WARNING
Improper installation of the safety circuitry may result in uncontrolled starting of the
drive. This may cause death, serious injuries and significant material damage.
Safety functions may only be installed and commissioned by skilled personnel.
The STO function is not suitable for emergency stop as per EN 60204. An emergency
stop can be realized by installing a mains contactor.
An emergency stop according to EN 60204 must be functioning in all operation modes
of the frequency inverter. Resetting of an emergency stop must not result in
uncontrolled starting of the drive.
The drive is started again when the function STO is no longer required. In order to
comply with EN 60204, ensure by taking external measures that the drive does not
start without prior confirmation.
Without a mechanical brake, the drive will not stop immediately but coast to a
standstill. If this may result in personal or material damage, additional safety
measures must be taken.
If persons may be endangered after disconnection of the motor power supply by
STO, access to the hazard areas must be prevented until the drive has stopped.
Check the safety function at regular intervals according to the results of your risk
analysis. Bonfiglioli Vectron MDS GmbH recommends that the check be performed
after one year, at the latest.
The STO function is fail-safe. However, on rare occasions, the occurrence of
component defects may cause jerking of the motor shaft (max. 180°/pole pair, e. g.
jerk by 90° with 4-pole motor, 180°/2). Check if this causes a dangerous movement
of the machine.
If the STO function is used, the special safety, installation and instructions on use
instructions shall be complied with.
The application manual "Safe Torque Off STO" must be complied with, particularly if
the safety function described there is used.
Warning! Dangerous voltage!
The safety function “Safe Torque Off” may only be used if mechanical work is to be
performed on the driven machines, not for work on live components.
After disconnection of an external DC 24 V power supply, the DC link of the frequency
inverter is still connected to mains supply.
Even if power supply to the motor is disconnected, and the motor is coasting to a
standstill or has already stopped, high voltages may still be present on the motor
terminals.
Before working (e. g. maintenance) on live parts, the plant must always be
disconnected from mains supply (main switch). This must be documented on the
plant.
When the function “Safe Torque Off” is triggered, the motor is not isolated from the
DC link of the frequency inverter. High voltage levels may be present at the motor.
Do not touch live terminals.
2.11 Safety Instructions on Function “Safe Torque Off” (STO)
The function „Safe Torque Off“ (STO) is a functional safety feature, i.e. it protects staff from damage,
provided that projecting, installation and operation are performed properly. This function does not
disconnect the plant from power supply.
In order to disconnect the plant from power supply (e.g. for maintenance work), an "Emergency Stop"
provision as per EN 60204 must be installed.

WARNING
The electrical installation must be carried out by qualified electricians according to the
general and regional safety and installation directives.
The documentation and device specification must be complied with during installation.
Before any assembly or connection work, discharge the frequency inverter. Verify safe
isolation from power supply.
When the frequency inverter is disconnected from power supply, the mains, DC-link
voltage and motor terminals may still be live for some time. Work on the device may
only be started once the DC link capacitors have discharged. The time to wait is at least
3 minutes in the case of sizes 1 through 7.
Do not connect inappropriate voltage sources. The nominal voltage of the frequency
inverter must correspond to the supply voltage.
The frequency inverter must be connected to ground potential.
Do not remove any covers of the frequency inverter while power supply is on.
CAUTION
IP20 ingress protection rating is only achieved with terminals plugged and properly
mounted covers.
7 Electrical installation
The connecting cables must be protected externally, considering the maximum voltage and current
values of the fuses. The mains fuses and cable cross-sections are to be selected according to
EN 602041 and DIN VDE 0298 Part 4 for the nominal operating point of the frequency inverter.
According to UL/CSA, the frequency inverter is suitable for operation at a supply network of a
maximum of 480 VAC which delivers a maximum symmetrical current of 5000 A (effective value) if
protected by fuses of class RK5. Only use copper cables with a temperature range of 60 / 75 °C.
The frequency inverters are to be grounded properly, i.e. large connection area and with good
conductivity. The leakage current of the frequency inverters may exceed AC 3.5 mA or DC 10 mA.
According to EN 61800-5-1 a permanent connection must be provided. The protective conductor
cross-section required for grounding the fixing plate must be selected according to the size of the unit.
In these applications, the cross-section must correspond to the recommended cross-section of the
wire.
Special connection variants are possible apart from the standard connection variant described in these
Operating Instructions:
Parallel connection (see "Application Manual – Parallel Connection")
DC supply (if you have any questions on this, contact BONFIGLIOLI Customer Service.)
Connection Conditions
The frequency inverter is suited for connection to the public or industrial supply mains according
to the technical data. If the transformer output of the supply mains is ≤ 500 kVA, a mains
commutation choke is only necessary for the frequency inverters identified in the technical data.
The other frequency inverters are suitable for connection without a mains commutating choke
with a relative mains impedance 1%.
Check, based on the specifications of EN 61000-3-2, if the devices can be connected to the public
supply means without taking additional measures. The frequency inverters ≤ 9.2 kW with
integrated EMC filter comply with the emission limits of the product standard EN 61800-3 up to a
motor cable length of 10 m, without additional measures being required. Increased requirements
in connection with the specific application of the frequency inverter are to be met by means of
optional components. Commutating chokes and EMC filters are optionally available for the series
of devices.

WARNING
Please note (according to EN61800-5-1): This product may cause direct current in the
protective earth conductor. Where residual current devices (RCD) or residual current
monitors (RCM) are used as a protection against direct or indirect contact, only RCDs /
RCMs of Type B are permissible on the power supply side of this product.
Operation on an unearthed mains (IT mains) is admissible after disconnection of the Y capacitors
in the interior of the device. For disconnection of the Y capacitors, please contact
BONFIGLIOLI.
Interference-free operation with residual current device is guaranteed at a tripping current 30
mA if the following points are observed:
One-phase power supply (L1/N): Pulse current and alternating current sensitive residual
current devices (Type A to EN 61800-5-1)
Two-phase power supply (L1/L2) or Three-phase power supply (L1/L2/L3):
All-current sensitive residual current devices (Type B to EN 61800-5-1)
Use EMC filters with reduced leakage current or, if possible, do not use EMC filters at all.
The length of the shielded motor cable is ≤ 10 m and there are no additional capacitive
components between the mains or motor cables and PE.
The fuses to be used are to be selected depending on the specific application. The safety
recommendations in the Technical Data are valid for continuous operation without overload.
The frequency inverters are designed according to the requirements and limit values of product norm
EN 61800-3 with an interference immunity factor (EMI) for operation in industrial applications.
Electromagnetic interference is to be avoided by expert installation and observation of the specific
product information.
Measures
Install the frequency inverters and commutating chokes on a metal mounting panel. Ideally, the
mounting panel should be galvanized, not painted.
Provide proper equipotential bonding within the system or plant. Plant components such as
electrical cabinets, control panels, machine frames must be connected by means of PE cables, i.e.
sufficient area and with good conductivity.
The shield of the control cables is to be connected to ground potential properly, i.e. with good
conductivity, on both sides (shield clamp). Mount shield clamps for cable shields close to the unit.
Connect the frequency inverter, the commutating choke, external filters and other components to
an earthing point via short cables.
Excessive cable length and loosely suspended cabling must be avoided.
Contactors, relays and solenoids in the electrical cabinet are to be provided with suitable
interference suppression components.

A
Mains connection
The length of the mains supply cable is not limited. However, it
must be installed separate from the control, data and motor
cables.
B
DC-link connection
The frequency inverters are to be connected to the same mains
potential or a common direct voltage source. Cables longer than
300 mm are to be shielded. The shield must be connected to the
mounting panel on both sides.
C
Control connection
Keep control and signal cables physically separate from the
power cables. Analog signal lines are to be connected to the
shield potential on one side. Install sensor cables separate from
motor cables.
D
Motor and braking resistor
The shield of the motor cable is to be connected to ground
potential properly on both sides. On the motor side use a metal
compression gland. On the frequency inverter side an
appropriate shield clamp is to be used. The signal cable used for
monitoring the motor temperature must be kept separate from
the motor cable. Connect the shield of this line on both sides. If
a braking resistor is used, the connection cable must also be
shielded, and the shield is to be connected to earth potential on
both sides.
Relay
The relay enables using high-energy signals.
Line choke
Line chokes reduce mains harmonics and reactive power. In addition, a longer service life of the
frequency inverter is possible. When using a line choke, note that line chokes may reduce the
maximum output voltage of the frequency inverter.
The line choke must be installed between the mains connection and the input filter.
Input filter
Input filters reduce grid-bound, high-frequency radio interference voltage.
Install the input filter on the mains side upstream of the frequency inverter.
CAUTION
The frequency inverters meet the requirements of the low-voltage directive
2006/95/EC and the requirements of the EMC directive 2004/108/EC. The EMC
product standard EN 61800-3 relates to the drive system. The documentation
provides information on how the applicable standards can be complied if the
frequency inverter is a component of the drive system. The declaration of conformity
is to be issued by the supplier of the drive system.

7.4 Connection of Unit
7.4.1 Dimensioning of conductor cross-section
The connecting cables must be protected externally, considering the maximum voltage and maximum
current values of the fuses. The line fuses and cable cross-sections must be dimensioned according to
EN 602041 and DIN VDE 0298 Part 4 for the nominal operating point of the frequency inverter.
The cable dimensions should be selected according to the current load and voltage drop to be
expected. Select the cable cross-section of the cables such that the voltage drop is as small as
possible. If the voltage drop is too great, the motor will not reach its full torque. Also comply with any
additional national and application-specific regulations and the separate UL instructions. For typical
mains fuses, refer to chapter 5 "Technical data".
According to EN61800-5-1, the cross-sections of the PE conductor shall be dimensioned as follows:
The following tables provide an overview of typical cable cross-sections (copper cable with PVC
insulation, 30 °C ambient temperature, continuous mains current max. 100% rated input current,
installation variant C). Actual mains cable cross-section requirements may deviate from these values
depending on actual operating conditions.
The following tables provide an overview of typical cable cross-sections (copper cable with PVC

Motor cables can be much longer if sinus filters are used. By conversion in sinus-shaped currents,
high-frequency portions which might limit the cable length are filtered out. Also consider the voltage
drop across the cable length and the resulting voltage drop at the sinus filter. The voltage drop results
in an increase of the output current. Check that the frequency inverter can deliver the higher output
current. This must be considered in the projecting phase already.
If the motor cable length exceeds 300 m, please consult BONFIGLIOLI.
7.4.3.4 Group drive
In the case of a group drive (several motors at one frequency inverter), the total length shall be

The ACU frequency inverters can evaluate the thermal switch of motor. By default, terminal X210B.1
(S6IND) is configured as an input for this evaluation. Connect the thermal switch to the digital input
and the DC 24 V supply unit X210A.1. For parameterization, refer to Sections 14.6 “Motor
temperature” and 16.4.5 “Thermocontact”.
The control hardware and the software of the frequency inverter are freely configurable to a great
extent. Certain functions can be assigned to the control terminals, and the internal logic of the
software modules can be freely selected.
Thanks to the modular design, the frequency inverter can be adapted to a great range of different
driving tasks.
The demands made of the control hardware and software are well known in the case of standard
driving tasks. This control terminal logic and internal function assignments of the software modules
are available in standard configurations. These assignments can be selected via Configuration 30.
The configurations are described in the following section.
The ACU devices of the ACTIVE Cube series feature the integrated STO function (“Safe
Torque Off”). If this function is not required, the “Controller release” signal must be
connected to inputs S1IND/STOA and S7IND/STOB.
Inputs S1IND/STOA and S7IND/STOB are connected in series.
WARNING
The digital inputs S1IND/STOA and S2IND are driven by the same signal, safe
disconnection of energy supply to the motor as per the STO safety function (“Safe Torque OFF”) is not guaranteed.

Control methods 2xx can be used with HTL encoders (with or without reference pulse)
at basic device or an extension module.
In order to use control methods 2xx with TTL encoders, an extension module is
required.
An extension module EM-RES for evaluation of resolver signals is required for operation
of a synchronous machine (control method 5xx).
An extension module EM-ABS for signal evaluation is required for operation with
absolute encoders (Hiperface, EnDat2.1, SSI).
