F037 Analog input Check the connection to
• Analog input 1 -X102:15, 16.
• Analog input 2 -X102: 17, 18.
Check parameters
• P632 CU AnaIn Conf
• P634 CU AnaIn Smooth
• P631 CU AnaIn Offset
F038 Voltage OFF during parameter storage
During a parameter task, a voltage failure
occurred on the board.
Re-enter the parameter. The number of the
parameter concerned can be seen in fault
value r949.
F040 AS internal
Incorrect operating status
Replace CU (-A10)
F041 EEPROM fault
A fault has occurred when storing the values
in the EEPROM.
Replace CU (-A10)
F042 Calculating time
Calculating time problems
Reduce the calculating time load:
• Increase P357 Sampling Time
• Calculate individual blocks in a slower
sampling time
Observe r829 CalcTimeHdroom.
F044 BICO Manager
F045 Opt. Board HW
A hardware fault has occurred when
accessing an optional board.
Replace CU
Check connection of the board subrack to the
boards
F046 Par. Task Power the unit down and up again.
Replace CU (-A10).
F047 Internal calculating time
The calculating time in the gating unit
computer is not sufficient.
Replace CU (-A10).
For synchronous motors (P095 = 12):
Pulse frequency is set too high
(P340 > 2kHz).
F048 Internal pulse frequency Change P340 Pulse Frequency.
F049 SW Version
The firmware versions on the CU have a
different firmware release.
Use uniform firmware
F050 TSY Init.
Error when initializing the TSY board
Check:
• Whether the TSY is correctly inserted
