i510/i550 protec wall-mounted frequency inverter 0.37–75 kW

i510/i550 protec wall-mounted frequency inverter 0.37–75 kW

Country: Germany · Model: i510 protec / i550 protec

The i550 protec frequency inverters, 0.37–75 kW, and i510 protec, 0.37–11 kW, are mounted outside the control cabinet, on a wall, on the machine frame or next to the motor. The i550 protec housing has IP55/IP66 protection, and the i510 protec is built in IP20 per EN 60529. They are taken when there is no room in the cabinet or when the machine is divided into modules with their own drives.

Description

The electronics are the same as in the i510/i550 cabinet units of the i500 platform, with a changed housing and version. The i550 protec works from a 1×120 V mains at 0.37–1.1 kW, 1×230/240 V at 0.37–2.2 kW, 3×230/240 V at 0.37–45 kW, 3×400/480 V at 0.37–75 kW and 3×600 V at 0.75–45 kW. A maintenance switch and operating controls are connected through an expansion unit, versions with a keypad or a WLAN module are available, and there are a micro-USB diagnostic port, an IO-Link V1.1 interface, a DC bus and motor temperature monitoring. STO with SIL 3 per EN IEC 61508 and PL e per EN ISO 13849-1 is added as an option. Communication is via CANopen, EtherCAT, EtherNet/IP, Modbus RTU/TCP and PROFINET. The simpler i510 protec is supplied from 1×120/230 V, 3×230 V, 3×400/480 V and 3×600 V, communicates over CANopen and Modbus RTU and is started from the keypad, via USB or WLAN. In Europe it is not installed outside a cabinet, in the USA this is permitted (NEMA/UL Type 1).

How to choose

The protection rating decides first. For a machine in dust or splashes take the i550 protec, and for equipment under American requirements the i510 protec will also do. Above 11 kW only the i550 protec remains. The inputs and outputs are the same in both, namely 5 digital inputs, 1 digital output, 2 analogue inputs, 1 analogue output and a relay. Above +45 °C the load is derated by 2.5 %/°C. Both meet EN IEC 61800-9-2 (IE2) and have VFC eco and a PID controller.
