2 Parameters
2.2 List of parameters
p3422

DC link capacitance total / C_DC tot

VECTOR_G Can be changed: U, T
(Tech_ctrl)
Data type: FloatingPoint32
P-Group: Closed-loop control
Not for motor type: -
Min
0.20 [mF]
Description: Sets the total DC link capacitance for closed-loop voltage control.
The capacitance of one power unit is pre-assigned to this value. The value should be adapted according to the
number of power units.
Note: The controller setting for the DC-link voltage controller is derived from this value.
p3490

Infeed delay time OFF1 command / INF t_del OFF1

B_INF Can be changed: T
Data type: FloatingPoint32
P-Group: Closed-loop control
Not for motor type: -
Min
0.0 [ms]
Description: Sets the delay time for the ON/OFF1 command of the infeed.
After ON/OFF1 = 0 the infeed remains in operation for the specified time
Dependency: Refer to: p0840
Notice: The ON/OFF1 command of the infeed can be interrupted.
Note: This parameter is only relevant if a Motor Module and the infeed are controlled by the same OFF command. In this
case, the delay time and the stop ramp time of the motor can be coordinated with one another.
p3510

DC link voltage setpoint / Vdc setp

VECTOR_G Can be changed: U, T
(Tech_ctrl)
Data type: FloatingPoint32
P-Group: Closed-loop control
Not for motor type: -
Min
100.00 [V]
Description: Sets the setpoint for the DC-link voltage on the motor side.
p3511

CI: DC link voltage supplementary setpoint / Vdc Z_set

VECTOR_G Can be changed: T
(Tech_ctrl)
Data type: Unsigned32 / FloatingPoint32
P-Group: Closed-loop control
Not for motor type: -
Min
-
Description: Sets the signal source for the supplementary setpoint for the DC-link voltage on the motor side.
Dependency: Refer to: p3510
