4.2 Motor Status Screen

The Motor Status screen furnishes a range of information concerning the motion status on each axis. It presents details such as position, speed, motion status, and specific limits and alarms. For additional settings, click to expand the Advanced Motor Status Screen.

Notes:

Clear pulse counter values – Click the button to set value of the command pulse counter 0 for that axis. There is no other condition.
Clear error status – Click the button to clear the error status of the axis. There is no other condition.
The Status window displays text related to the value returned from the MST[axis] command, as shown in the chart below

Bit active	Description	Status display
None	Motor not in motion	Idle
0	Motor accelerating	Accelerating
1	Motor decelerating	Decelerating
2	Motor running at speed	Constant
8	Positive end of travel limit activated	+LIM ERR
9	Negative end of travel limit activated	-LIM ERR
10	Alarm input activated	ALARM ERR
16	Emergency stop initiated	EMG ERR
17	Indication the axis stopped via a slow down switch trigger	SD STOP
18	Waiting for In-position signal to finish move	Wait INP
19	Waiting for External Start signal to start move	Wait Ext Start
