- 98 -
13837 Safety machine position 4 for each axis (+ direction)
13838 Safety machine position 4 for each axis (- direction)
NOTE
When this parameter is set, the power must be
turned off before operation is continued.
[Input type] Parameter input
[Data type] Real axis
[Unit of data] mm, inch, degree (machine unit)
[Minimum unit of data] Depend on the increment system of the applied axis
[Valid data range] 9 digits of minimum unit of data (Refer to standard parameter setting
table(A). But in case that CMR≥1, data range becomes 1/CMR of 9
digits of minimum unit of data.)
(When the increment system is IS-B and CMR=1, -999999.999 to
+999999.999)
(When the increment system is IS-B and CMR=2, -499999.999 to
+499999.999)
NOTE
Whether to specify this parameter by using a
diameter value or radius value depends on whether
the corresponding axis is based on diameter
specification or radius specification.
Set a safe machine position for each axis.
CNC and Servo always check the machine position on each axis in
Dual Check Safety function.
If the machine position is out of the safety machine range even on one
axis, Monitoring Result signal (RSVx) corresponding to that axis is
set to “0”. Moreover if Safety Check request signal (*VLDVx) is set
to “0”, an alarm SV0477 or SV0495 is generated for the
corresponding axis.
Up to 4 safety machine position can be specified. Safety machine
position is selected by Safety Speed / Safety Position Selection signal
(SVAx/SVBx). As for the detail of Safety Speed / Safety Position
Selection signal, refer to the description about Safety Speed / Safety
Position Selection signal.
CAUTION
The safety machine position checks are made on
the basis of the machine position to the detection
unit. Accordingly, a calculation error may occur.
