Note: If you are using a home limit switch and a home proximity limit
switch and a right to left home command is required to home the axis,
mount the home proximity limit switch to the right of the home limit
switch. If a left to right home command is required, mount the limit
switches opposite to the above. See the diagrams below to properly
locate the home limit switches.
Jog
+ / (CW) and Jog – / (CCW) commands.
This command causes the axis to operate in the jog mode, at the
programmed velocity and in the designated direction. If the velocity
specified for the jogging operation is below the programmed starting
speed, the starting speed is ignored. However, if the specified velocity
is above the starting speed, the axis jog move begins at the starting
speed, accelerates to the specified velocity and runs at that velocity
until one of the following occurs:
• The jog command bit is turned off.
• An external interrupt input is activated.
• The immediate stop output bit is set.
• The emergency stop input is activated.
When either the jog command is turned off or the external interrupt
input is activated, the axis decelerates to the starting speed and then
stops. The valid axis position is retained. If, however, either an
immediate stop output bit is set or the pulse train enable/disable input
is activated, the axis stops and the position is invalid.
One Shot Jog: When it is necessary to move the stepper motor while
one of the inputs is active, the jog bit can be made to cause the
