‑11‑
General Safety Instructions
●Dynamic braking is common in rotating mechanical structures. For example, when
a motor has stopped running, it keeps rotating due to the inertia of its load. In this
case, this motor is in the regenerative state and short‑circuit current passes
through the dynamic brake. If this situation continues, the drive, and even the
motor, may be burned.
Safety Label
For safe equipment operation and maintenance, comply with the safety labels on the
equipment. Do not damage or remove the safety labels. See the following table for

●High attention is required for electrical installation and at the system design to
avoid hazards either in normal operation or in the event of equipment
malfunction.
●System design, installation, commissioning and maintenance must be carried out
by personnel who have the necessary training and experience. They must read the
operating instruction and this safety information.

General

It is the responsibility of the machine builder/OEM/system integrator to make sure
that the essential health and safety function requirements specified in the Machinery
Directive are met. Risk analysis and risk assessment is needed before using a product.
Make sure that adequate measures are taken to eliminate/reduce the relating risks
and components chosen must meet the safety requirements.
This section describes the information that needs to be noted before starting
operation. Read the following safety precautions, risk assessment information, and
limitations before starting operation.
Safety function: Use the safety function after properly understanding all of these
information. Incorrect use of safety functions or use of safety functions that are not
sufficient to meet the safety requirements of the site may result in personal injury.
Safety Precautions
Carefully read the following important precautions and observe them when using the
safety function.
●STO function is not intended as a replacement for the emergency stop function (E‑
stop). If only the STO function is triggered, with no extra measures taken, the
power supply cannot be cut off in emergencies and high‑current parts of the
motor and drive are still energized, incurring the risk of electric shock or other
risks result in electric energy. Therefore maintenance work on electrical parts of
the drive or motor can only be carried out after isolating the drive system from the
main supply.
●Depending on the standards and requirements for a particular application, it may
be possible to use STO as an integral part of an E‑stop system. However, its main
purpose is for use in a dedicated safety control arrangement whose purpose is to
prevent any hazard from occurring, without the use of an E‑stop.
●An E‑stop is often provided in a machine to allow for unexpected situations where
an operator sees a hazard and can take action to prevent an accident.
●The design requirement for an E‑stop differs from that of a safety interlock.
Generally, the E‑stop is required to be independent from any complex or
"intelligent" control. It may use purely electromechanical devices to either
disconnect the power or initiate a controlled rapid stop using other means such as
dynamic or regenerative braking.

Note
●The design of safety‑related systems requires specialist knowledge. To ensure that
a complete control system is safe, it is necessary for the whole system to be
designed according to recognized safety principles. The use of individual sub‑
systems such as drives with STO function, which are intended for safety‑related
applications, does not in itself ensure that the complete system is safe.
●The STO function can be used to stop the drive in emergency stop situations.
●In processes without personnel protection, it is recommended not to stop the
drive by using the STO function. If a drive running is stopped by using STO, the
drive performs a coast‑to‑stop. If this is not acceptable, the system should be
stopped using the correct mode instead of the STO function.
●This publication is a guide to the application of Inovance SV660 series safety
functions, and also on the design of safety‑related systems for machinery control.
●It is the responsibility of the designer of the end product or application to ensure
that it is safe and in compliance with the relevant regulations.
Risk Assessment
●When using the safety functions, perform risk assessment on the servo system in
advance. Make sure that the safety integrity level of the standards is met.
●The following residual risks can be present even when the safety functions
operate. Therefore, safety must always be given consideration during risk
assessment.
●If external forces (such as gravitational force with a vertical axis) are applied when
the safety functions are operating, the motor will rotate due to the action of these
external forces. Therefore, you must use a separate mechanical brake to secure
the motor.
Note
●In the case of failure of multiple IGBTs, regardless of whether the STO function is
enabled, the servo drive can generate an alignment torque. This torque can cause
the motor shaft to rotate within a range of up to 180÷p (for a synchronous
reluctance motor, the range is 180÷2p).
●p: Number of motor pole pairs.
To ensure safety, users should decide all the risk assessments and residual risks in the
entire machine equipment. A company and individual who constructed the safety
related system must take full responsibility for installation and commissioning of the
system. Additionally, when complying with a European machinery directive, the
related sub system must acquire safety standards certification, and the whole
equipment or system is subject to all risk assessments and safety class certification. It

is recommended that a Certification Body final safety certification of the system be
used.
The following shows residual risks concerning the safety function of this product.
Common residual risks
●At the shipment to end‑users, check the settings of safety related components
with programming tools and monitored/displayed contents on display and record
and save the setting data concerning the safety observation function and the
programming tools you used. Perform them using a check sheet, etc.
●The safety will not be ensured such as in assembling machine until installing,
wiring, and adjustment are completed properly. Install, wire, and adjust your
system referring to installation guide for each unit.
●Only qualified personnel are authorized to install, start‑up, repair or adjust the
machines in which these components are installed. Only trained engineers should
install and operate the equipment.
●Separate the wiring for safety observation function from other signal wiring.
●Protect the cables with appropriate ways (routing them in a cabinet, using a cable
guard, etc.).
●We recommend using a switch, relay, sensor, etc. which comply with safety
standards. When using a switch, relay, sensor, etc. which do not comply with
safety standards, perform a safety confirmation.
●Keep the required clearance/creepage distance depending on voltage you use.
●The time to a safety observation error depends on parameter settings.
Safe torque off (STO)
This function only cuts off the torque of the motor, and does not cut off the power
supply of the servo/inverter. Before servicing the servo/inverter, cut off the power
supply and ensure that the servo/inverter are not energized.
