5.9.1.8. Jerk Smoothing Time (Pn2A6)
This parameter is used to define the default value of the jerk smoothing
time variable. This variable is used to define the jerk smoothing time of a
movement, i.e., it uses an average filter on the command pattern. For
example, if the command pattern is a trapeze, it will make it a S-curve
pattern.
Parameter Setting
(μs) Signal
Pn2A6
Range: 0 to 63999
Default setting: 0

5.9.1.9. Quick Stop Deceleration (Pn2A8, Pn2A9)
These parameters are used to define the deceleration of the motor when a
STOP command is issued.
Parameter Setting
Signal
Pn2A8
Range: 0 to 65535
Default setting: 65535
[User Acceleration units]
Deceleration of motor in
case of STOP command
Pn2A9
Range: 0 to 256
Default setting: 256
[User Acceleration units*65536]
Deceleration of motor in
case of STOP command
(high bits)
For example, for a deceleration of 200000 [Acceleration units], set the
following parameters:
• Pn2A8 = integer part of 200000/65536 = 3
• Pn2A9 = 200000 – 3*65536 = 3392
5.9.1.10. Motion End Window (Pn2C0)
This variable defines the default value of a window for position error to
finish a motion. In case of a MOVED motion, the next motion in buffer
will be executed after the command is finished and the position error (in
user units) will be smaller than the value of this variable.
