IEC 61800-5-1
Adjustable speed electrical power drive systems.
Part 5-1: Safety requirements - Electrical, thermal
and energy requirements. German version EN
61800-5-1.
PELV
Safe protective extra-low voltage (earthed).
Power-off function
The power-off function (short: Power-Off) is used
for a targeted reaction in the event of a mains
voltage failure (e.g. stopping the drive). The en-
ergy stored in the drivetrain is utilised for this pur-
pose.
RS485
RS-485 is an industry standard according to
EIA-485 for a physical interface for asynchronous,
serial data transmission.
Safety over EtherCAT®
Safety over EtherCAT® is a registered trademark
and patented technology, licensed by Beckhoff
Automation GmbH, Germany.
SBC
Safe Brake Control.
SDLC
Safe Door Lock Control
SELV
Safe protective extra-low voltage (unearthed;
<60V).
SinCos
Incremental encoder with sinusoidal signals.
SLA
Safely limited acceleration
SLS
Safely limited speed
ma_dr_s6-cu-p-inst-20156056_en
SMS
Safe maximum speed
SS1-r
Safe Stop 1 ramp monitored (with deceleration
ramp monitoring; STO (Safe torque off) is as-
sumed after reaching the idle position.
SS1-t
Safe Stop 1 time controlledSTO (Safe torque off)
is assumed after the deceleration time has
elapsed.
SSI
Synchronous serial interface for encoder.
SSM
Safe speed monitor
STO
Safe torque off (STO).
