Features:
- Coordinates armature and field control in SIMOREG DC-MASTER.
- Processes analog, serial and pulse-encoder signal paths.
- Uses the external A7009 EEPROM for non-volatile parameters.
The CUD1 architecture places converter calculations and signal conversion on one control board.
Ground-referenced analog channels connect measured values and command inputs to the control processor.
Hardware version L1 belongs to product states A1/A2 and is paired with software generations 1.xx and 2.xx.
The Siemens C98043-A7001-L1 6RY1703-0AA00 CUD1 Control Electronics Board may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

How measured values enter and leave CUD1
- Input 1: Terminals 4/5 feed the main setpoint or analog-select channel.
- Input 2: Terminals 6/7 provide a second ground-referenced analog channel.
- Outputs: Terminals 14 and 16 carry configurable analog values.
- Current signal: Terminal 12 delivers 5 V at rated armature current.
Two independent communication routes
- G-SST1: X300 supports the first RS232 or RS485 path.
- G-SST2: Terminals 56–60 form the second RS485 path.
- Reference: Each serial route includes its defined signal ground.
- Separation: The two interfaces occupy different physical connection points.
Where non-volatile data is retained
- Storage device: Parameter data resides in the EEPROM on A7009.
- Board link: CUD1 reaches that memory through connector X109.
- Power loss: Stored parameter and process data remain non-volatile.
- Hardware rule: L1 hardware belongs to product states A1 and A2.
Fault checks associated with CUD1
- F063: Verifies analog input and output compensation data.
- F064: A hardware watchdog checks the firing-pulse calculation cycle.
- F068: Monitors the main setpoint and analog measuring channels.
- Saturation limit: Inputs above about 11.3 V can trigger F068.
