2 Parameters
2.2 List of parameters
Description:
Status word of the DC braking.
Dependency:
Refer to: p1231, p1232, p1233, p1234
Note:
For bit 12, 13:
Only effective for p1231 = 14.
Description:
Sets the controller configuration of the DC link voltage (Vdc controller) in the closed-loop control mode.
For U/f control: see p1280.
Value:
0:
Inhibit Vdc ctrl
1:
Enable Vdc_max controller
2:
Enable Vdc_min controller (kinetic buffering)
3:
Enable Vdc_min controller and Vdc_max controller
Dependency:
Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
Refer to: p1245
Refer to: A07400, A07401, A07402, F07405, F07406
Notice:
An excessively high value in p1245 can possibly negatively influence the normal operation of the drive.
Note:
If a braking resistor is connected to the DC link (p0219 > 0), then the Vdc_max control is automatically deactivated.
p1240 = 1, 3:
When the DC link voltage limit specified for the power unit is reached the following applies:
- the Vdc_max controller limits the regenerative energy in order that the DC link voltage is kept below the maximum
DC link voltage when braking.
- the ramp-down times are automatically increased.
p1240 = 2, 3:
When the switch-in threshold of the Vdc_min controller is reached (p1245), the following applies:
- the Vdc_min controller limits the energy taken from the DC link in order to keep the DC link voltage above the
minimum DC link voltage when accelerating.
- the motor is braked in order to use its kinetic energy to buffer the DC link.
