ARM_L
Parameter of CURRENT CONTROL-function block.
Relative inductance of armature circuit. Value is set by the auto-tuning or manual tuning
function of the current controller.
ARM_L = L A [mH] * I_CONV_A * 245 / (U_SUPPLY * 3,33) (50 Hz supply)
L A [mH] * I_CONV_A * 245 / (U_SUPPLY * 2,77) (60 Hz supply).

ARM_R
Parameter of CURRENT CONTROL-function block.
Relative resistance of armature circuit. Value is set by the auto-tuning or manual tuning
function of the current controller.
ARM_R = 22444 * R A [ohm] * I_CONV_A / U_SUPPLY.
411 FB_P: I2 SC: -
ARM_ALPHA_LIM_MAX
Parameter of CURRENT CONTROL-function block.
Max. firing angle in degrees.
412 FB_P: I2 SC: 1
ARM_ALPHA_LIM_MIN
Parameter of CURRENT CONTROL-function block.
Min. firing angle in degrees.
413 FB_P: I2 SC: 1
DXN
Parameter of CURRENT CONTROL-function block.
Additional commutation reserve proportional to the armature current.
414 FB_P: I2 SC: 0.1
[ARM_CURR_LIM_P]
Input of CURRENT CONTROL-function block.
Positive limitation of current control block.
415 FB_I: C4 SC:MCURR
[ARM_CURR_LIM_N]
Input of CURRENT CONTROL-function block.
Negative limitation of current control block.
416 FB_I: C4 SC:MCURR
ARM_CURR_CLAMP
Parameter of CURRENT CONTROL-function block.
If |ARM_CURR_ACT| < ARM_CURR_CLAMP then ARM_CURR_ACT (10502) = 0.
417 FB_P: I2 SC: CCURR HL: 40
CURRENT_RISE_MAX
Parameter of the CURRENT CONTROL-function block.
Determines the amount of current the actual current of one after another current bubble
may differ. This setting is used to calculate the current rise monitoring function.
418 FB_P: I2 SC:MCURR
ZERO_CUR_DETECT
Parameter of the CURRENT CONTROL-function block.
Selector to enable the use of the zero current detection based on the option board SDCS-
CZD-1. This board uses the thyristor blocking voltage.
0 = DISABLED (internal zero current detection on SDCS-CON-x in use)
1 = ENABLED (option board SDCS-CZD-1 is used)
