Machine Data, Modes and Traversing Programs
5.3.2
Jog 2 (Mode 2)
Jog 2
Override 1 to 200%
Mode
Parameters
In essence, the "Jog 2" mode is identical to the "Jog 1" mode. The machine data
contains two speed values for this mode:
•
Jog 2 forward speed
•
Jog 2 reverse speed
The jog speeds for jog mode 1 and jog mode 2 need not be identical.
5.3.3
Jog under Open-Loop Control (Mode 3)
Jog under
Override 1 to 200%
Op.-Loop
Contol
Mode
Parameters
In this mode, axis travel is under open-loop control. Computation of the setpoint
position is disabled when this mode is started with
•
"Forward" or
•
"Reverse"
The setpoint position is now matched to the actual position. The result is a
following error of zero. The setpoint position is matched at the speed defined in
the machine data for Jog 2 mode. This value can be varied from 1 to 200% via the
Override factor. The speed computed from the encoder signals is displayed on the
programmer.
If you invoked mode 73 before starting Jog 2 mode, the distance to go is
displayed.
Note:
The IP 266 needs correct data for the drive system (encoder, axis) to attain the
speed displayed. Incorrect machine data will result in incorrect computation of
the actual value.
