Operation
Continuous Operation Mode
In this mode, the Position Driver stays in continuous operation without being stopped in servo-lock.
Until the continuous operation mode specification is canceled (i.e., until the mode changes into inde-
pendent operation mode or automatic incremental mode), the Position Driver continues operating and
refreshing the present point number.
P.OUT0 to P.OUT6 are refreshed whenever the present point number changes.

Precautions when Using Continuous Operation Mode with Feeder Control
With feeder control (UP-01: 12), positioning is executed with the present value at the time the start
signal turns ON taken as the reference (origin).
If the Position Driver is in continuous operation mode, the present value will be set to 0 at the moment
the start signal is turned ON after the point number is input. The present value cannot be cleared, how-
ever, if the next positioning is performed because the start signal is not input in that case. Therefore, for
example, make the following settings for a high-speed feed distance of 900 mm followed by a low-
speed feed distance of 100 mm.
Setting Example 1
Point number 1 = "I + 900.000," continuous operation mode
Point number 2 = "I + 100.000," independent operation mode
Setting Example 2
Point number 1 = "I + 900.000," continuous operation mode
Point number 2 = "A + 1,000.000," independent operation mode
Note In these examples, PP-01 is set to 0.001 for the minimum setting unit.
Point output
Note 1. There is no difference in operation between the data attributes "I" and "A" at point number 1.
Note 2. The operation at point number 2 varies according to the data attribute (I/A) setting.
