Coordination actions in the part program have the following advantages:● The part program author can decide at what point in the program the spindle needs to beup to speed, e.g. in order to start machining a workpiece.● This avoids unnecessary delays.Coordination in the part program involves programming the WAITS command:WAITS: for main spindle (master spindle)WAITS[]: for spindles with number WAITS[,,...]: for several spindles up to the maximum number of spindlesCAUTIONCoordination errorThe part program author must ensure that one of the following maintenance conditions occursfor WAITS.● Position reached● Spindle stationary● Spindle up to programmed speedIn cases where one spindle is used in several channels, the part program author must ensurethat WAITS starts at the earliest in the phase in which the spindle from another channel hasalready started to accelerate or decelerate towards the required new speed or direction ofrotation.The control waits before executing subsequent blocks until:● Position(s) programmed with SPOSA are reached.● Spindle standstill is reached with M5:DB31, ..., DBX 61.4 (spindle stationary)taking into account the tolerance:MD36060 $MA_STANDSTILL_VELO_TOLWAITS is terminated and the next block loaded when the first occurrence of the signal isdetected.● In M3/M4 (speed control mode), the speed in the setpoint range is:DB31, ..., DBX83.5 (spindle in setpoint range)taking into account the tolerance:MD35150 $MA_SPIND_DES_VELO_TOLWAITS is terminated and the next block loaded when the first occurrence of the signal isdetected.This WAITS function applies in the programmed channel.WAITS can be used to wait for all spindles known to this channel, although spindles mayalso have been started in other channels.S1: Spindles16.2 ModesBasic Functions1210 Function Manual, 01/2015, 6FC5397-0BP40-5BA2
