5–17 Programming
[Stop Select 2]
This parameter selects the stopping mode when the
drive receives a valid stop command unless
[Stop Select 1] is selected.
Parameter Number 52
Parameter Type Read and Write
Factory Default “Coast”
Units Display Drive
“Coast” 0
Causes the drive to turn off immediately.
“DC Brake” 1 Injects DC braking voltage into the motor.
Requires a value in both [DC Hold Time]
& [DC Hold Level].
“Ramp” 2 Drive decelerates to 0 Hz, then if [DC
Hold Time] & [DC Hold Level] are greater
than zero the holding brake is applied. If
the values equal zero, then the drive
turns off. Requires a value in [Decel Time
1] or [Decel Time 2].
“S Curve” 3 Drive causes S Curve Ramp to 0 Hz in
[Decel Time 1] or [Decel Time 2] x 2.
[KI Amps]
Sets the integral gain for the current limiting function
of the drive. Default values are chosen for high
inertia loads. If faster accel is required, raising the
gain will allow additional current to the motor.
Excess gain settings may create unstable operation.
Important: [KP Amps] should be adjusted in equal
proportion or unstable operation may occur.
Parameter Number 192

Display Units / Drive Units NA / NA
Factory Default 100
Minimum Value 25
Maximum Value 800
[KP Amps]
Sets the proportional gain for the current limiting
function of the drive. Default values are chosen for
high inertia loads. If faster accel is required, raising
the gain will allow additional current to the motor.
Excess gain settings may create unstable operation.
Important: [KI Amps] should be adjusted in equal
proportion or unstable operation may occur.
