(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

Current value
(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 Developer 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 Developer 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].
