WARNING!
The drive is supplied from the factory with the ISO 13849-1 safety circuit enabled. The drive is not operational until +24V
is present at terminals 4 and 6. For the proper safety connections, refer to the “Connection of Two Safety Circuits with
External +24V Supply” diagram. Under certain applications when safety connections are not required the drive may be
operated with the safety circuit disabled. The diagram below illustrates how to bypass the safety circuit.

*1 – This voltage must under no circumstances be used to supply the ISO 13849-1 Safety circuits (terminals 3 to 6). This voltage is intended only for use
in bypassing (disabling) the ISO 13849-1 circuits should they not be required.
*2 – A Separate +24VDC supply providing reinforced isolation (SELV or PELV), must be supplied to operate these inputs. This supply should not be floating
but should be referenced within 20V peak of PE at the drive.
*3 – Unsnubbed inductive loads must NOT be used on the 24VDC safety circuit wiring.
PositionServo drives with the following “S” designation in the model number have been fitted with the
optional ISO 13849-1 Safe Torque Off function.
Drive Model Number : E94 P 020 S 1 N E S
The last “S” denotes ISO 13849-1
option fitted to drive at manufacturer.
This option can only be fitted at the factory at the time of unit manufacturer.
This option provides additional methods (Inputs) to disable the drive output so that the drive cannot cause
torque to be generated in the motor. This safety function is often referred to as the “Safe Torque Off”
function and meets the requirements of the following standard: ISO 13849-1 Safety of Machinery, Safety-
related Parts of Control Systems, Category (Cat.) 3, Performance Level (PL) d and Safety Integrity Level (SIL)
2, per EN 61800-5-2 2007.
WARNING!
It is required that all information contained within this ISO 13849-1 standard be observed
when implementing any part of this safety circuit functionality with the PositionServo drive.
