Installation
Protective Measures
•
Safety engineering systems may only be installed
and commissioned by qualified and skilled
personnel
•
The unit must be installed in an IP54 cabinet or
3 3
in an equivalent environment
•
The cable between terminal 37 and the external
safety device must be short circuit protected
according to ISO 13849-2 table D.4
•
If any external forces influence the motor axis
(e.g. suspended loads), additional measures (e.g. a
safety holding brake) are required in order to
eliminate hazards.
Safe Stop Installation and Set-up
WARNING
SAFE STOP FUNCTION!
The safe stop function does NOT isolate AC line voltage to
the drive or auxiliary circuits. Perform work on electrical
parts of the drive or the motor only after isolating the AC
line voltage supply and waiting the length of time
specified under Safety in this manual. 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 drive by using
the Safe Torque Off function. If a running drive is
stopped by using the function, the unit will trip
and stop by coasting. If this is not acceptable,
e.g. causes danger, the drive and machinery must
be stopped using the appropriate stopping mode
before using this function. Depending on the
application, a mechanical brake may be required.
•
Concerning synchronous and permanent magnet
motor adjustable frequency drives in case of a
multiple IGBT power semiconductor failure: In
spite of the activation of the Safe torque off
function, the drive 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 drive system or affected
area of a machine only. It does not provide
electrical safety. This function should not be used
as a control for starting and/or stopping the
drive.
The following requirements have to be met to perform a
safe installation of the drive:
1. Remove the jumper wire between control
terminals 37 and 12 or 13. Cutting or breaking

Illustration 3.14 Jumper between Terminal 12/13 (24V) and 37
DET-759A
the jumper is not sufficient to avoid short-
circuiting. (See jumper on Illustration 3.14.)
Connect an external Safety monitoring relay via a
NO safety function (the instruction for the safety
device must be followed) to terminal 37 (safe
stop) and either terminal 12 or 13 (24V DC). The
safety monitoring relay must comply with
Category 3 (EN 954-1) / PL "d" (ISO 13849-1).
