5.4.11 – ‘Parameters’ Menu (continued)
Start Ped
Range: 10 to 60 percent
Default: 20%
Scaling: 1
Type: R/W
‘Start Pedestal’ sets the percentage of the unit’s rated supply voltage that is applied to the load
before the ramp starts.
(P-79 ‘Start Ped 2’ is the 2nd parameter set counterpart of P-11 ‘Start Ped’.)
Start Time
Range: 1 to 255 seconds
Default: 5s
Scaling: 1
Type: R/W
‘Soft Start Time’ sets the soft-start time period over which the unit ramps voltage to the motor.
• Start times are normally in the 5–30s range.
• Long ramp times over 1minute are for special applications only.
• The start (without current limit) is purely a voltage ramp.
• Lightly loaded motors will normally reach full speed before the end of a long ramp.
(P-80 ‘Soft Start Time 2’ is the 2nd parameter set counterpart of P-12 ‘Soft Start Time’.)
Kick Ped
Range: 60 to 90 percent
Default: 75%
Scaling: 1
Type: R/W
‘Kick Pedestal’ provides a short kick of voltage at start of ramp to dislodge sticky load.
(P-81 ‘Kick Pedestal 2’ is the 2nd parameter set counterpart of P-13 ‘Kick Pedestal’.)
Kick Time
Range: 10 to 40 cycles
Default: 25 cycles
Scaling: 1
Type: R/W
‘Kick Time’ sets the number of cycles for which Kick Ped (P13) is applied, if selected (P51/B0).
Dwell Time
Range: 1 to 255 seconds
Default: 5s
Scaling: 1
Type: R/W
‘Dwell Time’ provides a period of time following soft-start allowing the load to settle, and to
ensure that it is up to speed, before optimizing commences (if selected).
Stop Ped
Range: 10 to 60 percent
Default: 10%
Scaling: 1
Type: R/W
‘Soft Stop Pedestal’ sets the percentage of supply voltage at which the Soft Stop will cease.
The actual value is affected by certain load variations.
Stop Time
Range: 0 to 255 seconds
Default: 0s
Scaling: 1
Type: R/W
‘Soft Stop Time’ sets the time period over which the Soft Stop Ramp is performed.
