Jog and Stepping Mode
The drive can be run manually at the defined setup speed when the Jog mode
is active. Control is implemented via Direction_Pos or Direction_Neg. The
two control bits are locked against each other. The run is ended when the set
timeout period (stepping mode) expires via the process image. A timeout of
zero allows unlimited movement, as long as Direction_Pos or Direction_Neg
is set (Jog mode).
If the setup speed is parameterized as zero, the Jog mode is run at speed 1.
If movement is made to a limit switch during the Jog mode, the drive will
stop. After that, movement can only be made away from the limit switch.
The drive stops when it leaves the movement range defined by the parameter
Drive_Range_Neg and Drive_Range_Pos. The drive can then be operated
outside the movement range using a repeated JOG command.
