8 Maintenance and disposal
8.1 Maintenance
The drive amplifiers are maintenance free. Opening the drive amplifier voids the warranty.
8.2 Repairs
The drive amplifier may only be repaired by the manufacturer. Opening the drive amplifiers
voids the warranty and safety according to the specified standards is no longer ensured.
8.3 Disposal
In accordance with WEEE-2002/96/EC directive, we take back old equipment for proper
disposal as long as the transport costs are paid by the sender.

10 Instructions for STO safety function
The STO safety function (Safe Torque Off) is used for safe torque shutdown and to reliably
protect drives from restarting. The drive amplifier is fitted with a two-channel STO function as
standard in the basic model.
Advantages of the STO safety function:
− Intermediate circuit and main circuit can remain active
− No contact wear because only control voltages are switched on and off
− Less wiring required
− Single-channel or two-channel control possible
− SIL 2 or SIL 3 systems possible
The STO safety function equates to stop category 0 (uncontrolled stoppage) defined by EN
60204-1. The STO safety function of the servo drive can be triggered by external safety relays or
by an external safety control with safe outputs.
The circuit design has been tested and subsequently assessed by TÜV. According to that
assessment, the circuit design used for the "Safe Torque Off" safety function in the simco drive
series of drive amplifiers is suitable for meeting the requirements for SIL 3 in accordance with
EN 61508 and category 3 PLe in accordance with EN ISO 13849-1.
