A 15
Group 4: CURRENT CONTROL
[TORQ_REF]
Input of CURRENT CONTROL-function block. ( S7/16 )
401 FB_I: C4 SC: TORQ HL: 19999 LL: 0 D: 12402 U: -
[CURR_REF]
Input of CURRENT CONTROL-function block. ( S7/16 )
Either current or torque reference is used depending on value of REF_TYPE_SEL-
parameter.
402 FB_I: C4 SC:MCURR HL: 19999 LL: 0 D: 12526 U: -
[CURR_STEP]
Input of CURRENT CONTROL-function block. ( S7/16 )
Additional current/torque reference added to the main reference.
403 FB_I: C4 SC: - HL: 19999 LL: 0 D: 12527 U: -
[BLOCK]
Input of CURRENT CONTROL-function block. ( S7/16 )
A block-command for the current controller. The controller will try to decrease the
armature current to zero as fast as possible.
404 FB_I: C4 SC: BI HL: 19999 LL: 0 D: 0 U: -
REF_TYPE_SEL
Parameter of CURRENT CONTROL-function block. ( S7/16 )
Selector for the main reference:
0 = TORQ_REF
1 = CURR_REF
405 FB_P: E2 SC: - HL: 1 LL: 0 D: 0 U: -
ARM_CURR_REF_SLOPE
Parameter of CURRENT CONTROL-function block. ( S7/16 )
The maximum slope of the current reference (di/dt). Given as largest amount for
reference change during 3.3 ms (2.7 ms in 60Hz supply).
406 FB_P: I2 SC:MCURR HL: 4100 LL: 0 D: 1366 U: A
ARM_CURR_PI_KP
Parameter of CURRENT CONTROL-function block. ( S7/16 )
Proportional gain for PI-type current controller:
output = ARM_CURR_PI_KP * error / 256.
407 FB_P: I2 SC: - HL: 2977 LL: 3 D: 300 U: -
ARM_CURR_PI_KI
Parameter of CURRENT CONTROL-function block. ( S7/16 )
Integration gain for PI-type current controller:
Time constant = 16384 * 3,33 / ARM_CURR_PI_KI (50 Hz supply)
16384 * 2,77 / ARM_CURR_PI_KI (60 Hz supply).
408 FB_P: I2 SC: - HL: 31968 LL: 0 D: 3200 U: -
ARM_CONT_CURR_LIM
Parameter of CURRENT CONTROL-function block. ( S7/16 )
Current level where current changes from discontinous to continous. Value is set by
the auto-tuning or manual tuning function of the current controller.
409 FB_P: I2 SC: CCURR HL: 4100 LL: 0 D: 2050 U: A
