Cable-Check: If a wiring error of the motor phases is detected, bit 3 "CableCheck failed" in the status word (0x2C64:2) is erroneously not set (corrected from V01.05.02)

Corrected from:
i950 Servo inverter FW:  from  V01.05.02.1788
 
Response of the new version:
Cable check: Status bit 3 "CableCheck failed" is now always set correctly, e.g. if one of the motor phases is not connected.

 
What happens?
Cable-Check: If a wiring error of the motor phases is detected, bit 3 "CableCheck failed" in the status word (0x2C64:2) is erroneously not set.

Background:
The wiring check (cable check) consists essentially of 2 individual tests. The first test checks whether all motor phases are connected and can carry current. Then it is checked whether the encoder position can follow a specific motor movement. If the result of all tests is positive, the cable check is considered to be successfully completed.
If, for example, one of the motor phases is not connected and the first test is negative, the second part of the check is not started and the process is terminated. In this case the status bit 3, "CableCheck failed" is erroneously set incorrectly. 

When does the behaviour occur?
If a motor phase is not connected and the device command "CableCheck" is executed.

Which products are affected?
