(b) Speed monitoring parameter
Set the even number as the Multiple CPU shared device start address of
safety signal comparison parameter setting to use the speed monitoring
function. If the odd number is set, "Safety observation error (error code: 27)"
will occur.
The following 16 types of parameters can be registered as one-parameter
block and up to 32 blocks.
When the multiple parameter blocks are enabled for the same axis, the
monitoring process is executed with the lowest safety speed for the same
axis.
Set the axis No. which performs the speed monitor.
When "0" is set, the corresponding block is unused.
Set the detection time to detect that the motor speed during the speed
monitoring (while the speed monitoring is permitted) exceeds the safe rotation
speed.
Select the unit of the axis which performs the speed monitor. This setting should
be as the servo data setting.
Set the feedback pulse per motor rotation which is determined by machine
systems of the axis which performs the speed monitor. This setting should be
the same as the servo data setting value.
Set the machine travel value per motor rotation which is determined by machine
systems of the axis which performs the speed monitor. This setting should be
the same as the servo data setting value.
Set the number of pulses per rotation of an encoder used in the axis which
performs the speed monitor.
Set the number of pulses per rotation by an input of auxiliary pulse mechanically
connected to the axis which performs the speed monitor.
This cannot be set when the speed monitor axis uses a safety encoder and
safety communication function. The setting value is fixed (512[pulse]).
Set the travel value corresponding to one rotation by an input of auxiliary pulse
mechanically connected to the axis which performs the speed monitor.
This cannot be set when the speed monitor axis uses a safety encoder and
safety communication function. The setting value is fixed (the same value as
travel value per motor rotation).
Set the safety speed (upper limit speed while the speed monitor is permitted) of
the axis which performs the speed monitor as the speed converted to the
machine system.
Set the safety speed (upper limit speed while the speed monitor is permitted) of
the axis which performs the speed monitor as the motor speed.
Set the allowance value for the difference between the position command value
and the feedback position (position deviation value) while the speed monitor of
the axis which performs the speed monitor is permitted.
