Caution
The part programmer must ensure that one of the following maintenance conditions
occurs for WAITS.
- Position reached
- Spindle stationary
- Spindle up to programmed speed
In cases where one spindle is used in several channels, the part programmer must
ensure that WAITS starts at the earliest in the phase in which the spindle of another
channel has already started to accelerate or decelerate towards the new speed or
direction of rotation.
• WAITS instructions are used for coordination in the part program:
WAITS
For main spindle (master spindle)
WAITS[n]
For main and other spindles
WAITS[n, m,...,q]
For several spindles up to the maximum number of spindles
The control waits before executing subsequent blocks until:
Position(s) programmed with
SPOSA
Are reached.
M5
The spindle is stationary.
NC/PLC IS:
DB31, ... DBX61.4 (spindle stationary)
taking the tolerance:
MD36060 $MA_STANDSTILL_VELO_TOL into account.
WAITS is terminated and the next block loaded when the first
occurrence of the signal is detected.
M3, M4 (speed control mode) The speed is in the setpoint range.
NC/PLC IS:
DB31, ... DBX83.5 (spindle in setpoint range)
Tolerance:
MD35150 $MA_SPIND_DES_VELO_TOL
WAITS is terminated and the next block loaded when the first
occurrence of the signal is detected.
This function of WAITS applies in the programmed channel.
WAITS can be used to wait for all spindles known to this channel,
although spindles may also have been started in other channels.
