4.4.22.5 Parameter description
The mode of operation of the power-off function and the associated objects of the
CDM are described in the following.

ru63
Uic voltage at Power
On
The rated DC link voltage is determined after switching
on the supply voltage in no-load operation and stored in
object ru63.
The power failure level is given as a percent value of the
rated DC link voltage. This makes it possible to parame-
terize the function independently of the mains voltage
(e.g. 400V or 480V).
The power recovery is detected if the DC link is for 50ms
higher than (ru63 - 50V).

UINT16
DC voltage trigger level
[ru63%]
Start level for power off in percentage according to ru63, de-
pending on the DC link voltage.
3
UINT16
DC voltage ref. [ru63%]
DC setpoint, percentage to ru63.
If the DC setpoint is set < start level, it is internally limited to
the start value, otherwise the DC controller will try to reduce
the voltage in the DC link by acceleration at the motor torque
limit (see SubIdx ).
4
UINT16
restart speed level [Nn%]
If the speed is above the restart level at power recovery detec-
tion, the CDM returns to "operation enable" if it has been in
this state before power off.
5
UINT16
stopping speed level
[Nn%]
Below this speed, the CDM changes from DC-Ctrl to Speed
Ctrl (target setpoint =0 rpm, ramp values from co48-59). The
standard torque limit is applied (cs group). This level must not
be below the model shutdown level, otherwise control is no
longer possible (ds group).
