14.3.14 Spindle winding changing
Spindle winding changing is allowed via the spindle drive by the command form PLC
according to YS 840DI system specification.
Changing process
For example, the changing procedure with spindle speed detection signal (DBX94.5) is
shown below.
1. Set the spindle speed detection speed (MD6401 (Cn401)) for the winding changing
speed SCHW.
2. Set the spindle speed detection width (MD6402 (Cn402)) for the winding changing
speed hysteresis range
Δ
S.
MD6401, MD6402: Set the value in the units of 0.01 % of the rated revolution.
3. PLC detects ON/OFF for the spindle speed winding signal with DBX94.5.
4. PLC instructs the low-speed winding selection (DBX21.3 = 0, DBX21.4 = 0), and the
high-speed winding selection (DBX21.3 = 1, DBX21.4=0). (Switching command is per-
mitted with DBX21.5.)
5. PLC checks the winding selection status (DBX 93.3-4 agree with DBX 21.3.4) sent
from CNC and completes the process.
An example of time chart in case that switching speed is 1250min
-1
is shown below.
