User is defined as: integrator, operator, service technician,
maintenance technician.
Standards
Use of safe stop on terminal 37 requires that the user
satisfies all provisions for safety including relevant laws,
regulations and guidelines. The optional safe stop function
complies with the following standards.
•
IEC 60204-1: 2005 category 0 – uncontrolled stop
•
IEC 61508: 1998 SIL2
•
IEC 61800-5-2: 2007 – safe torque off (STO)
function
•
IEC 62061: 2005 SIL CL2
•
ISO 13849-1: 2006 Category 3 PL d
•
ISO 14118: 2000 (EN 1037) – prevention of
unexpected start-up
The information and instructions of the instruction manual
are not sufficient for a proper and safe use of the safe stop
functionality. The related information and instructions of
the relevant
Design Guide
must be followed.
Protective Measures
•
Qualified and skilled personnel are required for
installation and commissioning of safety
engineering systems
•
The unit must be installed in an IP54 cabinet or
in an equivalent environment. In special
applications, a higher IP degree is required
•
The cable between terminal 37 and the external
safety device must be short circuit protected
according to ISO 13849-2 table D.4
•
When external forces influence the motor axis (for
example, suspended loads), additional measures
are required (for example, a safety holding brake)
to eliminate potential hazards
Safe Stop Installation and Set-up
WARNING
SAFE STOP FUNCTION!
The safe stop function does NOT isolate AC line voltage to
the adjustable frequency drive or auxiliary circuits. Perform
work on electrical parts of the adjustable frequency drive
or the motor only after isolating the AC line voltage supply
and waiting the length of time specified in
.
Failure to isolate the AC line voltage supply from the unit
and waiting the time specified could result in death or
serious injury.
•
It is not recommended to stop the adjustable
frequency drive by using the Safe Torque Off
function. If a running adjustable frequency drive
is stopped by using the function, the unit trips
and stops by coasting. If unacceptable or
dangerous, use another stopping mode to stop
the adjustable frequency drive and machinery,
before using this function. Depending on the
application, a mechanical brake can be required.
•
For synchronous and permanent magnet motor
adjustable frequency drives, in a multiple IGBT
power semiconductor failure: In spite of the
activation of the Safe Torque Off function, the
system can produce an alignment torque which
maximally rotates the motor shaft by 180/p
degrees. p denotes the pole pair number.
•
This function is suitable for performing
mechanical work on the system or affected area
of a machine only. It does not provide electrical
safety. Do not use this function as a control for
starting and/or stopping the adjustable frequency
drive.
Follow these steps to perform a safe installation of the
adjustable frequency drive:
1.
Remove the jumper wire between control
terminals 37 and 12 or 13. Cutting or breaking
the jumper is not sufficient to avoid short-
circuiting. (See jumper on
.)
2.
Connect an external Safety monitoring relay via a
NO safety function to terminal 37 (safe stop) and
either terminal 12 or 13 (24 V DC). Follow the
instructions for the safety device. The Safety
monitoring relay must comply with Category
3 /PL “d” (ISO 13849-1) or SIL 2 (EN 62061).
