EURO 404 - Motion Problem at SERVO_PERIOD 250
A motion problem could occur when running MC403, MC405, Euro404 or Euro408 at 250 usec servo period. The moves would stop (buffers frozen) and an uncommanded movment could occur on one axis in an XY pair. The issue occured very infrequently and was fixed in V2.0303 firmware.
Using 2.0303 and later is recommended when running at either 125 usecs or 250 usecs SERVO_PERIOD.
This issue does not affect EtherCAT or RTEX capable Motion Coordinators, or the MC508.
