The control sections of the IndraDrive Cs range can be equipped with the
optional modules "L3" [STO (Safe Torque Off)] or "L4" [STO (Safe Torque
Off) and SBC (Safe Brake Control)].
The mentioned optional modules equip IndraDrive Cs with integrated safety
technology which provides the user with safe torque off and, if using the
optional module "L4", additionally with the safe control of a brake.
The IndraDrive Mi systems with the distributed servo drive KSM02 and the
distributed drive controller KMS02 can be equipped with the optional module
"L3" [STO (Safe Torque Off)].
The optional module "L3" equips IndraDrive Mi with integrated safety
technology which provides the user with safe torque off.
The Cxx02 control sections of the IndraDrive M / IndraDrive C range can be
equipped with the optional module "L3" [STO (Safe Torque Off)].
The optional module "L3" equips IndraDrive M / IndraDrive C with integrated
safety technology which provides the user with safe torque off.
The Cxx02.5 control sections of the IndraDrive ML range can be equipped
with the optional module "L3" [STO (Safe Torque Off)].
The optional module "L3" equips IndraDrive ML with integrated safety
technology which provides the user with safe torque off.
