If the actual speed entered in machine data
S
MD36060: STANDSTILL_VELO_TOL (maximum velocity/speed for "axis/
spindle stopped")
falls below the programmed velocity/speed, the interface signal
S
IS DB31,... DBX61.4 (axis/spindle stopped)
is set. If
S
MD 35110: SPIND_STOPPED_AT_IPO_START (feed enable for "Spindle
stopped") is set,
the path feed is enabled.
If the spindle reaches the tolerance range specified in machine data
S
MD35150: SPIND_DES_VELO_TOL (spindle speed tolerance)
the interface signal
S
IS DB31,... DBX83.5 (spindle in setpoint range)
is set. If
S
MD 35110: SPIND_STOPPED_AT_IPO_START (feed enable for "Spindle
stopped") is set,
the path feed is enabled.
The maximum spindle speed is entered in machine data
S
MD35100: SPIND_VELO_LIMIT (maximum spindle speed).
The NC limits the spindle speed to this value.
Error response
If the speed is nevertheless exceeded by the speed tolerance (drive error), the
following signal is output:
S
IS DB31,... DBX83.0 (speed limit exceeded) = 1
S
Alarm "22150 Maximum number of chucks exceeded"
