Introduction to the manual 25
hi-Z state
In digital outputs, the signal is neither driven to a logical high nor low
level. It is “floating”.
HTL
High-threshold logic
IGBT
Insulated gate bipolar transistor
Internal fault
A fault which is detected by FSO module’s internal diagnostics.
When an internal fault is detected, the FSO goes into fail-safe mode,
activates drive STO, and creates a fault to the drive.
I/O
Input/output
LSB
Least significant byte
MAC address
Media access control address. A unique identifier of a network node in
an communication network.
Mission time
T
m
. The period of time covering the intended use of a safety
function/device.
After the mission time the safety device(s) must be replaced. Note that
any T
m
values given cannot be regarded as a guarantee or warranty.
(EN ISO 13849-1).
MSB
Most significant byte
modoff
No modulation (the control of inverter IGBTs is off)
Warning:
‘No modulation’ is
not
a safe state. To achieve a safe state,
the STO function must be activated.
MTTF
D
Mean time to dangerous failure: (The total number of life units) / (the
number of dangerous, undetected failures) during a particular
measurement interval under stated conditions (EN ISO 13849-1)
N/A
Not applicable
NC
Normally closed. Break contact. Normally closed contacts disconnect
the circuit when the relay is energized; the circuit is connected when the
relay is de-energized.
NO
Normally open. Make contact. Normally open contacts connect the
circuit when the relay is energized; the circuit is disconnected when the
relay is de-energized.
OEM
Original equipment manufacturer
PCB
Printed circuit board
PELV
Protected extra-low voltage (IEC 60364-4-41)
PFD
avg
Average probability of dangerous failure on demand (IEC 61508)
PFH
Average frequency of dangerous failures per hour (IEC 61508)
PL
Performance level (a-e) (EN ISO 13849-1)
PLC
Programmable logic controller
POUS
Prevention of unexpected start-up
Power drive
systems (Safety
related), PDS(SR)
Adjustable speed electrical power drive system suitable for use in
safety-related applications
