Group 24: TORQUE REFERENCE CHAIN

SEL1.[TREF_A]
Input of TORQ_REF_SELECTION-function block.
Torque reference A is connected to this input.
2401 FB_I: C4
SEL1.TREF_A_FTC
Parameter of TORQ_REF_SELECTION-function block.
Filter time constant for torque reference A.
2402 FB_P: I2
SEL1.[LOAD_SHARE]
Input of TORQ_REF_SELECTION-function block.
Load share is connected to this input.
Load share is used to scale the torque reference A.
SEL1:OUT = SEL1.[LOAD_SHARE] * SEL1.TREF_A_FTC / 4000
2403 FB_I: C4
SEL1.[TREF_B]
Input of TORQ_REF_SELECTION-function block.
Torque reference B is connected to this input.
2404 FB_I: C4
SEL1.TREF_B_SLOPE
Parameter of TORQ_REF_SELECTION-function block.
The slope of the ramp for torque reference B.
Given as the time from 0 to 100 % torque.
2405 FB_P: I2
SEL2.TREF_SEL
Parameter of TORQ_REF_HANDLING-function block.
Selection for the source of torque reference:
0 = NONE
1 = SPEED_CONTROLLED
2 = EXT.TORQUE REF
3 = MIN
4 = MAX
5 = WINDOW
