(1) The spindle rotation direction control (CW/CCW)
When applying this function, parameter TCW/CWM (3706#7, #6) can not be
used. Please, always set both of parameter TCW (3706#7) and CWM (3706#6)
As for the spindle rotation direction, please control CW/CCW command signal
SFRx/SRVx <G070#5/#4, G074#5/#4, G204#5/#4, G266#5/#4 … > by ladder
program. And, please pay attention to serial spindle parameters. For example
(2) Canned cycles for drilling (G83 - G89)
The canned cycles for drilling includes the one, which outputs
M03/M04/M05/M19 automatically. When using such canned cycles for drilling,
parameter MPA (3706#2) must be set.
And, you must select the spindle to control in the canned cycle by commanding
spindle select P code before executing a canned cycle. The spindle select P
code must be commanded with the spindle function M code or the S command.
In case that the parameter MPA (3706#2) is 0, when executing the canned
cycles for drilling which outputs M03/04/05/19, alarm 5305 occurs.
(By the way, the P code command in the canned cycles for drilling becomes
dwell time specification.)
(3) Unavailable functions
When applying this function, the following function can not be used.
Manual numerical command ( = Option function）
(4) Multiple command of auxiliary function
When using Multiple command of auxiliary function (M code 3 pair) (= M3B:
3404#7=1), please be careful of the following.
Please set equal to or less than 65535 values to parameters 13550 -
When doing a command like the following example, each M code is
changed into the M code for the spindle which is chosen with the P code.
And then, a changed value is output to each signal.
- M03 M04 M05 P11;
- M19 M04 P12;
Please use M code group checking function to avoid that a command like
the above is executed.
(5) The function which decides the M code for the command by the parameter
There is a function which decides the M code for the command by the parameter
- Spindle positioning (Parameter 4960, 4961, 4962)
- Rigid tapping (Parameter 5210, 5212)
- And so on
When using such a function, set a value except spindle function M code (M03,
M04, M05 and M19).
