Glossary
Safe Direction (SDI)
Safety function in accordance with EN
61800­5­2: "The SDI function prevents the mo­
tor shaft from moving in an unintended direc­
tion."
Safe Operating Stop (SOS)
Safety function in accordance with EN
61800­5­2: "The SOS function prevents the
motor from deviating from the stop position by
more than a defined amount. The PDS(SR)
(electrical power drive system) supplies power
to the motor that enables it to withstand the en­
gagement of external forces."
Safe Speed Range (SSR)
Safety function in accordance with EN
61800­5­2: "The SSR function holds the motor
speed within defined limit values."
Safe Stop 1 (SS1)
Safety function in accordance with EN
61800­5­2: "The PDS(SR) performs one of
these functions: a) Either initiates and controls
the length of the motor delay within defined lim­
its and initiates the STO function (see 4.2.2.2)
if the motor speed falls below a defined limit
value, or b) Initiates and monitors the length of
the motor delay within defined limits and initi­
ates the STO function if the motor speed drops
below a defined limit value, or c) Initiates the
motor delay and then initiates the STO function
after an application­specific time delay."
Safe Stop 2 (SS2)
Safety function in accordance with EN
61800­5­2: "The PDS(SR) performs one of
these functions: a) Either initiates and controls
the length of the motor delay within defined lim­
its and initiates the SOS function (see 4.2.3.1)
if the motor speed falls below a defined limit
value, or b) Initiates and monitors the length of
the motor delay within defined limits and initi­
ates the SOS function if the motor speed drops
below a defined limit value, or c) Initiates the
motor delay and then initiates the SOS function
after an application­specific time delay."
Safe Torque Off (STO)
Stop function in accordance with EN
61800­5­2: "No power that can cause a rota­
tion (or in the case of a linear motor, a move­
ment) is supplied to the motor. The PDS(SR)
(electrical power drive system) does not supply
any power to the motor that can generate
torque (or in the case of a linear motor, force)."
Safely Limited Increment (SLI)
Safety function in accordance with EN
61800­5­2, prevents the motor shaft from ex­
ceeding the specified increment limit.
Safely Limited Speed (SLS)
Safety function in accordance with EN
61800­5­2: "The SLS function prevents the mo­
tor from exceeding the specified speed limit."
