SPEED LOOP
Parameter
Tag
Range
RATIO 2 (A3) 7 -3.0000 to 3.0000
Speed Setpoint 2 Ratio.
SETPOINT 3 291 -105.00 to 105.00 %
Speed Setpoint 3 (Default Ramp O/P).
SETPOINT 4 41 -105.00 to 105.00 %
Speed Setpoint 4 (Default 5703 I/P).
MAX DEMAND
357
0.00 to 105.00 %
Sets the maximum input to the speed loop. It is clamped at 105% to allow for overshoot in the external loops.
MIN DEMAND
358
-105.00 to 105.00 %
Sets the minimum input to the speed loop.
PRESET TORQUE 595 -200.00 to 200.00 %
The PRESET TORQUE is pre-loaded into the speed loop integral store as the speed loop in enabled. This is scaled by PRESET T SCALE.
This may be used to pre-load the output of the speed loop in elevator/hoist applications to prevent the load from falling back when the brake is
released. PRESET T SCALE may be used in situations where the load may vary.
PRESET T SCALE 604 -200.00 to 200.00 %
Scaler for PRESET TORQUE.
MODE 268 See below
Selects the speed breakpoint input signal.
0 : DISABLED
1 : SPD FBK DEP Speed Feedback Dependent
2 : SPD ERR DEP Speed Error Dependent
3 : CUR DMD DEP Current Demand Dependent
SPD BRK 1 (LOW) 269 0.00 to 100.00 %
Speed breakpoint 1 to start gain profiling.
SPD BRK 2 (HIGH) 270 0.00 to 100.00 %
Speed breakpoint 2 to stop gain profiling.
