Siemens 6SW1701-0DA14V98113-A1680-A1-4.8 Replacement for SIMOVERT

Product Overview

Siemens 6SW1701-0DA14V98113-A1680-A1-4.8 Replacement for SIMOVERT: Smooth Transition & Legacy System Compatibility

When your SIMOVERT drive system reaches end-of-life or a critical control board fails, unplanned downtime can cascade across an entire production line. The Siemens 6SW1701-0DA14V98113-A1680-A1-4.8 Drive Control Module is a proven replacement and upgrade solution for facilities running legacy SIMOVERT Master Drives and SIMOVERT P series variable-frequency drive (VFD) platforms. Whether you are executing a planned retrofit or responding to an emergency breakdown, this module is engineered to restore full drive functionality with minimal re-engineering effort.

This control board targets engineers and procurement teams managing aging Siemens drive infrastructure — particularly installations where the original firmware version A1680-A1-4.8 is embedded in the drive’s operational logic. The module retains full compatibility with the SIMOVERT communication architecture, including USS protocol over RS-485 and PROFIBUS-DP interfaces commonly found in coordinated multi-drive systems. Replacing the control board does not require reprogramming the upstream Siemens S7-300 or S7-400 PLC controller, provided the drive parameters are backed up and restored via the SIMOVERT parameter set transfer procedure using a PC adapter or STARTER commissioning software.

Seamless Upgrade Solutions

A successful SIMOVERT drive modernization rarely involves a single component. In practice, field engineers replacing the 6SW1701-0DA14V98113-A1680-A1-4.8 control board often find it necessary to evaluate adjacent components to ensure system-wide reliability after the swap.

The SIMOVERT power section (e.g., 6SE7021 or 6SE7023 series inverter units) should be inspected for capacitor aging and IGBT health before commissioning the new control board — a degraded power stage will shorten the life of any replacement control module. Similarly, the 6SY7000-0AD87 IGBT module and associated gate driver boards are common wear items in high-cycle applications and are worth replacing proactively during the same maintenance window.

For facilities using PROFIBUS-DP as the primary fieldbus, the CBP2 communication board (6SE7090-0XX84-0FF5) plugs directly into the SIMOVERT option slot and enables seamless integration with Siemens S7-300 or S7-400 controllers via DP master. If your existing CBP2 board shows intermittent communication faults, replacing it alongside the control board eliminates a common source of post-retrofit instability.

Operator interface continuity is another consideration. The OP1S operator panel connects to the SIMOVERT control board via the serial interface and is used for parameter upload, download, and on-site diagnostics. Ensuring the OP1S firmware is compatible with the A1680 firmware revision prevents parameter transfer errors during commissioning. Alternatively, a PC adapter USB (6ES7972-0CB20-0XA0) connected to the drive’s RS-232 port and running STARTER software provides a more flexible commissioning path for engineers already familiar with the Siemens toolchain.

In multi-drive cabinet installations, the 24 VDC SITOP power supply (e.g., 6EP1334-2BA20) feeding the control electronics should be load-tested before the retrofit. An undersized or aging SITOP unit is a frequent root cause of unexplained control board resets after replacement. Pairing the new control board with a verified SITOP supply eliminates this variable from post-commissioning troubleshooting.

For applications where the SIMOVERT drive interfaces with a legacy Siemens S5-115U or S5-135U PLC via hardwired I/O rather than fieldbus, verifying the 24 VDC digital input signal levels and ensuring the terminal block wiring (X101, X102) matches the new board’s I/O map is essential. In most cases, the terminal assignments are preserved across control board revisions, but a wiring audit against the drive’s circuit diagram is always recommended before energizing. Where signal isolation is required between the drive and upstream control system, a signal isolator or relay terminal module (such as those from the Siemens SIRIUS 3RS series) can be inserted at the I/O interface without affecting the control board replacement procedure.

Retrofit Guidance FAQ

Q: Do I need to rewire the drive after replacing the control board?
No. The 6SW1701-0DA14V98113-A1680-A1-4.8 uses the same terminal block layout as earlier SIMOVERT control board revisions. All existing wiring to X101, X102, and the fieldbus connector remains in place.

Q: Will my existing PROFIBUS-DP configuration still work?
Yes. The module supports PROFIBUS-DP via the CBP2 option board. The DP node address and GSD file configuration on the PLC side do not need to change, provided the CBP2 board is retained or replaced with an equivalent unit.

Q: Do I need to re-enter all drive parameters after the swap?
You should back up parameters before the swap using an OP1S operator panel or STARTER software. After installing the new board, restore the parameter set. The A1680-A1-4.8 firmware is factory-loaded; no firmware flashing is required on-site.

Q: Is this module compatible with both vector control and V/f control modes?
Yes. The SIMOVERT Master Drives platform supports both closed-loop vector control (with encoder feedback via the SBP pulse encoder board) and open-loop V/f control. The replacement board supports all control modes available in the A1680 firmware revision.

Q: How much physical space does the installation require?
The control board is a direct PCB replacement within the existing SIMOVERT drive chassis. No additional cabinet space or DIN rail mounting is required. The board slides into the existing guide rails and connects via the internal ribbon cable and option board connectors.

Q: What if my system uses USS protocol instead of PROFIBUS?
USS protocol over RS-485 is natively supported on the control board’s serial interface. No additional hardware is required. Baud rate and USS address settings are restored from the parameter backup.

Q: Can this board be used in a SIMOVERT VC (Vector Control) chassis?
Yes, provided the chassis frame size and power rating match the 6SW1701-0DA14 control board specification. Always cross-reference the drive’s type plate and order number against the board’s compatibility matrix before ordering.
