Jog Mode - Beckhoff AX2000 Setup Manual

BECKHOFF
Direction of motion
ASCII: DREF
Determines the direction of motion for homing. The setting "distance-dependent" is only relevant for Homing 5
(within one turn). In this case, the direction is chosen to give the shortest distance to the zero-mark. This
parameter also defines the direction of motion for a Modulo type of axis.
v for homing
ASCII: VREF
Determines the velocity for the homing operation. The sign is automatically fixed by the direction of motion that
is selected. The dimension is set by VUNIT .
Accel. ramp
ASCII: ACCR
The acceleration ramp for the homing operation. The dimension is set by ACCUNIT. Entry e.g. in milliseconds
(1 ... 32767 ms). The ramp is also valid for constant velocity mode.
Decel. ramp
ASCII: DECR
The deceleration (braking) ramp for homing. The dimension can be set by ACCUNIT. Entry e.g. in milliseconds
(1 ... 32767 ms). The ramp is also valid for constant velocity mode. This deceleration ramp is only used if the
operating mode allows it. For homing to a hardware limit-switch, the emergency ramp is used.
Offset
ASCII: ROFFS
With the reference offset you can assign an absolute position value other than 0 to the reference point. With an
offset for the reference position you are not actually making a physical change, but the offset is used as a
reference value within the position control of the servo amplifier. Homing to the reference switch will then not
finish at zero, but at the preset reference offset value. The reference offset must be set before homing is
started. The dimension is set by PUNIT. An alteration of the offset only takes effect after a new homing
operation.
The parameter "Resolution" must be set correctly for your application.

Jog mode

Jog mode is defined as an endless motion at a constant velocity. This type of operation can be started without a
reference point being set. The hardware limit-switches are monitored. Software limit-switches are only
monitored if a reference point has been set. Acceleration and deceleration ramps are taken from the settings for
homing.
v
ASCII: VJOG
Determines the velocity for jog mode. The sign that is entered determines the direction of movement. Before
starting the jog mode, the velocity value must be taken on. The dimension is set by VUNIT .
F4
ASCII: MJOG
Start the jog mode by pressing the function key F4. The drive moves with the preset velocity in the direction,
which is indicated by the sign of the velocity for the jog mode "v", as long as the function key is pressed. If a
communication error occurs while pressing the button, the drive stops with the emergency deceleration ramp.
When the function "Jog mode" is started, the SW-enable is set automatically. The
Function "Jog mode" is only started in OPMODE 8. However, the SW-enable is set
in all OPMODES. The drive can therefore be accelerated by an analog setpoint that
is applied, if the START command is executed in OPMODES1 or 3.
