Parameter and type
Data type
Description
Velocity IN Real Preset velocity for jog mode (Default value: 10.0)
Limit values: Start/stop velocity ≤ |Velocity| ≤ maximum velocity
InVelocity
OUT
Bool
TRUE = The velocity specified in parameter "Velocity" was reached.
Busy
OUT
Bool
TRUE = The task is being executed.
CommandAborted
OUT
Bool
TRUE = During execution the task was aborted by another task.
Error OUT Bool TRUE = An error has occurred during execution of the task. The
cause of the error can be found in parameters "ErrorID" and
"ErrorInfo".
ErrorID
OUT
Word
Error ID for parameter "Error" (Default value: 0000)
ErrorInfo
OUT
Word
Error info ID for parameter "ErrorID" (Default value: 0000)

If both the JogForward and JogBackward parameters are simultaneously TRUE, the axis stops with the configured
deceleration. An error is indicated in parameters "Error", "ErrorID", and "ErrorInfo".
The following values were configured in the "Dynamics > General" configuration window: Acceleration = 10.0 and
Deceleration = 5.0
①
The axis is moved in the positive direction in jog mode via "Jog_F". When the target velocity 50.0 is reached, this is
signaled via "InVelo_1". The axis brakes to a standstill again after Jog_F is reset.
②
The axis is moved in the negative direction in jog mode via "Jog_B". When the target velocity 50.0 is reached, this
is signaled via "InVelo_1". The axis brakes to a standstill again after Jog_B is reset.
Override response
The MC_MoveJog task can be aborted by
the following motion control tasks:
•
MC_Home Mode = 3
•
MC_Halt
•
MC_MoveAbsolute
•
MC_MoveRelative
•
MC_MoveVelocity
•
MC_MoveJog
The new MC_MoveJog task aborts the
following active motion control tasks:
•
MC_Home Mode = 3
•
MC_Halt
•
MC_MoveAbsolute
•
MC_MoveRelative
•
MC_MoveVelocity
•
MC_MoveJog
