Additional Manual
Master spindle and slave spindle of spindle synchronous control was set in parameter No.1812 and
No.1813. It is available to set 1 pair of master spindle and slave spindle that is performed spindle
synchronous control on each path.
PMC DO signal PSYON (F0348#0) is outputted by G51.8 command. Please operate PMC signal about
spindle synchronous control by using PSYON signal. When operation of PMC signal is finished, please
set to 1 PMC DI signal PSYFN (F0348#0). Spindle synchronous control will start by PSYFN signal.

  • 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. Spindle synchronous control has two control ways, ones is contoroles by PMC

If you need to change phase shift amount in condition of spindle phase synchronous control mode, please execute G51.8 R_ command again. It it not able to use spindle synchronous

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 synch

Also it is available to use PMC signal SIND, SSIN, SSGN, R01I-R12I,*SSTP,SOR etc as usual. You can control spindle speed from PM

Signal Spindle synchronous control signal SPSYC [Classification] Input signal [Function] Specifies switching to spindle synchronization mode [Operation] When this signal set to 1, spindle synchronization mode is set. When this signal set to 0, spindle synchronization mode is cancelled. Note This
  • Page 10NOTE 1. When the two spindles seize the same workpiece, a spindle may be fixed at a position slightly displaced from the specified position because the two spindles are mechanically connected. In this case, an excessively high current can flow because the velocity loop integral function attempts to

On spindle synchronous control by program command function (G51.8), turn on this signal to release spindle synchronous control from PMC signal. [Operation] When t

The two spindles have not reached the speed corresponding to a specified spindle synchronous speed on spindle synchronization mode. The speed difference between the two spindles is greater than the value set in parameter No.4033
  • Page 13Note Even if this signal is set to 1 once, this signal is set to 0 when the speed difference becomes equal to or greater than the value set in parameter No.4033 for a cause such as cutting load variation.
