8DESCRIPTION OF THE SAFETY
MODULE (SAF-001)
This chapter describes the Safety Module (SAF-001), the meaning of the display and
operation elements and the type code applied to the module.
8.1 General
8.1.1 Safety Module SAF-001-000-xxx and SAF-001-001-000 with safety function STO
The Safety Module (SAF-001-000-xxx) is a pure hardware solution for realization of the
safe shutdown of the optocouplers in the driver stage of converters (the parameterization
via software is not possible).
The safety module (SAF-001-001-xxx) enables the safe shutdown of the optocouplers in
the driver of converters by means of the microcontroller. A software parameterizing is not
possible.
The modules SAF-001-000-xxx and SAF-001-001-000 only perform the safety function
„Safe Torque Off (STO)“ (according to EN
61800-5-2). With the safety function STO, the
drive is shut down by the safe pulse inhibitor.
Safe Torque Off (STO):
m With the safety function STO, the actuation of the power output module is safely
interrupted. Thus, the motor can no longer generate a rotary field. The motor coasts
down in an uncontrolled manner when this safety function is activated.
m The safety function STO corresponds to Stop Category 0 of EN 60204-1.
8.1.2 Safety Module SAF-001-001-001 with safety function SS1 (time controlled)
After expiry of a specified time the safety module (SAF-001-001-001) allows a safe
switching off of the optocouplers in the driver stage of converters by means of
microcontrollers. A parameterization via the software is not possible.
The module SAF-001-001-001 carries out the safety function "Safe Stop 1 (SS1)" (safe
stop 1 with time control according to EN61800-5-2), exclusively. After the expiry of the
