To fix alarms for the X-axis driver not ready, Y-axis, Z-axis, and emergency stop on the GSK980MDc system, follow these steps:

1. Check Emergency Stop (ESP) Alarm:
- Ensure the emergency stop button is not pressed.
- Verify the CNC diagnostic message ESP to monitor the state of the emergency stop input signal.
- If the alarm persists, press the Overtravel Release button and move the axis in the reverse direction.

2. Stroke Limit Switch Check:
- In Manual or MPG mode, slowly move the axes to test the stroke limit switch.
- Confirm the correctness of the alarm display and the validity of the overtravel release button.
- Adjust the stroke limit switches if necessary.

3. Drive Unit Setting:
- Set BIT4 to BIT0 of bit parameter No.009 according to the alarm logic level of the drive unit.
- For the system’s default drive unit, all bits (BIT4–BIT0) of parameter No.009 should be set to 1.

4. Check Connections:
- Ensure the X, Y, and Z-axis drive units are properly connected and powered.
- Inspect wiring and connections for any loose or damaged cables.

5. Restart the System:
- After making adjustments, restart the CNC system and check if the alarms clear.

This procedure should help resolve the alarms related to the X, Y, Z-axis driver not ready and emergency stop.

Chapter 4 Control Function of Additional Axis The process of zero return 1. Select the machine zero return mode and press the manual positive feed key, the corresponding axis moves toward the zero point at the rapid traverse rate. 2. When the one-turn signal (PC) of servo axis is carried out, the system is decelerated to the zero return low speed, in this case, check the trailing edge of PC signal.
Page 145 GSK980MDc Milling CNC System User Manual Set Cs contour control axis In the 980MDc system, only the additional axis (the 4 or the 5 axis) can be set to a Cs contour control axis. But, two Cs axes can not be set at the same time. Before the Cs axis setting is valid, this axis must be set to a rotation axis.
Page 146 Chapter 4 Control Function of Additional Axis The zero return of Cs axis is performed opening the feed axis and the direction selection signal ＋Jn (G100) or －Jn (G102). Automatic Specify G28 after the spindle enters the Cs contour control mode, and the spindle moves to the intermediate point and then return to the reference position.

Chapter 5 Macro Program CHAPTER 5 MACRO PROGRAM GSK980MDc provides macro programs which is similar to high level language. Variable assignment, arithmetic operation, logical judgment and conditional branch can be realized through custom macro program. It is in favor of the programming for special parts, lessens the complex operation and simplifies the custom program.

Page 420: Appendix 10 Analog Spindle Function
Appendix Appendix 10 Analog Spindle Function The spindle is classified into mechanical spindle and analog spindle, according to the way how CNC control the spindle. To mechanical spindle, CNC controls its speed by inputting the switch values which are changed from S codes, into the spindle; to analog spindle, CNC changes S codes into analog values which are inputted to the spindle to control the speed.CNC informs the PLC of the current spindle control mode by issuing SIMSPL signal.

The signal sets S instructions in NC to 0, showing as the sequence chart below: ●Note: When spindle stop signal*SSTP is 0, output voltage turns to 0.
Page 432 Appendix ●Note: instruction setting non-zero speed output to spindle, NC turns F1.4 to 1; when speed instruction is 0, then the ENB signal is set 0. In analog spindle, spindle motor will rotate in a low speed in spite of NC outputs instruction 0 to the spindle (namely, analog voltage is 0V), because the frequency converter has a drift voltage.
Page 433 GSK980MDc Milling CNC System User Manual ●Signal Type: PLC→NC ●Signal Function: when the PLC makes G29.4 set to 1, passes to NC, to notify the NC, the NC can start cutting feed. When G29.4 is 0, cutting feed is not started. ●Note: Generally, this signal is used to notify the CNC that spindle has arrived to the appointed speed.
