The C98043-A7005-L1 6RY1704-0AA00 is the standard Parameterization Unit (PMU) operator panel board dedicated to Siemens SIMOREG DC-MASTER 6RA70 series DC drives. Mounted directly in the center of the drive's front cover, it integrates a 5-digit red LED display and 4 tactile pushbuttons.
No external power required; ribbon cable links directly to the internal CUD1 board for power and total data access
Connects to a PC via X300 for DriveMonitor/STARTER trace recording and data archiving
Solid-state circuits in an anti-static bracket, ensuring high accuracy in intense electromagnetic and thermal environments
Powered directly via a ribbon cable from the internal CUD1 main control board without requiring an external supply, the board is utilized for on-site drive parameterization, real-time running status monitoring, and reading system alarm or fault diagnostic codes. Additionally, its onboard X300 port supports the USS communication protocol, allowing direct insertion of an advanced OP1S LCD handheld panel or connection to a PC running DriveMonitor software.
Electrically, this control board requires no independent external power supply input. Its necessary low-voltage operating current is drawn entirely via an integrated multi-conductor flat ribbon cable connected straight to the drive's internal CUD1 main control board. Beyond basic code readouts and button inputs, the board also incorporates a standard X300 port on its lower-left corner. This interface supports serial RS232 and RS485 connections utilizing the USS communication protocol, which allows technicians to plug in an advanced OP1S LCD handheld operator panel or establish a cable link to a PC running the DriveMonitor software.
Utilizing solid-state integrated circuits and sealed micro-switches, this board is fully capable of withstanding the intense electromagnetic and thermal interference present inside high-voltage, heavy-current three-phase fully controlled rectifying DC drive converters, completing parameter routing, diagnostic code capturing, and real-time status feedback without latency.

Metallurgy & Iron and Steel Industry
Used for the speed and torque control of high-power DC motors in blast furnace hoists, main rolling mills (roughing/finishing), and continuous casting machines.
Paper and Printing Industry
Used for high-precision tension and synchronized speed control in the main drives and winders of large multi-section paper machine production lines.
Cement and Building Materials Industry
Used in the main drive systems of large rotary kilns in cement plants, providing high torque output during low-speed start and smooth deceleration.
Oil and Gas Drilling Industry
Used for the DC drives of critical drilling equipment including oil rig mud pumps, drawworks, and rotary tables.
Rubber and Plastics
Used for the DC main motors of large internal mixers, twin-screw extruders, and rubber calenders to handle high overload shocks.
Metal Machine Tool Machining Industry
Used for the DC speed regulation retrofit and upgrading of spindles and feed systems in legacy large gantry planers and gantry milling machines.
When servicing this control board, hot-plugging the rear flat ribbon cable is strictly prohibited; all main and control power supplies to the drive must be completely isolated before handling to prevent transient high-voltage currents from damaging sensitive solid-state integrated circuits. During daily operation, ensure the drive's front protective cover remains intact, and never allow conductive metal dust, moisture, or oil grease to infiltrate the panel gaps.
Furthermore, field technicians must execute strict electrostatic discharge (ESD) mitigation protocols (such as wearing an anti-static wrist strap) before touching or replacing the board to avoid static breakdown of onboard electronic components.
This control board assembly is the standard on-site human-machine interface core hardware component utilized across the Siemens SIMOREG DC-MASTER 6RA70 series DC drives. The component is physically identified by two distinct codes: C98043-A7005-L1 denotes the internal Siemens printed circuit board manufacturing code, while 6RY1704-0AA00 serves as the official commercial ordering number for global logistics and spare parts procurement. Embedded directly into the center of the drive’s front cover, the board operates as the Parameterization Unit (PMU). Its surface integrates a 5-digit, seven-segment high-brightness LED display alongside several tactile buttons for parameter addressing, value adjustment, fault resetting, and local inching toggles, providing field technicians with a direct window to oversee the drive’s condition without external devices.
It is the standard PMU Operator Panel and interface board for Siemens SIMOREG 6RA70 series DC drives.
What is the difference between C98043-A7005-L1 and 6RY1704-0AA00?
C98043-A7005-L1 is the internal Siemens PCB manufacturing number, whereas 6RY1704-0AA00 is the corresponding official commercial ordering number (MLFB number).
How to use products like C98043-A7005-L1 6RY1704-0AA00?
Snap it directly into the front housing of the 6RA70 DC drive, and connect it to the internal main control board (CUD1 board) via the ribbon cable connector on its back.
Can C98043-A7005-L1 6RY1704-0AA00 connect to external commissioning devices?
Yes, the onboard integrated X300 connector (supporting USS protocol via RS232/RS485) can be used to plug in an advanced OP1S handheld panel or connect a PC running DriveMonitor software via an extension cable.
Can C98043-A7005-L1 6RY1704-0AA00 be plugged or unplugged while the drive is energized?
Hot-plugging is strictly prohibited. To prevent transient current from destroying sensitive solid-state integrated electronics, all main and control power supplies to the drive system must be isolated before handling.
