Vector drives

The Synplus SPL200 and SPL400 series of sensorless vector drives complement the VVVF drives range designed to enhance process control and facilitate the ongoing introduction of mechatronic drives technology.

The drives are suitable for a range of applications, typically involving food and beverage processing, manufacturing, materials handling (including cranes and hoists), metalworking, primary product processing, air movement and water including wastewater treatment.

The SPL series features a simple 'plain text' user interface that allows commissioning, programming and system monitoring right from the in-built display without having to refer to complex parameter menus.

Simplicity of operation is complemented by high-end features, in the form of 150% over-torque capacity from as low as 1 Hz motor speed. The precisely regulated over-torque capacity permits the drive to handle high inertia initial loads without permitting excessive current draws that could both increase energy bills and potentially damage the driven machine.

The series also give precise speed regulation - as close a 0.5% per setting - delivered from the Flux Vector mode.

Features include: ratings and selection with 150% overload for 60 s (200% for 1 s) based on 8 kHz pulse width modulation for general-purpose constant torque applications; can be used with Bonfiglioli Drive Link software for programming and storing macros, as well as monitoring and set-up using drive monitor function all in a simple Windows-based GUI; in-built PLC functionality with freely configurable timers, comparators and step logic module to control process applications; modular extendibility from the freely available communication, mounting and I/O expansion modules; and matched performance figures when used in conjunction with Bonfiglioli mechanical gearmotors for maximum precision in particular applications.
