i550 motec decentralised frequency inverter IP66 0.37–45 kW

Country: Germany · Model: i550 motec

The i550 motec decentralised frequency inverter, 0.37–22 kW at 3×230/240 V and 0.37–45 kW at 3×400/480 V, is mounted directly on the motor or on a wall. The IP66 housing (UL Type 4X for indoor use) makes a control cabinet unnecessary. The parameters and setup logic match the i500 cabinet inverters, so a project can be carried over between versions.

Description

The drive is installed on the machine, so the motor cable becomes shorter and the machine is easily divided into independent modules, and connection is by standard plug connectors. For wall mounting there is an expansion unit with a disconnector, with or without a Type E combined starter, and with operating controls. The inputs and outputs are configurable in three versions. Standard-I/O has 4 DI or 3 DI and 1 DO, Application-I/O has 4 IO-Link ports and 8 DI or 4 DI and 4 DO, and Extended-I/O has 2 AI, 1 AO and 4 DI, two of which can be reconfigured as outputs. The four IO-Link ports work as a simplified IO-Link master for sensors and actuators. There are holding brake control, motor temperature monitoring and a USB-C port. Communication is via EtherCAT, EtherNet/IP, IO-Link, Modbus RTU, Modbus TCP, PROFINET and optionally CANopen. The built-in regeneration module returns braking energy, so a braking resistor is not needed. The operating temperature is −30 to +60 °C with derating of 2.5 %/°C above +40 °C, vibration resistance up to 1 g. The drive meets EN IEC 61800-9-2 (IE2) and carries CE, UKCA, cULus and RoHS marks.

How to choose

The choice depends on the set of inputs and outputs and on the mains. Standard-I/O suits simple tasks, Application-I/O adds four IO-Link ports, and Extended-I/O adds analogue inputs and an output. Power is taken by mains, up to 22 kW at 3×230/240 V and up to 45 kW at 3×400/480 V. STO is available as an option. The inverter is supplied separately and assembled with MF, m500, m550-U, m650-U and m550-V motors and with g500 geared motors.
