Geckodrive Brush DC drives

Gecko G320x

The G320X is the newest servo drive from Geckodrive, Inc. Built around the same high speed CPLD as the G203V and offering the same bulletproof protection, the G320X is a drive that will last. It was designed as a drop-in replacement for the G320 and is 100% backwards compatible with the G320 and G340. The G320X has many new features based on user requests and industrial requirements that take full advantage of the CPLD architecture.

?Built in step pulse multiplier
?Stall torque time limit
?Four settable following error limits
?Encoder fail detect
?Short circuit protection
?Dynamic motor braking during fault condition
