7 Commissioning
Once the power supply has been connected to the frequency inverter, it will be operational within a few
moments. In this state, the frequency inverter can be set to the requirements of the application, i.e. it can be
configured. A detailed and complete description of each parameter is contained in BU 0500 GB.
ATTENTION
DANGER TO LIFE!
The frequency inverter is not equipped with a line main switch and is therefore always live when
connected to the power supply. Live voltages may therefore be connected to a connected motor
at standstill.
ATTENTION
The connected motor may only be started after the parameters specific to the application in
question have been set by qualified personnel.
Special care is necessary during commissioning until the correct behaviour of the safety
functions has been demonstrated by means of validation. If necessary, possible hazards during
commissioning must be avoided by organisational means.
During commissioning, the following steps with regard to functional safety must be carried out:
STO:

One safety output of the safety switching device is connected to the safe pulse block (Terminal 89
(24V_SH) and terminal 88 (GND_SH).
According to the required safety category, if necessary, a wiring fault (short-circuit between any arbitrary
wires) must be able to be ruled out.
It is recommended that a two-conductor shielded cable is used for the safe shut-down method (See also
Section 2.3.5 "Ruling out wiring faults").
The shield must be applied on both sides!

The typical reaction time can be reduced by the additional use of a digital input.
With the Safe Pulse Block, the diagnostic path "Status at the input terminals", which is in the form of
the digital input parallel to the safe pulse block, can be used. For this, the digital input with the function
"Block voltage" is used.
It is recommended that a separate shielded cable is used for each safe shut-down method and for the
digital inputs used for functional safety. (see also Section 2.3.5 "Ruling out wiring faults"). The shield
must be applied on both sides!

The On/Off switching delay of the digital input must not be used: P475 [-0x] = 0 s!

According to the application, disabling of the safety function may cause a hazard, so that a monitored start
is necessary. In this case, the automatic start may not be used, P428 = "Off" [0].
