SEW Eurodrive has released the Movidrive B series of application inverters. It combines versatility, processing power and cost-efficiency.

Seven sizes are available, with power capacities ranging from 0.55kW to 132kW. They are suited to applications ranging from standard variable speed drives up to sophisticated positioning and synchronous applications.

The inverters are among the most compact on the market. The 0 Movidrive B (0.55kW to 1.5kW) is only 45mm wide. The entire series, when installed in multiples, requires zero clearance space either side of the drive. This ensures compact bundles and minimised cabinet space usage.

The new inverter incorporates a multi-mode controller card that supports a broad spectrum of industrial applications. These range from the very basic control of an asynchronous motor in V/F operating mode to precision control of permanent magnet servo motors in CFC flux vector operating mode.

Movidrive B also supports RS-485 and CANopen serial communications as standard, plus its own system bus, which permits peer-to-peer connection of up to 31 Movidrives. Optional communications cards provide connectivity to the most common industrial fieldbus standards, including Profibus DPV1, Interbus, Interbus LWL and DeviceNet. As with version A, the new Movidrive is fully supported by a library of pre-configured software modules. These allow quick configuration of table incremental and absolute positioning tasks, winding, synchronous operation, and electronic camming.

The Movidrive B has an integrated safety stop feature. This allows a reduction of the interpose contactors required to achieve safe protection against restart in AS4024.

Upgrading and maintaining Movidrive B is easy, with a modular plug out/plug in memory card. In the event of a drive upgrade or changeout, the configured memory module is simply changed across to the new drive system. No further engineering input is required. User friendliness is enhanced by the inverter's DBG60B numeric keypad, with backlit matrix display. The keypad supports nine languages.

The Movidrive B boasts four times the code capacity of its predecessor and up to ten times the code processing speed. This is complemented by additional onboard digital I/O as standard, plus a choice of programming methods including assembler code, C-complier or the pre-developed application modules. The result is enhanced drive control and optimal drive configuration flexibility.
