Outer Control Loop Lead/Lag Low Frequency; Outer Control Loop Lead/Lag Ratio; Outer Control Loop Reference Gain - Reliance electric GV3000/SE Instruction Manual

U.042

Outer Control Loop Lead/Lag Low Frequency

Parameter Range: 0.01 to 34.90 radians/second
Default Setting: 1.0
Refer to: U.040 OCL Feedback Source
U.043 OCL Lead/Lag Ratio
U.045 OCL Proportional Gain
U.047 OCL Trim Range Percentage
Parameter Type: Tunable (at rest or during operation)
Description: This parameter specifies the lead/lag low break frequency of the outer control loop
feedback.
This parameter sets the lead break frequency if U.041(Outer Control Loop Lead/Lag
Select) = 1 (lead/lag) or the lag break frequency if U.041 = 2 (lag/lead). The upper
limit may be restricted by the lead/lag ratio setting (U.043).
See Figure 6-1c for the outer control loop block diagram.
U.043

Outer Control Loop Lead/Lag Ratio

Parameter Range: 2 to 20
Default Setting: 10
Refer to: U.040 OCL Feedback Source
U.042 OCL Lead/Lag Low Frequency
U.045 OCL Proportional Gain
U.047 OCL Trim Range Percentage
Parameter Type: Tunable (at rest or during operation)
Description: This parameter specifies the ratio between the lead/lag low break frequency and
high break frequency of the outer control loop feedback lead/lag block.
The high break frequency is determined by the values in parameters U.042 (Outer
Control Loop Lead/Lag Low Frequency) and U.043 as shown:
High break frequency = Low frequency x ratio = U.042 x U.043
See Figure 6-1c for the outer control loop block diagram.
U.044

Outer Control Loop Reference Gain

Parameter Range: -5.000 to +5.000
Default Setting: 1.000
Refer to: U.040 OCL Feedback Source
U.042 OCL Lead/Lag Low Frequency
U.045 OCL Proportional Gain
U.047 OCL Trim Range Percentage
Parameter Type: Tunable (at rest or during operation)
Description: This parameter specifies the gain to be applied to the reference entering the outer
control loop.
See Figure 6-1c for the outer control loop block diagram.
