Glossary
Safe Brake Control (SBC)
Safety function in accordance with EN
61800­5­2: "The SBC function supplies a safe
output signal or signals to drive an external
mechanical brake or brakes."
Safe Brake Test (SBT)
This safety function supplies a safe output sig­
nal for the cyclical test of the external holding
brake and motor brake. During the brake test,
the position is monitored by the safety function
SOS.
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 Position (SLP)
Safety function in accordance with EN
61800­5­2, prevents the motor shaft from ex­
ceeding the specified position 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."
