Supplementary explanation

 It becomes spindle phase synchronous control by G51.8 command with address R. When the error

pulse difference between the two spindles is equal to or less than the value of parameter No.4810,

spindle phase synchronous control completion signal is output.

Spindle phase synchronous position is available to set at the parameter No.4034 for each master and

slave spindle. Phase shift amount that is commanded by address R in G51.8 command is valid to one

of the master spindle and the slave spindle. Which spindle that is valid phase shift was chosen from

the master spindle or the slave spindle by parameter No.4802#- SYR.

It is not available to keep synchronous condition between two spindles in spindle phase synchronous

motion (until set spindle phase synchronous control completion signal FSPPH <F044#4>to 1).

So, do not execute spindle phase synchronous control in condition of the work was clamed by both two

spindles.

 It is prepared the PMC DO signal F044#4 SYCAL that is effective to observe pulse difference between

two spindles in already completion mode of spindle synchronous control or spindle phase synchronous

control. This signal set to 1 on condition error difference between two spindles is equal to or above the

value of parameter No.4811 that is set absolute value of error pulse difference on master spindle side,

and the signal set to 0 if error difference is less than the value of parameter by observation error

difference of spindle synchronous control.

 It is available to use constant surface control in condition of the work was clamped by both two

spindles in spindle synchronous control.

However if the change of spindle speed is generated above than time constant, the spindle speed will

change by time constant that was defined by parameter

 The maximum spindle speed of synchronous control is defined by maximum spindle speed (parameter

No.4020) of master spindle.

(Example) The maximum spindle speed of master spindle : 6000rpm

The maximum spindle speed of slave spindle : 4500 rpm

In the above case, maximum spindle seed of master spindle is 6000rpm for the spindle command

12bit=4096. If you command spindle speed 6000rpm in spindle synchronous control mode, the slave

spindle become over heat alarm. So please do not command above 6000rpm for spindle speed in the

above condition.

The maximum spindle speed of spindle synchronous control become lower maximum spindle speed of

master spindle or maximum spindle speed of slave spindle by parameter No.4800#4 SYM.

Page 21. Outline This function enables the synchronous control of two spindles. It also enables the control of rotation phase of a spindle, allowing non-standard workpieces as well as rods to be held by either of the two spindles.
