POINT
Operation parameter group 1 automatic operation speed (aux_Aspeed1) functions as clamp speed in all operations.
A feedrate exceeding aux_Aspeed1 cannot be commanded.
Setting the acceleration/deceleration pattern and time constant
Set the automatic operation mode acceleration/deceleration type in the parameter "#1361 aux_acc".
 Acceleration/deceleration with constant time: When "#1361 aux_acc"= "0"
Acceleration/deceleration pattern will be fixed with the time constant aux_timeN.1 and aux_timeN.2 in operation parameter
group N (N= 1 to 4).
 Acceleration/deceleration with a constant angle of inclination: When "#1361 aux_acc" = "1"
Acceleration/deceleration pattern will be with the inclination decided by "Operation parameter group 1 automatic operation
speed" (#12810 aux_Aspeed1) and "Acceleration/deceleration time constant 1, 2" (aux_timeN.1, aux_timeN.2) in the oper-
ation parameter group N (N= 1 to 4).
Set the automatic operation mode acceleration/deceleration pattern in "Operation parameter group N acceleration/
deceleration type" (aux_smgstN).
 Linear acceleration/deceleration: Set "1" in "#128N8 aux_smgstN"
 S-pattern acceleration/deceleration: Set "F" in "#128N8 aux_smgstN"
However, when "Acceleration/deceleration time constant 2" (aux_timeN.2) is set to "1", linear acceleration/deceleration will be
applied regardless of "Acceleration/deceleration type" (aux_smgstN).
As for the acceleration/deceleration time constant in each of the groups, set a linear acceleration/deceleration time up to the
clamp speed (aux_Aspeed1) in "Acceleration/deceleration time constant 1" (aux_timeN.1). When the operation speed is less
than the clamp speed, acceleration/deceleration will be carried out with the same inclination. In this case, set "1" (default
value) in acceleration/deceleration time constant 2 (aux_time.2).
When S-pattern acceleration/deceleration is applied, set a total acceleration/deceleration time (both in non-linear and linear
parts) to "Acceleration/deceleration time constant 1", and set a acceleration/deceleration time in non-linear part to
"Acceleration/deceleration time constant 2".
Speed
(b) (c)
(a)
(a): Set value of acceleration/deceleration time constant 1
(b) +(c) : Set value of acceleration/deceleration time constant 2
When (b) is equal to (c), (b) and (c) are each half of the set value.
In handle feed mode, execute linear acceleration/deceleration using "Acceleration/deceleration time constant 2"
(aux_timeN.2) only.
