1 Safety and requirements for product use
1.1 Safety
Caution
Short circuits can lead to sudden unloading of the intermediate circuit condens-
ers and energy development:
– when the module or cover plate is not mounted on the card slot [EXT]
– when cables are not mounted to the plugs [X6] and [X9]
– when connecting cables are disconnected when powered.
The product must be installed in a control cabinet. The product may only be used
if all safeguarding has been installed and is operational. Before maintenance,
repair and cleaning work and when there have been long service interruptions:
1. Switch off power to the electrical equipment via the mains switch and secure
it against being switched on again.
2. After switch-off, wait at least 1 minutes discharge time and check that power
is turned off before accessing the controller.
Caution
Danger of burns from hot surfaces
Dependent on the load, housing temperatures > 80 °C are possible in operation.
• Protect hot surfaces from contact in operation.
• Touch them only in a switched-off, cooled-off status.
Note
Danger from unexpected movement of the motor or axis
• Make sure that the movement does not endanger anyone.
• Perform a risk assessment in accordance with the EC Machinery Directive.
• Based on this risk assessment, design the safety system for the entire ma-
chine, taking into account all integrated components.

Intended use
The motor controller CMMS-ST-...-G2 is a digital positioning controller for stepper
motors for
– supply and activation of the motor
– regulation of speed (current), torque and position.
The motor controller supports the following safety function:
– "Safe torque off " (STO)
Category 3 / PL d in accordance with EN ISO 13849-1.
Use exclusively:
– in an excellent technical status
– in original status, without unauthorised modifications
– within the limits of the product defined through the technical data
– for the safety function within the specified service life of the switching elements
Section 9
– in an industrial environment
– as an installed device in a control cabinet.
Issue status of the specified standards
EN 60204-1:2006/A1:2009-02
EN 61800-2:1998-04
Foreseeable misuse of the safety function
– use outside or in a non-industrial area (residential area),
– use in applications where switching off can result in hazardous movements or
conditions.
English
Note
– The STO function is insufficient as the sole safety function for drives subject to
permanent torque or force (e. g. suspended loads).
– Bypassing of safety equipment is impermissible.
– Repairs to the motor controller are impermissible!
The STO (Safe Torque Off ) function does not provide protection against
electric shock, only against dangerous movements!
In applications with extremely high requirement rates, the service life of the
switching elements must be taken into account in the design (replacement interval
for the motor controller)
Attainable safety level in accordance with EN ISO 13849-1
The motor controller can be used in applications up to Cat. 3 / PL d in accordance
with EN ISO 13849-1. The overall achievable safety level depends on the other
components used to achieve the safety function.
1.2 Requirements for product use
For correct and safe use of the product:
• Comply with the connection and ambient conditions of the product and all con-
nected components specified in the technical data. Compliance with the limit
values and load limits permits operation of the product in compliance with the
relevant safety regulations.
• Observe the instructions and warnings in the documentation.
• For the safety function: If the safety function is demanded, protection against
automatic restart corresponding to the required category must be furnished,
e.g. via an external safety switching device.
Qualification of the specialists (requirements for the personnel)
The product may only be placed in operation by a qualified electrotechnician who
is familiar with:
– the installation and operation of electrical control systems,
– the applicable regulations for operating safety-engineered systems,
– the applicable regulations for accident protection and occupational safety, and
– the documentation for the product.
Diagnostic coverage (DC) for the safety function
Diagnostic coverage depends on the interconnection of the motor controller with
the control loop system as well as the implemented diagnostics measures.
If a potentially dangerous malfunction is recognised during the diagnostics, appro-
priate measures must be taken to maintain the safety level.
Note
Check whether a fault exclusion of cross circuits in the input circuit and connec-
tion wiring is possible in your application.
If necessary, use a safety switching device with cross-circuit detection.
Range of application and certifications
The motor controller with integrated STO safety function is a safety-related part of
the control systems. The motor controller carries the CE marking.
