System Architecture & Signal Flow
The 6SE7023-4TC84-1HF3 operates as the power stage within the MASTERDRIVES MC chassis. The signal flow is as follows:
- AC Mains Input (L1/L2/L3) → Rectifier Bridge → DC Bus (540–680 V DC)
- DC Bus → IGBT Inverter Stage → 3-phase PWM output to motor terminals (U/V/W)
- Control Board (CU) receives speed/torque setpoints via PROFIBUS-DP or analogue input (0–10 V / 4–20 mA)
- Encoder Feedback (optional SBP board) closes the speed/position loop for servo-class accuracy
- Fault & Status signals output via relay contacts and PROFIBUS process data words (ZSW/HIW)

Technical FAQ
Q: Is the 6SE7023-4TC84-1HF3 compatible with SIMATIC S7-300/400 via PROFIBUS?
A: Yes. With the CBP2 option board installed, the drive appears as a standard PROFIBUS-DP slave (GSD file: SI0080B6.GSD) and integrates directly with S7-300/400 or S7-1500 via DP/DP coupler.
Q: Can this board replace a 6SE7023-4TC84-1HF0 or 1HF1 variant?
A: The -1HF3 suffix denotes the firmware/hardware revision. Mechanical and electrical interfaces are identical; parameter sets (P-files) are forward-compatible. Confirm firmware version with our technical team before substitution.
Q: What is the minimum order quantity (MOQ)?
A: MOQ is 1 piece. Volume pricing available for orders of 5+ units.
Q: Do you provide a test report?
A: Yes. A unit-specific functional test report is included with every shipment at no additional charge.
Q: What is the lead time for out-of-stock units?
A: Typical lead time for sourced units is 7–15 business days. Express sourcing (3–5 days) available for urgent requirements.
