4-16165988-1CDHW1481991Safety Board Operation 4 Details of Functional Safety Function4.2 AXIS SPEED MONITOR Function3.{SPEED}To each object axis, set the upper limit of motion speed.When the axis is a rotating axis, it is measured in [deg/sec], and is[mm/sec] when the axis is a direct acting axis.4.{ACCEP. RNG}When “0” is set to {SPEED}, setting a value to this item becomespossible.This item is used when the axis is in the stop position monitoring status.The stop position monitoring operation judges that the axis is notmoving by monitoring the object axis position difference between thestop position monitoring starting position and the present position.To avoid any alarms from occurring due to tiny motions such as turningON of the servo during the monitoring, this item is set.An alarm occurs when {ACCEP.RNG} is set in ± direction from the stopposition monitoring starting position and the axis moves to exceed theposition.When the axis is a rotating axis, it is measured in [deg], and is [mm]when the axis is a direct acting axis.When ”0” is set to {ACCEP.RNG}, as default values, 0.2 [deg] is used forthe rotating axis and 20 [mm] is used for the direct acting axis.4.2.4 Start AXIS SPEED MONITOR OperationAfter values are input to {SPEED} and press {WRITE} button on thewindow, “COMPLETED” appears to {FILE SET STATUS}. The axis speedmonitor function becomes possible to execute.48 of 164
