Description Assembly, Installation.
– Ensure correct protective earthing and shield connection.
– Prior to commissioning, ensure that the resulting movements of the connec­
ted actuators cannot endanger anyone.
– During commissioning: Systematically check all control functions and the
communication and signal interface between controller and drive regulator.
– The product is equipped with intermediate circuit capacitors, which store
dangerous voltage for up to 5 minutes after the power supply is switched off.
Before working on the product, switch off the power supply via the main
switch and secure it against being switched on again unintentionally. Before
touching the power connections, wait at least 5 minutes.
– Take into consideration the legal regulations for the respective destination.
– Keep the documentation somewhere safe throughout the entire product life­
cycle.
In the event of damage caused by unauthorised manipulation or any form of use
other than that intended, the warranty is invalidated, and the manufacturer is not
liable for damages.
In the event of damage caused by using unauthorised software or firmware with
the device, the warranty is invalidated, and the manufacturer is not liable for dam­
ages.
Safety instructions for the safety sub-functions
It is only possible to determine whether the product is suitable for specific applic­
ations by also assessing further components of the subsystem.
Analyse and validate safety function of the entire system.
The safety functions are to be checked at adequate intervals for proper function­
ing. Selecting the type of test and time intervals within the stated time period is
the responsibility of the operator. The check is to be conducted such that flawless
functioning of the safety device can be verified in interaction with all components.
Time period for cyclical test
è 15.1 Technical data, safety equipment.
Prior to initial commissioning, wire the control inputs of the safety sub­functions
STO and SBC. The safety sub­functions STO and SBC are available on the CMMT­
AS on delivery without the need for any additional parameterisation.
2.2 Intended use
The servo drive CMMT­AS is intended for supply and control of AC servo motors.
The integrated electronics permit regulation of torque (current), rotational speed
and position.
Use exclusively:
–
In perfect technical condition
– In original condition without unauthorised modifications; only the extensions
described in the documentation supplied with the product are permitted
– Within the limits of the product defined by the technical data
è 15 Technical data
– In an industrial environment
The safety functions might fail, and malfunctions might occur if you do not comply
with the parameters and conditions required for the surroundings and connec­
tions.
The CMMT­AS­...­S1 supports the following safety sub­functions in accordance
with EN 61800­5­2:
–
Safe torque off (STO)
– Safe brake control (SBC)
– Safe stop 1 (SS1), achievable with suitable safety relay unit and appropriate
wiring of the servo drive
The safety sub­function STO is intended to disconnect the torque of the connec­
ted motor, thereby preventing an unexpected restart of the motor.
The safety sub­function SBC is intended to safely hold the motor and axis in posi­
tion at standstill.
The safety sub­function SS1 is intended for performing a rapid stop with sub­
sequent torque switch­off.
2.2.1 Application areas
The device is intended for use in an industrial environment. Outside of industrial
environments, measures may need to be implemented for radio interference sup­
pression, e.g. in commercial and mixed­residential areas.
The device is intended to be installed in a control cabinet. The minimum degree of
protection required for the control cabinet is IP54.
The device can be operated in TN, TT and IT systems if certain requirements are
met.
Information on allowed and prohibited electrical network types and necessary
measures for use in IT networks
è Description Assembly, Installation.
Safety sub­functions may only be used for applications for which the stated safety
reference values are sufficient
è 15.1 Technical data, safety equipment.
2.2.2 Permissible components
The logic supply must meet the requirements of EN 60204­1 (protective extra­low
voltage, PELV).
If holding brakes and clamping units without certification are used, the suitability
for the related safety­oriented application must be determined through a risk
assessment.
The motors must fulfil the requirements of EN 61800­5­2 appendix D.3.5 and
D.3.6 and of EN 60204­1. Motors approved or specified by Festo for the CMMT­AS
fulfil the requirements.
The motor cables and brake lines must fulfil the requirements of EN 61800­5­2
appendix D.3.1 and of EN 60204­1. Motor cables and brake lines approved by
Festo for the CMMT­AS fulfil the requirements.
2.3 Foreseeable misuse
Foreseeable misuse, general
– Use outside the limits of the product defined in the technical data.
– Cross­wiring of the I/O signals of more than 10 servo drives CMMT­AS.
– Use in IT networks without insulation monitors for detection of earth faults.
If the device is operated in IT networks, the potential conditions will change in
the event of a fault (earth fault on the feeding mains supply). As a result, the
rated voltage of 300 V to PE – which has important implications for the design
of insulation and network disconnection – will be exceeded. This error must
be detected.
– Use of a diagnostic output for connection of a safety function.
The diagnostic outputs STA and SBA are not part of the safety circuit. The dia­
gnostic outputs are used to improve diagnostic coverage of the related safety
sub­function. The diagnostic outputs may only be used in combination with
the related safe control signals (AND operation) plus a reliable time monitor­
ing function in the safety relay unit for the purpose of switching additional
safety­critical functions.
Foreseeable misuse of the safety sub-function STO
– Use of the STO function without external measures for drive axis influenced
by external torques.
If external torques influence the drive axis, use of the safety sub­function STO
on its own is not suitable for stopping the axis safely. Additional measures
are required to prevent dangerous movements of the drive axis, such as use
of a mechanical brake in combination with the safety sub­function SBC.
– Disconnection of the motor from the power supply.
The safety sub­function STO does not disconnect the drive from the power
supply as defined by electrical safety.
Foreseeable misuse of the safety sub-function SBC
– Use of an unsuitable holding brake or clamping unit, also in view of:
–
Holding or brake torque and emergency brake characteristics, if required.
– Frequency of actuation
– Use of an unsuitable logic voltage supply
2.4 Training of qualified personnel
The product may be installed and placed in operation only by a qualified electro
