Why Engineers Specify This Model
- PROFIBUS-DP Integration (-1HF3): The -1HF3 option board provides native PROFIBUS-DP connectivity, enabling seamless integration into SIMATIC S7 PLC networks and distributed I/O architectures without additional gateways.
- True Vector Control: Closed-loop and sensorless vector control delivers precise torque regulation from near-zero speed — critical for hoists, winders, and process lines where speed accuracy is non-negotiable.
- Proven MASTERDRIVES Platform: Backed by decades of field deployment in heavy industry, the SIMOVERT MASTERDRIVES platform offers extensive spare-parts availability, global service networks, and well-documented parameter sets.
- High Overload Tolerance: 150%/60 s overload rating handles demanding start cycles in compressors and conveyors without nuisance tripping.
- Modular Option Board Architecture: Supports encoder feedback, additional I/O, and technology boards (T400, T100) for application-specific control functions.
- Energy Efficiency: Variable-speed operation on pump and fan loads typically reduces energy consumption by 30–50% versus fixed-speed DOL starters.

Application-Specific FAQ
Q: Can the 6SE7027-2TD84-1HF3 control a pump in a closed-loop pressure control loop?
A: Yes. With a PROFIBUS-DP connection to a SIMATIC S7 PLC and a 4–20 mA pressure transmitter wired to the drive’s analog input, closed-loop PID pressure control is fully supported via the drive’s built-in technology functions.
Q: Is this drive compatible with SIMATIC S7-300/400 via PROFIBUS?
A: Yes. The -1HF3 option board provides a native PROFIBUS-DP slave interface. The drive is fully compatible with SIMATIC S7-300, S7-400, and S7-1500 (via DP master) using standard GSD files.
Q: What motor types are supported?
A: Standard asynchronous (induction) motors and synchronous motors (with encoder feedback). The drive supports both sensorless vector and closed-loop vector control modes.
Q: Can I use this drive as a replacement for an existing 6SE70 series unit?
A: In most cases, yes — provided the power rating, voltage class, and option boards match. Parameter sets from existing units can be uploaded via the serial interface or PROFIBUS for rapid commissioning.
Q: What is the difference between the -1HF3 and other option suffixes?
A: The -1HF3 suffix denotes the PROFIBUS-DP communication option board. Other suffixes indicate different fieldbus options (e.g., DeviceNet, CANopen) or technology boards. Confirm your fieldbus protocol before ordering.
