Safety Function STO

Only
Qualified
Staff
Uncontrolled start is possible by improper installation of the sa-
fety function. This may cause death, serious bodily injuries or
substantial damage to property.
Therefore the safety function may only be installed and put into
operation by qualified personnel which are trained in safety tech -
nology.
Observe
Standards
The COMBIVERT F5 with safety function must not be started
until it is determined that the installation complies with 2006/42/
EC (machine directive) as well as the EMC directive (2004/108/
EC)(note EN60204).
The COMBIVERT F5 with safety function meets the requirements
of the Low-Voltage Directive 2006/95/EC. The harmonized stan -
dard of the series EN 61800-5-1 (VDE 0160) is used.
This is a product of limited availability in accordance with IEC
61800-3. This product may cause radio interference in residenti -
al areas. In this case the operator may need to take correspon -
ding measures.
With electronic protection devices the safety function is integrated in the drive control in order
to minimize or eliminate danger by malfunctions in machines. The integrated safety function
replace the complex installation of external safety components. The safety function can be
requested or released by an error.
Regular
checks
In order to ensure permanent security, the function must be che -
cked in regular intervals according to the results of the risk ana -
lysis.
Installation work or troubleshooting can be necessary in hazard areas, whereby protective
devices such as line- or motor contactors shall not be activated. The safety function STO can
be used there. Depending on the application the use of line or motor contactors can be void
by using STO.
In case of error or request, the power semiconductor of the drive module are switched off and
the drive is not supplied, which causes a rotation or torque (in case of a linear drive move -
ment or force). The unit can be safe switched off and/or remain if an error occurs.

Shock
Continue mains voltage with active STO function.
Compared to the disconnection by line contactors or motor contactors the integrated safety
function enables a simple integration of drives to functional groups of a system. Thereby safe
torque off can be limited to certain systems. A further advantage is that the recharge and
discharge time of the inverter DC link must not be considered. Thus the unit is faster again
ready for operation after an interruption.
Regular electromechanical equipment are liable to abrasion. Loss of these equipment occurs
by using the STO function and the maintenance costs are reduced.
Characteristic data for „Safe torque off“
• Power supply for the rotation direction of the motor is interrupted (free-wheeling motor)
