(2)   Control details 
(a)   The roller has no current value. 
However, when it switches from the virtual mode to real mode, it reaches the 
current value corresponding to the position moved in the virtual mode. 
• The current value is a ring address within the range of -2147483648 (-2
31
) 
to 2147483647 (2
31
-1) [PLS].

(b)   Backlash compensation processing is continued with the settings value of 
fixed parameters even if it switches the real mode/virtual mode. 
 
(c)   The roller cycle speed can be monitored using MT Developer2 and the roller 
cycle speed storage register. 
Refer to Section 8.1.2 for the calculation formula of roller cycle speed, and 
refer to Section 4.2.1 for details of the roller cycle speed storage register. 
 
8.1.2 Parameter list 
The roller parameters are shown in Table 8.1 and the parameters shown in this table 
are explained in items (1) to (6) below. 
Refer to the help of MT Developer2 for the roller parameter setting method.

(1)   Output unit 
(a)   This device is used to set the unit ([mm]/[inch]) of roller. 
 
(b)   The unit (unit in the fixed parameter) for the axis which execute the roller 
setting in the real mode is permissible to use the any of [mm], [inch], 
[degree] and [PLS].
