Automatically Register value changing

We are using SPINFamily Evaluation Tool 3.2 with EVLPOWERSTEP01 device for operating the stepper motor. Once we programmed the parameters the stepper motor was running with some speed e.g. 411.37 step/sec but after some time stepper motor step/sec suddenly increased automatically and at that time SPEED register was shown as 3906.5 step/sec (independent of human interference) and Status window showing Command error

I have attached a Register map and screenshot for shown SPEED is 3906.5 step/sec.

Hello @shrikant_swami 

Probably a communication error in the firmware that is then interpreted as a Run command.

Let me know if these info are useful to you.
