque boost slip gain of
the inverter,
range is 0 to 255
R/W
R/W Two options; select codes:
00 .. Disable
01 .. Enable
R/W The frequency at which DC
braking begins,
range is from the start
frequency (B082) to 60 Hz
R/W 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.
