Frequently Asked Questions (FAQ)

• Q: What power sources work with the EP202-B00-EN00?
  A: This drive accepts 20-264 Vac single phase or 10-340 Vdc. UL approval for DC input is pending.
• Q: Which communication protocols does the EP202-B00-EN00 support?
  A: It supports RS-485 Modbus, EtherNet/IP, Modbus TCP/IP, and DeviceNet (depending on model variant).
• Q: What is the maximum pulse input frequency?
  A: Differential RS422 inputs accept 1 MHz per channel. Single ended TTL inputs accept 500 kHz per channel.
• Q: How do I connect a motor temperature sensor?
  A: Use a PTC thermistor with 2k ohm resistance at trip point. The drive trips at 0.83V and resets at 0.41V.
