Operation
9.2 Parameterizing using the BOP20 (Basic Operator Panel 20)
Note
During a data save operation initiated by the user, the electronic power supply for the
SINAMICS DC MASTER must not be interrupted.
An active saving process is indicated by the following actions:
• The RDY LED flashes (see the "Description of functions" chapter, "Description of the
LEDs on the CUD" section)
• The BOP20 flashes
Interrupting the electronic power supply while saving can lead to the loss of the actual device
parameter assignment. Also refer to Chapter "Operation", Section "Memory card functions".
For certain user actions (e.g. restore factory setting) a two-digit number is displayed on the
BOP20. This number provides information about the drive state. The significance of these
numbers is provided in Appendix B.

Power up the drives for which the "ON/OFF1" command should come from the BOP.
Binector output r0019.0 is set using this key.
Power down the drives for which the "ON/OFF1", "OFF2", or "OFF3" commands should come
from the BOP.
Binector outputs r0019.0, .1 and .2 are simultaneously reset when this key is pressed. After the
key has been released, binector outputs r0019.1 and .2 are again set to a "1" signal.
Note:
Whether these keys are active can be defined by assigning appropriate BICO parameters
(e.g. it is possible to use these keys to control all of the existing drives at the same time).
The meaning of these keys depends on the current display.
Note:
The effectiveness of this key to acknowledge faults can be defined via BICO parameterization.
If this key is pressed for 3 s, the "Copy RAM to ROM" function is executed. The "S" displayed on
the BOP disappears.
The keys depend on the current display and are used to either increase or decrease values.
