Operation
(No.100, No.101) or G22; the inner prohibition/outer forhibition of the setting range are set
by Bit 2 of parameter No.172. This limit is enabled when the G22 is at the current modal, and
the limit is disabled when the modal is G23. Refer to the program help G22/G23 command.
4) Stored stroke limit detection 3: The limit area boundary is set by parameter (No.102,
No.103); the inner side of the setting range is limit area.
5) Whether the axis is performed the limit inspection: Bit 2 of parameter No.190 and Bit 3 of
parameter No.190 can be set an axis whether it performs the stored stroke inspection 2 or 3.
The stored stroke inspectin 2 or 3 is only judged the axis from the inspection. For example:
When X or Z axis performs the judgement, and the Y axis does not, only detect whether the
X or Z axis enters to the limit area.
6) Zero return enabled: When the state parameter Bit 1 of No. 172 sets to 1, it needs to return
the reference position by manual or G28 after the power is turned on, the function is then
enabled accordingly. After an axis is performed the zero return for the external limit area,
and the limit area of this axis is immediately enabled; it is disabled of the axis that does not
perform the zero return. For the inner limit area, the limit function is enabled after the overall
axes executed the detection are performed the zero return.
7) Limit deceleration: State parameter Bit 0 of No.172 can be set a stop method when it
reaches to the limit boundary. Deceleration stop near the forbidden area or immediately stop
after entering to the forbidden area can be selected.
Note 1
：
If the positive stroke is less than or equals to the negative one in the setting forbidden area, the area is
shown below:
１）
When the forbidden area is the stored stroke inspection 1 or the 2 from the external prohibition, the
overall areas are treated as the forbidden area.
２）
When the forbidden area is the stored stroke inspection 3 or the 2 from the internal prohibition, the
overall areas are regarded as the moveable areas.
Note 2
：
An alarm may occur if the reference position locates within the limit area when returning the reference
position.
2.4 Emergency Operation
During the machining, some unexpected incidents may occur because of the user programming,
operation and product fault etc. So the GSK980TDi should be stopped immediately for these
incidents. This section mainly describes the resolutions that the system is capable of under the
emergency situation. Please see the relative explanation on these resolutions under the emergency
by machine manufacturer.
2.4.1 Reset
Press
key to reset GSK980TDi system when there are abnormal output and axis
operations:
1 All axes motion stops;
2 M, S function output is inactive (the parameter sets whether the system automatically cuts off
signals of spindle rotation, lubricating, cooling by pressing
key, defined by PLC ladder);
3 Automatic run ends, modal function and state remain.
