B-63790EN/01 4.DESCRIPTION OF PARAMETERS
- 115 -
1645 Parameter 2 to set acceleration/deceleration for each axis when a constant
feedrate command for PMC axis control is specified
[Input type] Parameter input
[Data type] Integer axis
[Unit of data] msec
[Valid data range] 0 - 32767
Specify the time it takes to reach the feedrate set in parameter 1.
NOTE
When this parameter is set to 0, the
acceleration/deceleration function is disabled.
1656 Acceleration change time of bell-shaped acceleration/deceleration before
interpolation
[Input type] Parameter input
[Data type] Integer
[Unit of data] msec
[Valid data range] 0 - 200
This parameter sets the acceleration change period in bell-shaped
acceleration/deceleration before interpolation (the time taken for the
change from the constant speed state (A) to the certain
acceleration/deceleration state (C) using an acceleration calculated
based on the acceleration set in parameter No. 1660: the period of (B)
in the following figure) .
Tangential feedrate
Optimum inclination is automatically
calculated based on the value set in
parameter No. 1660.
Set the period in parameter No.
1656.
