The NXP range of drives from Vacon has recently been enhanced with the adoption of conformal coating for control boards, making the new drives better equipped to withstand the effects of prolonged operation in tough environmental conditions.
In addition to the new protective coating, the NXP control board has also been completely redesigned, with critical components upgraded to optimise temperature stability, and with a new processor that offers a 15% performance hike compared with its predecessor. This is a particular benefit for OEM customers who develop their own application software for the drives.
Other enhancements include the use of varnished cards and option boards in all power modules rated at 72A and above, and redesigned cooling channels to ensure optimal cooling and experience-based optimisation of protection limits.
For air cooled drives in the range, a new fan assembly improves drive reliability and operating life. Water cooled drives are now optionally available with an integrated brake chopper, which helps to save space.
All of the enhanced models have been evaluated using the HALT (Highly Accelerated Life Test) testing regime to ensure that the performance objectives are fully and consistently achieved in real world applications.
The drives are compatible with both induction and permanent magnet motors. Options include dynamic open- and closed-loop vector control, a range of networking and communications features, and provision for fast drive to drive communication.
