Frequently Asked Questions

Q: What makes the 25C-E1P7N104 different from the PowerFlex 525?

A: The 527 has dual embedded EtherNet/IP and integrated safety (STO). It drops the RS-485 DSI port found on the 525.

Q: Can I use this drive with a single-phase input?

A: Yes, but you get 35% of the rated output. Full rating needs three-phase input.

Q: Does the drive include an EMC filter?

A: No. External filters are needed for EN 61800-3 Category C1/C2/C3 compliance.

Q: How do I achieve 70°C ambient operation?

A: Fit the 25-FANx-70C control module fan kit. This raises the max surrounding air temperature.

Q: What is the STO response time?

A: The STO function responds in less than 12 ms, certified to SIL CL 3 / PLe.

Q: Can I add a communication card to the 527?

A: No option-card slot is published for the 527. Use the embedded EtherNet/IP ports for network communication.

Q: What brake resistor do I need?

A: The drive has an integral brake IGBT. Select an external resistor sized for your stopping duty.

Q: Does this model meet Ecodesign requirements?

A: Yes. It meets IE2 efficiency class under EU 2019/1781 and UK SI 2021 No. 745.

Q: How much installation space is required?

A: Frame A measures 152 × 72 × 172 mm. Allow clearance for fan airflow and wiring.

Q: Is Modbus RTU supported on the 527?

A: No. The PowerFlex 527 does not publish a Modbus or RS-485 DSI interface.
