Reduced acceptance after a component has been replaced and a
firmware change
After a component has been replaced or the firmware updated, a reduced acceptance test of
the safety functions must be performed.

Documentation
Replacing the Control Unit or the
inverter with an identical type
An acceptance test for the
safety functions is not re‐
quired.
Only check the motor's direc‐
tion of rotation.
● Supplement the inverter data
● Document the modified
checksum and time stamp

● Countersignature
Replacing a Power Module with an
identical type
Supplement the hardware version
in the inverter data.
Replacing the motor with an identi‐
cal pole pair number
No change
Replacing the gearbox with an
identical ratio
Replacing the Safe Brake Relay
Check the SBC function.
Supplement the hardware version
in the inverter data.
Replacing the safety-related pe‐
ripherals (e.g. Emergency Stop
switch).
Check the control of the safe‐
ty functions affected by the
components that have been
replaced.
No change
Inverter firmware update
An acceptance test for the
safety functions is not re‐
quired.
Check as to whether the firm‐
ware update was successful
and the inverter functions as
expected.
● Supplement firmware version
in the inverter data
● Document the modified

The inverter changes the following parameters after replacing converter components and after a
firmware update:
- checksum r9781
- time stamp r9782
