z Set the backlash error offset to 0 before measuring:
z Run the program by single blocks, search the measuring benchmark after 2 positioning
operations, record the current data, move 1mm in the same direction, then move 1mm to
point B reversely, read the current data.
Fig. 4-4 Schematic map of backlash measuring method
z Backlash error offset value= | data of point A –data of point B |; then input its outcome to the
data parameter
No.034(BKLX) ,No.035(BKLZ) ,No.180(BKLY) ,No.181(BKL4) ,No.182(BKL5) (multiply X
axis data to 2 and input the outcome to data parameter No.034).
Data A: dial-indicator data at point A
Data B: dial-indicator data at point B
Note 1: The backlash offset mode can be set by Bit7 of CNC parameter No.011; the backlash frequency can
be set by Bit6 of parameter No.011 and Bit4, Bit3, Bit2, Bit1, Bit0 of bit parameter No.010.
Note 2: Check the machine backlash every 3 months.
4.8 Tool Post Debugging
GSK980TDc supports various kinds of tool post, and the parameter settings are based on the
machine manual. The parameter settings for the tool post running are as follows:
BIT2(TSGN) of K parameter No.011: high/low level selection of tool post in-position signal, when
the signal is low level active, a parallel pull-up resistor is needed.
Bit3 (CTCP) of K parameter No.011: check/do not check tool post lock signal in tool change;
Bit4 (TCPS)of K parameter No.011: tool post lock signal HIGH/LOW selection;
Bit5 (CHET) of K parameter No.11: check/do not check tool signal;
Combinations and functions of tool change mode selection Bit1(CHTB), Bit0(CHTA) of K
parameter No.11 are referred to Tool Change Control .
Data parameter No.076: Duration for moving a tool in tool changing
Data parameter No.078: Upper limit time for changing one tool
Data parameter No.082: Delay time from tool post CCW stop to CW clamping start
Data parameter No.084: Total tools number
Data parameter No.085: Delay of tool post CW clamping
If the tool post doesn’t rotate at first power on for tool change, the phase connection of the
3-phase power of the tool post motor may be incorrect, it needs to press the RESET key immediately
and cutoff the power, then check the wiring; if the fault is caused by this, exchange two phases of the
3-phase power.
