900-200-100 25/57
2. Specifications
2.1. Overview
The Safety Module is an Option Module that is connected to a Σ-V Series, Large-Capacity Σ-V Series, or Σ-7
Series SERVOPACK. By using the Hard Wire BaseBlock function of the SERVOPACK, the following four safety
functions, which are defined in functional safety standards, can be achieved.
Function
Remarks
Safe BaseBlock Function
(SBB function)
This is a safety function that is equivalent to the Safe Torque Off
function defined in IEC 61800-5-2.
Safe BaseBlock with Delay Function
(SBB-D function)
This is a safety function that is equivalent to the Safe Stop 1
function defined in IEC 61800-5-2.
Safe Position Monitor with Delay Function
(SPM-D function)
This is a safety function that is equivalent to the Safe Stop 2
function defined in IEC 61800-5-2.
Safely Limited Speed with Delay Function
(SLS-D function)
This is a safety function that is equivalent to the Safely-Limited
Speed function defined in IEC 61800-5-2.
When the Safety Module is attached to the SGD7W, the Safety Module operates for Axis A only. Axis B is not related
to the Safety Module.
When using the combination of the ∑-7S SERVOPACK with 400 V-Input Power model and the Safety Module(SGDV-
OSA01A000FT900), in addition to the above functions, Hardware BaseBlock Function (HWBB) of SERVOPACK CN8 is
available.
Function
Remarks
Hardwire BaseBlock Function
(With HWBB input of SERVOPACK CN8)
This is a safety function that is equivalent to the Safe Torque Off
function defined in IEC 61800-5-2.
When using the combination of the ∑-7W SERVOPACK with 400 V-Input Power model and the Safety
Module(SGDV-OSA01A000FT900), in addition to the above functions, Hardware BaseBlock Function (HWBB) of
SERVOPACK CN8A(Axis A) is available.
Function
Remarks
Hardwire BaseBlock Function
(With HWBB input of SERVOPACK CN8A)
This is a safety function that is equivalent to the Safe Torque Off
function defined in IEC 61800-5-2.
In the other hands, Hardware BaseBlock Function (HWBB) of SERVOPACK CN8B(Axis B) is available regardless of the
Safety Module models.
