System Architecture & Signal Flow
The 6SE7031-5EF60-Z operates on a standard AC-DC-AC conversion architecture:
- Rectifier Stage: 6-pulse diode rectifier converts 3-phase AC supply to DC bus voltage
- DC Bus: Intermediate DC link with capacitor bank for energy storage and ride-through
- Braking Chopper (G93): Dissipates regenerative energy via external braking resistor during deceleration
- IGBT Inverter Stage: PWM-controlled IGBT bridge generates variable-frequency, variable-voltage output to motor
- Control Board: DSP-based vector control processor with closed-loop speed/torque regulation
- PROFIBUS-DP Interface (G41 / CBP2): Cyclic process data exchange (setpoints, actual values) and acyclic parameter access (PKW) with PLC/DCS master
- I/O Expansion (K80): Additional analog and digital I/O channels for process feedback and auxiliary control signals

Technical FAQ
Q: Is this unit compatible with Siemens SIMATIC S7-300/400 PLCs via PROFIBUS-DP?
A: Yes. The G41 option board (CBP2) supports PROFIBUS-DP V1 and is fully compatible with S7-300, S7-400, and S7-1500 PLCs using the PROFIdrive profile.
Q: Does the G93 option include the braking resistor?
A: No. G93 is the integrated braking chopper only. An external braking resistor sized to the application must be connected to the DC bus terminals. Konmask can advise on resistor sizing.
Q: Can this drive operate in sensorless vector control mode without an encoder?
A: Yes. The 6SE7031-5EF60-Z supports both sensorless (open-loop) and closed-loop vector control. Encoder feedback is required only for high-precision speed or torque applications.
Q: What is the lead time for this part number?
A: Typical lead time is 3–7 business days for in-stock units. Contact us for current availability.
Q: Can you provide a test report or inspection certificate?
A: Yes. A pre-shipment inspection report is available upon request at no additional charge.
