Additional information appears on the screen once a particular 

motor channel is selected, including: 

Maximum travel 

Velocity 

Acceleration 

These are default values read from the firmware. The maximum travel is factory set 
according to the stage being driven, but the velocity and acceleration can be changed 
via the controller front panel at any time: see Section 4.4. 
 

4.4  Setting Motor Velocity and Acceleration 

Individual motor speed and acceleration can be set  by first selecting the appropriate 
channel (which produces a screen similar to Fig. 4.3b) then scrolling to the next page 
by pressing the lowest control panel button adjacent to "Next". This brings up a screen 
similar to Fig. 4.4a, where Step Size, Velocity and Acceleration can all be changed. 
Step Size relates to stage movement when the knob control is operating in jog mode 
- see Section 4.5. for further details. However, in all cases, the method of changing 
the parameters is the same: select what needs to be altered (e.g. Velocity in Fig. 4.4b), 
then use "+/-" buttons to increment/decrement the number indicated by the cursor. The 
cursor  position  is  changed  by  the  Resolution  button  at  the  bottom. When  finished, 
press Enter (top button). 

 

 

 

 

Fig. 4.4  Changing Motor Parameters 

 

Note: This page times out after 20 second of inactivity. 

 

During the homing process when the stage is in motion, a red "STOP" sign is 
illuminated on the display (Fig. 4.3a) and pressing the corresponding panel button 
will immediately stop the stage's motion; for example, this might be needed in case 

motors/axes, each axis must be selected 

and stopped separately. 

Important:

  The  stage  stops  traveling  when  the  “STOP”  button  is  released,  not 

when it is depressed.
