4) Acceleration [G] ······· Set the acceleration at start.
5) Deceleration [G] ······· Set the deceleration at stop.
(Reference)How to set the acceleration is described below. The same idea
can be applied to the deceleration.
1G = 9800mm/s 2 : Accelerated to 9800mm/s per second
0.3G: Accelerated to 9800mm/s × 0.3 = 2940mm/s per second
Caution: (1) Set the velocity, acceleration and deceleration so that they do not
exceed the rating values described in the brochure or the instruction
manual of the actuator. Failure to follow this may cause the life of the
actuator to be shortened extremely.
(2) If shocks and/or vibrations appear on the actuator and/or the work,
lower the acceleration and/or the deceleration. In such cases, do not
continue the use of the actuator, otherwise the product life may be
shortened extremely fast.
(3) If the carriage weight is extremely lighter than the rating carriage
weight, acceleration/deceleration larger than their rating values to
shorten the cycle time. Please contact IAI for the settings in such
situation. Inform us of the weight, shape and mounting method of the
work and the installation conditions of the actuator.
6) Pressing [%]············· Setting proper data here allows pressing to be done. Set a pressing
torque (limit current value) in %. If the value is set to 0, the normal
positioning operation is performed.
The speed for the pressing operation is set in Parameter No.34.
If the setting of 3) is lower than the pressing velocity, the pressing
process will be conducted with the velocity of 3).
Caution: If the pressing velocity is changed, the pressing force may differ from that
specified in “1.2.1 Actuator”.
When the pressing velocity is changed, make sure to measure the actual
pressing force before start using.
7) Threshold [%]··········· Unavailable. Do not set up.
