FAQ

Yes, while the integrated keypad is sufficient for basic setup, the Altivar 18 series can also be programmed using an optional remote keypad (VW3A18201) or via a PC with PowerSuite software, connected through the Modbus port.

The ATV18U18N4 has built-in DC injection braking capabilities. However, it does not have a built-in dynamic braking chopper. For applications requiring rapid deceleration or handling overhauling loads, an external braking resistor and a separate braking unit would be necessary.

No, the Altivar 18 series is an older generation drive. Its primary communication protocol is Modbus RTU via its serial port. It is not natively compatible with modern Ethernet-based protocols like EtherNet/IP or Profinet. A gateway would be required for integration into such networks.
