[Bus Limit En]
Enables the function that attempts to limit the drive
DC bus voltage to 110% of nominal voltage during
rapid decel. If bus voltage rises above the 110% level,
[BUS Limit En] reduces or stops the drive decel rate
until bus voltage falls below the 110% level.
Parameter Number 11
Parameter Type Read and Write
Factory Default “Disabled”
Units Display Drive
“Disabled” 0
Allow bus voltage to rise above
110%.
“Enabled” 1 Limit bus voltage/decel ramp.
[Motor Type]
This parameter should be set to match the type of
motor connected to the drive.
Parameter Number 41
Parameter Type Read and Write
Factory Default “Induction”
Units Display Drive
“Induction” 0
Requires no additional setting.
“Sync Reluc” 1 [Slip @ F.L.A.] must be set to zero.
“Sync PM” 2 [Stop Select 1 & 2] must be set to a
selection other than “DC Brake” and
[Slip @ F.L.A.] be set to zero.
[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.
“Ramp to Hold” 4 Drive decelerates to zero Hertz then
injects holding brake per [DC Hold Level]
(limited to 70% of drive rated amps) until
a) a Start command is issued or b) the
Enable input is opened.
[KI Amps] – Firmware 2.03-3.01
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

[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.
