SINAMICS G List Manual, Edition 12.2004
Description:
Sets the controller configuration of the DC link voltage (Vdc controller) in the closed-loop control mode.
Values:
0:
Inhib Vdc ctrl
1:
Enables Vdc_max controller
2:
Enables Vdc_min controller (kinetic buffering)
3:
Enables Vdc_min controller and Vdc_max controller
Recommenda-
tion:
If fault F07403 is output, then proceed as follows:
- increase the dynamic factor (p1247).
- if this fault is still output: Increase the switch-on level (p1245).
Dependency:
Refer to: p1245
Refer to: F07403
Notice:
An excessively high value in p1245 can possibly negatively influence the normal operation of the drive.
Note:
p1240 = 1, 3:
When the DC link voltage limit, specified for the motor module 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 min-
imum DC link voltage when accelerating.
- the motor is braked in order to use its kinetic energy to buffer the DC link.
Description:
Displays the switch-in level for the Vdc_max controller.
If p1254 = 0 (automatic sensing of the switch-in level = off), then the following applies:
AC/AC drive units: r1242 = 1.15 * sqrt(2) * V_line supply = 1.15 * sqrt(2) * p0210 (supply voltage)
DC/AC drive units: r1242 = 1.15 * Vdc = 1.15 * p0210 (supply voltage)
If p1254 = 1 (automatic sensing of the switch-in level = on), then the following applies:
r1242 = Vdc_max - 50.0 V (Vdc_max: overvoltage threshold of the power module)
