Standby supply board
option
The standby supply board option provides the possibility of
keeping the communication system up and running without
having the 3-phase mains connected. One advantage is that
the system can be set up without mains power. The option
will also give backup for communication failure if main
power is lost.
The standby supply board option is supplied with external
±10% 24 V
DC
protected by a 2 A slow acting fuse, from a
double isolated transformer. The terminals X1:1, X1:2 (on
size B, C and E to F) are voltage polarity independent.
The terminals A- and B+ (on size D) are voltage polarity
dependent.

Safe Stop option
To realize a Safe Stop configuration in accordance with Safe
Torque Off (STO) EN-IEC 62061:2005 SIL 3 & EN-ISO
13849-1:2006, the following three parts need to be attended
to:
1. Inhibit trigger signals with safety relay K1 (via Safe Stop
option board).
2. Enable input and control of AC drive (via normal I/O
control signals of AC drive).
3. Power conductor stage (checking status and feedback of
driver circuits and IGBT’s).
To enable the AC drive to operate and run the motor, the
following signals should be active:
•
"Inhibit" input, terminals 1 (DC+) and 2 (DC-) on the
Safe Stop option board should be made active by con-
necting 24 V
DC
to secure the supply voltage for the
driver circuits of the power conductors via safety relay
K1. See also Fig. 107.
•
High signal on the digital input, e.g. terminal 10 in Fig.
107, which is set to "Enable". For setting the digital
input please refer to section 10.5.2, page 132.
