（
Standard PLC program definition
）
①
M20 and M21 are a pair of M commands for controlling the spindle clamp and release, and
they are for clamping the spindle after positioning, so that the spindle won’t rotate due to the
force during drilling or tapping.
② During executing M20, to avoid the clamped spindle servo motor current too big, CNC will
control the spindle and cut off the servo after the delay time set by DT23, and then, the
spindle servo reduces the motor excitation, while the position control can’t be executed.
However the position detection can still functions and the position won’t get lost.
③
The spindle can’t be clamped by M20 during the spindle moving or rotating. After the spindle
is clamped, the spindle can neither be rotated nor moved; otherwise, PLC issues the alarm.
