DT34 Delay time after spindle auto gear shift in position
DT35 Check time of the auto gear shift
DT33: The initialization for 5 seconds, users can set the parameter to adjust it. but don’t set too short time
to cause the spindle damage due to little time for spindle switching in to lower gear stage; too long times
means
Timeliness is relatively low and processing efficiency affected.
DT34: The initialization for 5 seconds, users can set the parameter to adjust it, but don’t set too short time
that spindle cannot reach the appointed speed during the
M instruction implement; too long to affect
the
processing efficiency
.

Action sequence
The action sequence is as below according to control logic:
z
Control logic
¾ When K13.7 parameter set to 1, spindle auto gear shift function is valid;
¾
To implement any of M41,M42,M43,M44, judge input gear-stage is consistent with the current one
or not, else gear stage should shift;
¾ Gear shift starts, CNC outputs analog voltage set by parameterDT30 to spindle servo or frequency
converter;
¾ After a time set by parameterDT31(gear shift time1)
后
, shut gear-stage output signal and output
new gear shift signal;
¾ Check gear shift completed or not, if not, wait for complete signal;
¾ In a time set by DT33, if gear shift is not completed then perform alarm A1.0;
If gear shift is completed, delaying for a time set by parameter DT32(gear shift time 2), then CNC
outputs analog voltage set by parameterNO101
～
NO104, according to the current gear-stage. That
gear shift process is completed.
Note 1: only the number of spindle revolutions is in the analog voltage control, is the
spindle auto gear shift function valid;
Note 2: if spindle function is invalid, perform M41
～
M44 alarm;
Note 3: It needs checking in position signal that spindle gear shift function takes actions.
After having checked in position signal, the gear shift function can complete.
