1.4 General functional description
The encoTRive drive systems MP-
060…200-PN are optionally available with integrated safety tech-
nology, which safely switches off the motor torque after activation via a safe digital input and an op-
tional time duration.
● The two functions STO (Safe Torque Off) and SS1 (Safe Stop 1) comply with the standard
EN 61800-5-
2 “Adjustable speed electrical power drive systems - Part 5-2: Safety requirements -
Functional Safety”
● The safety requirement level corresponds to SIL CL2 in accordance with EN 62061 “Safety of
machinery - Functional safety of safety-related electrical, electronic and programmable electronic
control systems” and PL d, Cat. 3 in accordance with EN ISO13849-1 “Safety of machinery - Safe-
ty-related parts of control systems -
Part 1: General principles for design”.
The different configuration options are defined according to customer requirement and set in the facto-
ry.
The different selection options are:
● STO or SS1
● the desired SS1 time (e.g. 500 ms or 1000 ms)
● with or without short-circuit monitoring
The selection of the safety-oriented parameters occurs during the order process and is clearly as-
signed to a device variant. The selected parameters appear in the product data sheet, as well as in the
order papers for the respective variant and must be checked for correctness by the user when order-
ing.
As for drives without safety function, all drive functions are controlled
via the standardized non-
safety-oriented PROFINET interface
