Description Stop Mode (CFN15) set to Voltage Deceleration:
The voltage deceleration profile utilizes an open loop S-curve voltage ramp profile. The Decel End Level
parameter sets the ending voltage level for the voltage deceleration ramp profile. The deceleration ending
level is not a precise percentage of actual line voltage, but defines an ending point on the S-curve deceleration
profile.
A typical voltage decel end level setting is between 10% and 20%. If the motor stops rotating before the
deceleration time has expired, increase this parameter value. If the motor is still rotating when the
deceleration time has expired, decrease this parameter value. If the value is set too low a “No Current at Run”
fault may occur during deceleration.

NOTE: The deceleration end level cannot be set greater than the decel begin level.
Stop Mode (CFN15) set to TruTorque Deceleration:
The decel end level parameter sets the ending torque level for the TruTorque deceleration ramp profile.
A typical TruTorque decel end level setting is between 10% and 20%. If the motor stops rotating before the
deceleration time has expired, increase this parameter value. If the motor is still rotating when the
deceleration time has expired, decrease this parameter value.
