182 DB Resistor Sel
Used to set percent duty cycle for external dynamic braking.
0 = Disabled Drive Advanced Setup
183 S Curve %
Sets the percentage of acceleration or deceleration time that is
applied to ramp as S Curve. Time is added, half at the beginning
and half at the end of the ramp.
0% (Disabled) Drive Advanced Setup
184 Boost Select
Sets the boost voltage (% of Parameter 131 (Motor NP Volts))
and redefines the Volts per Hz curve. Active when Parameter 225
(Torque Perf Mode) = 0 (V/Hz). Drive may add additional voltage
unless Option 5 is selected.
