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.
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
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
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
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.
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.
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.
