PARAMETER DESCRIPTIONS
111
fPRM:58 – Slow Zone Part Unloaded Position2
Variable Units: Inches
Description: This parameter sets the height that the hoist will start to run at a reduced speed when a part is
not loaded and the hoist is moving up.
This parameter is only processed if the Slow Zone is turned on. i.e. [iPRM:0 ‘Slow Zone Mode’ is non-zero].
KSS Workspace tree location: Knight WO# \ Hoist Configuration \ Slow Zone \ Row 3.
fPRM:59 – Slow Zone Max Decel
Variable Units: Inches per second
2
Description: This parameter sets the deceleration constant when the hoist approaches the slow zone and
transitions from the normal speed to the reduced speed.
This parameter is only processed if the Slow Zone is turned on. i.e. [iPRM:0 ‘Slow Zone Mode’ is non-zero].
KSS Workspace tree location: Knight WO# \ Hoist Configuration \ Slow Zone \ Row 2.
fPRM:60 – Spare
fPRM:61 – Impulse Limiting Speed
Variable Units: Inches per second
Description: This parameter sets the speed that the hoist will slow to when impulse limiting is enabled and a
sudden increase in weight is detected.
KSS Workspace tree location (User Level = Advanced): Knight WO# \ Tuning \ Impulse Limiting \ Row 1.
fPRM:62 – Impulse Limiting Max Speed
Variable Units: Seconds
Description: This parameter limits the command reference while impulse limiting is active to create a better
transition when coming out of impulse limiting and returning to normal operation.
KSS Workspace tree location (User Level = Advanced): Knight WO# \ Tuning \ Impulse Limiting \ Row 2.
fPRM:63 – Impulse Limiting Scale Factor
Variable Units: Real Number
Description: Multiplier for impulse filter weight used when determining impulse limiting threshold weight.
KSS Workspace tree location (User Level = Advanced): Knight WO# \ Tuning \ Impulse Limiting \ Row 3.
fPRM:64 – Impulse Limiting Offset
Variable Units: Pounds
Description: Impulse offset in pounds used to determine minimum impulse threshold weight.
KSS Workspace tree location (User Level = Advanced): Knight WO# \ Tuning \ Impulse Limiting \ Row 4.
fPRM:65 – Impulse Limiting Filter Constant
Variable Units: Real Number
Description: Filter Constant for Impulse Detection.
KSS Workspace tree location (User Level = Advanced): Knight WO# \ Tuning \ Impulse Limiting \ Row 5.
fPRM:66 – Spare
fPRM:67 – Calibration Weight
Variable Units: Pounds
Description: This parameter sets the weight that is hung from the shackle in order to calibrate the float load
cell’s gain when pressing the ‘SET GAIN’ button on Float Load Cell screen. This weight should be greater
than one half the hoist capacity as a minimum, up to the maximum capacity of the hoist.
KSS Workspace tree location: Knight WO# \ Hoist Configuration \ Float Load Cell \ Row 2.
fPRM:68 – Lift LC Gain
Variable Units: Pounds / Volt
Description: This parameter is typically static and should not be changed. It shows the gain value of the
750lb lift load cell located inside the inline handle. The nominal value is 26 lb/v.
