8 Safety Function
Precautions for Correct Use
• Set a multiple number of 128 to the setting value of SLP position upper limit - SLP posi-
tion upper limit 1 to SLP position upper limit 8 (66A2-01 hex to 08 hex). If you set other
number, the setting value is automatically corrected to the multiple number of 128 which
does not exceed the setting value. Example: When the setting value is between 256 and 383,
256 is automatically set to the setting value for the operation; when the setting value is
between 1 and 127, 0 is automatically set to the setting value for the operation.
• Set a multiple number of 128 to the setting value of SLP position lower limit - SLP position
lower limit 1 to SLP position lower limit 8 (66A4-01 hex to 08 hex). If you set other num-
ber, the setting value is automatically corrected to the lowest multiple number of 128 which
exceeds the setting value. Example: When the setting value is between 257 and 384, 384 is
automatically set to the setting value for the operation; when the setting value is between
-127 and -1, 0 is automatically set to the setting value for the operation.

Operation Procedure

This section describes how to use the SLP function.
1
Assign SLP function to safety PDO.
Assign instances from SLP command - SLP command 1 to SLP command 8 (66A0-01 hex to
08 hex) into safety PDO.
As for the details, refer to 8-1-4 Operating Procedure for Safety Function on page 8-8 in 8-1
Outline of Safety Functions on page 8-3.
2
Set safety origin position.
The settings vary in Safety Origin Position Determination Method (4F00-01 hex) for use. As
for the details, refer to 8-7-6 Setting of Safety Origin Position on page 8-89.
3
Set monitoring limits.
• Set upper limit values of safety monitoring position to instances of SLP position upper limit -
SLP position upper limit 1 to SLP position upper limit 8 (66A2-01 hex to 08 hex).
• Set lower limit values of safety monitoring position to instances of SLP position lower limit -
SLP position lower limit 1 to SLP position lower limit 8 (66A4-01 hex to 08 hex).
4
Activate SLP function.
SLP function starts monitoring of a safety position when SLP command assigned to safety PDO
is set to 0 (Activate SLP) from a safety controller.
