Speed Loop Pgain
0515
Parameters::Motor Control::Spd Loop
Settings
20.00
0.00 to 3000.00
ALWAYS
Sets the proportional gain of the loop.
Speed error x proportional gain = torque percent.
Speed Loop I Time
0516
Parameters::Motor Control::Spd Loop
Settings
0.100
0.001 to 1.500
s
ALWAYS
This is the integral time constant of the speed loop. A speed error which causes the proportional term to produce a torque demand T,
will cause the integral term to also ramp up to a torque demand T after a time equal to Speed Loop I Time.
Speed Loop Int Defeat
0517
Parameters::Motor Control::Spd Loop
Settings
FALSE
ALWAYS
When TRUE, the integral term does not operate.
Speed Loop Int Preset
0518
Parameters::Motor Control::Spd Loop
Settings
0
-500 to 500
ALWAYS
The integral term will be preset to this value when the drive starts.
Spd Loop Dmd Filt TC
0519
Parameters::Motor Control::Spd Loop
Settings
0.0
0.0 to 15.0
ms
ALWAYS
The speed demand is filtered to reduce ripple. The filter is first order with time constant equal to the value of this parameter.
Spd Loop Fbk Filt TC
0520
Parameters::Motor Control::Spd Loop
Settings
1.0
0.0 to 15.0
ms
ALWAYS
The speed feedback is filtered to reduce ripple. The filter is first order with time constant equal to the value of this parameter.
