4.1 Parameters
Four parameters are available: Basic parameters 1 and 2, detailed parameters 1 and
2.
This is basic data determined by the mechanical system to allow the QD75 to perform
the positioning control.
4.1.1 Basic parameters
Basic parameters are subdivided into basic parameter 1 and 2.

(1) The initial value is the same for axis 1 to 4.
(2) When the sequence program is used for making the settings, a decimal point
cannot be used.
(3) Acceleration time 1 to 3 and deceleration time 1 to 3 are in the detailed
parameters.
