Operation
After the rapid movement switch is pressed, the machine tool is moved at the rapid
traverse rate (#1424 parameter) no matter where the position of the manual feedrate override dial is,
and the function is called as the manual rapid movement. Many axes can be moved meanwhile in
Manual mode.
Manual feeding steps:
（ 1 ） Press the manual continuous switch , and it is one of the mode selection switches;
（ 2 ） Press the feeding axis and the direction selection switch , the machine
tool is moved along the corresponding direction of the corresponding axis. After the switch
is pressed, the machine tool is moved at the feedrate set by the parameter (#1423); after
the machine tool is released, the machine tool feeding stops;

The manual continuous feedrate is adjusted by the manual continuous feedrate override
dial;
（ 4 ） If the rapid traverse switch is pressed when the feeding axis and the direction
selection switches are pressed, the machine tool is moved at the rapid traverse rate when
the rapid traverse switch is pressed, and the rapid movement override
is valid during rapid traverse;
The above mentioned is one example, please refer to the user manual from the machine tool
builder for operation.
Note 1: Acceleration/deceleration: the manual rapid traverse rate, the time constant of
acceleration/deceleration and the acceleration/ deceleration mode can be set by the parameters 1610
and 1624.
Note 2: Changing the mode: during manual feeding, the manual feeding is invalid when the mode is switched
into the other mode. The manual feeding mode is entered firstly, and then the feeding axis and the
mode selection switches are pressed, and then, the manual feeding is valid.
Note 3: Rapid movement before reference position return: if the reference position return isn’t executed after
power on, the button of “rapid traverse” is pressed, the rapid movement can’t be executed while the
manual continuous movement is maintained. The function is set by the parameter RPD (bit 0 of
#1401).
Note 4: Whether the manual override is valid in Manual mode is set by bit 2 of parameter 1402, and the
override is fixed as 100% when the manual override is invalid.
