Operation
During the manual operation, many axes can move at the same time.
JOG feed steps:
1. Press and it is one of mode selection switches,
2. Press feeding axis and , the machine moves along the corresponding axis
in the corresponding direction. When the switch is pressed, the machine moves at the feedrate set by
parameter (#1423); once the switch is released, the machine stops feeding;
3. Manual continuous feedrate can be adjusted through the manual continuous feedrate override
dial;
4. If the feeding axis, the direction selection switch and are pressed meanwhile, the
machine moves at the rapid traverse speed, and can be selected and
valid during the rapid traverse;
The above is just one example; refer to the manual provided by the machine manufacturer during
actual operation.
Note 1: Acceleration/deceleration;
Manual rapid traverse speed, the time constant and the mode of acceleration/deceleration can be set
by parameter 1610 and 1624.
Note 2: Changing the mode:
During JOG feeding, when the mode is switched into the other mode, JOG feeding becomes invalid.
To make JOG feeding valid, firstly access JOG feeding mode, and then press feeding axis and mode
selection switch.
Note 3: Rapid traverse before the reference position return:
If the reference position doesn’t return after connecting the power supply, even press “rapid
traverse” button, it can’t run; while remain manual continuous feeding traverse. The function can be
set by parameter RPD (0 bit of #1401).
Note 4: In manual mode, whether JOG override is valid, which is set by the 2
nd
bit of parameter #1402; when it
is invalid, the override is fixed as 100%.
5.3 Increment Feeding
In JOG mode, during MPG or manual feeding, whether the increment feeding is valid, this is set
by parameter JHD (0 bit of #7100). The corresponding relation is shown as below:
JHD=0 JHD=1
