Frequently Asked Questions
- What EMC / RFI filter is included?
- Does it include functional safety features?
- What communications options are available?
- Which motor types are supported?
The drive supports built-in Class C3 (IEC 61800-3) EMC filtering for higher-voltage units. For 37kW, a user can opt for external filtering; lower power ranges can operate with optional filters depending on site standards.
Yes - STO (Safe Torque Off) is built-in and TÃœV-SÃœD certified as a SIL2 safety feature.
It includes native Modbus RTU (RS-485). Additional optional cards are available for Ethernet/IP, Modbus TCP, CANopen, PROFIBUS, and encoder I/O configurations.
The Unitronics B7 series supports both asynchronous induction motors and permanent-magnet synchronous motors, with SVPWM, sensorless, and closed-loop vector control modes.
