2.2.2 Rated load (mass capacity)
(1) The acceleration/deceleration must be set appropriately in the program according to the loaded load mass.
The relation of the optimum acceleration/deceleration in respect to the mass capacity is shown with a

Fig.2-1 ： Relation of mass capacity and optimum acceleration/deceleration percentage
Make sure that the acceleration/deceleration percentage satisfies the values in the shaded section shown in
2-1. The acceleration/deceleration percentage is set with the ACCEL command in the program. If the per -
Fig.
centage is not set in the program, the default value 100% will be set as the acceleration/deceleration percentage.
An example of setting in the program is shown below.
Example) When the loaded load mass is 1kg, the appropriate acceleration/deceleration percentage will be 50%,
as shown in

：
Details on the Accel command are given in section "4.14 Explanation of command words" in the separate man -
ual "Detailed explanations of functions and operations".
When using the optimum acceleration/deceleration function (when using the Oadl command), the optimum
acceleration/deceleration percentage will be set automatically according to the load state, so setting with the
Accel command is not required.
