Torsion controller assembly

This enclosure contains the electronics required 
to drive the torsion motor and provide rotational 
feedback to the testing software. The front panel 
contains three LEDs. All three LEDs must be 
illuminated green for testing to begin.
Refer to 

“Torsion controller assembly” 

on 

page

20

 for more details.

3

Biaxial base mounting

Refer to the installation instructions supplied 
with the biaxial base mounting.

4

Torsion-specific handset

See 

Figure 3

 on page

15

.

5

Extended travel top plate

Dual column frames only (

Figure 2

).

The top plate is adapted to allow the torsion drive 
assembly to move through it. This means that the 
overall effective height of the frame is increased 
(refer to 

“Specifications” 

on page
