Parker Hannifin mx80l precision grade 사용자 설명서

 

30 

Total mass = 0.46 kg (Payload mass = 250 grams + Carriage mass = 213 grams) 
Application Speed = 500mm/sec

 

Available peak force at .25 m/sec = 11.8 N (See Chapter 2, Force / Speed Curve) 
Maximum Obtainable Deceleration Rate

 

Thus:  F = ma Æ a = F/m Æ a = 11.8N / 0.46kg Æ   25.6 m/sec

 
Now, calculate the Deceleration Distance for linear deceleration: 
First…

 find the Deceleration time: 

 

Ta =  Max Velocity / Deceleration Rate  
Ta = .50 m/sec / 25.6 m/sec

2

  Æ  0.020 seconds 

find the Deceleration Distance: 

 

 

Distance = ((Max Velocity) * (Ta)) / 2 

 

 

Distance = ((500 mm/sec) * (0.020)) / 2  Æ  5.0 mm

 

 

 
This means that both the positive and negative limit switch targets must be moved inward by 5.0 mm.  
The limit deceleration rate should be set to 25.6 meters/sec

.  Using the supplied limit flag sheet cut two 

5.0mm long strips from the appropriate white or black (depending on configuration) marked Limit/Home 
Adjustment overlay decal and follow the procedure for changing the limits. 
 

 

The following procedure is to be used for changing the limit flag (switching activation from N.O. to N.C. or 
vice versa) and adjusting the activation position of the end of travel limits on the MX80:  (Images shown 
are for changing H3L2 to H2L3 
 

  Remove power from the unit and allow time for stage 

base and carriage to reach room temperature 
 
Step 2:

  Remove the limit flag bracket from the MX80L by 

removing the button head cap screws (BHCS) that secure the 
bracket to the side of the carriage. 
 
 

  Gently slide the bracket from out from under the carriage. 

  
 
 
 
 
 

: To adjust limits to increase travel: With a razor, cut and remove 

 

the desired amount of protective sticker and magnet which equals the 

 

amount of desired travel increase.
