a module defined tag indicating servo motor not turning

We have a servo motor that moves a chute horizontally. The chute drops the parts when the chute door opens. However, sometimes the door closes too soon, clamping the part that had not quite finished falling out.

I want to add a HMI button for the operator to manually open the door to free the stuck part, but the door must not open while the chute is moving. So the manual button must be enabled only when the chute is not traveling.

Our set up uses RSLogix 5000 (v. 19.01) and Kinetix 6500 with a servo motor.

Is there any servo axis tag from the Kinetix that I can use in order to indicate a status of the motor shaft NOT turning?

Thanks.

Run a trend on the .ActualVelocity value of the Axis tag and see if it's stable enough to use in a "LES" instruction while the axis is at a standstill.

What instructions run the chute axis ?

If the axis is not being homed, or jogging, or gearing, or under the command of a motion instruction like MAM, then the .JogStatus, .GearingStatus, .HomingStatus and .MoveStatus bits will all be false.

Would the .MoveStatus be true when jogging or homing?

you are not after the .movestatus - that is turned on when a MAM Command is active

I either create my own using .AverageVelocity OR use VelocityStandstillWindow and VelocityStandstillStatus

for the MoveStatus to find out when it is turned on
