Description
Axis technology object
Start of the command with a positive edge. Default value:
FALSE
TRUE = Change ramp-up time in line with input parameter
"RampUpTime". Default value: FALSE
Time (in seconds) to accelerate from standstill to the configured
maximum velocity without jerk limit. Default value: 5.00
The change will influence the tag <Axis name>.
Config.DynamicDefaults.Acceleration. The effectiveness of the
change is shown in the description of this tag.
TRUE = Change ramp-down time in line with input parameter
"RampDownTime". Default value: FALSE
Time (in seconds) to decelerate axis from the configured
maximum velocity to standstill without jerk limiter. Default value:
5.00
The change will influence the tag <Axis name>.
Config.DynamicDefaults.Deceleration. The effectiveness of the
change is shown in the description of this tag.
TRUE = Change emergency stop ramp-down time in line with
input parameter "EmergencyRampTime" Default value: FALSE
Time (in seconds) to decelerate the axis from configured
maximum velocity to standstill without jerk limiter in emergency
stop mode. Default value: 2.00
The change will influence the tag <Axis name>.
Config.DynamicDefaults.EmergencyDeceleration. The
effectiveness of the change is shown in the description of this
tag.
TRUE = Change smoothing time according to the input
parameter "JerkTime". Default value: FALSE
Smoothing time (in seconds) used for the axis acceleration and
deceleration ramps. Default value: 0.25
The change will influence the tag <Axis name>.
Config.DynamicDefaults.Jerk. The effectiveness of the change is
shown in the description of this tag.
TRUE = The changed values have been written to the
technology data block. The description of the tags will show
when the change becomes effective. Default value: FALSE
TRUE = An error occurred during execution of the command.
The cause of the error can be found in parameters "ErrorID" and
"ErrorInfo". Default value: FALSE
Error identifier. Default value: 16#0000
Error information. Default value: 16#0000
