Command Parameters
# Parameter Description
Range
1 Requested Output (V)
-10≤V≤10
2 Output Ramp Rate (V/sec)
>0
Description
This command switches the axis to open loop control and ramps the Control Output
linearly to the Requested Output at the rate specified in the Output Ramp Rate. This
command will not be affected by any errors on the axis. If an error bit turns on, the
Control Output will still be the value as commanded by this command.
This command turns on the Direct Output Status bit.
Note:
This command is identical to the Open Loop Rate (10) command, except that this command
disables all auto stops until another motion command is issued. As such, this command is
intended for testing the Control Output and not for actual motion control. For motion
control, the Open Loop Rate (10) command should be used instead.
Default Ramp Rate
When choosing the open Loop rate command in the Command Tool, a User Program, or
Shortcut Commands, the default value of the Ramp Rate is 100 V/sec. You should
