Title: Message

Hi Martin,

 

I am writing the MotorRecord driver support for Hytec Electronics Ltd. 

 

I can confirm that the Hytec driver fully supports the MOVING bit, bit 11 of the MSTA,

it is directly updated from a register bit in the hardware.

Subject: Motor Record Status Field

Hi,

 

Bit 11 of the MSTA field of the motor record is a MOVING state, which is true when the motor has a non-zero velocity. Does anybody know if this bit actually works? I'm currently using version 4.6 of the motor record to drive a stepper motor with an encoder, and this field always remains false. Having looked at the code (version 4.6 and version 4.8) it doesn't appear to get set anywhere.

 

Many thanks,
