ower supply of the STO function– on page 316.
STO A input
X2:3, X2:4
First channel of safe DC link disconnectio
n. This input operates the DC link + switch.
Technical data see ZIn
puts STO function– on page 316.
STO B input
X2:5, X2:6
Second channel of safe DC link disconnectio
n. This input operates the DC link - switch.
Technical data see ZIn
puts STO function– on page 316.
Ready-to-operate
output
X2:7, X2:8
The DC link capacitors are charged via resis
tors after switching on the DC link switch. Af-
ter that the loading resistors are bridged. Now it is possible to draw power from the DC
link by the d
ecentralized drive solutions BM2500. This state is shown by the ready-to-op-
erate output ((X2:7 X2:8 closed).
NOTICE!
The decentralized drive solutions BM2500 conne
cted to the DC link of the BM5030
must not be enabled to state „operation enabled“ before the ready-to-operate output
of the BM5030 is active, otherwise a damage of the device is possible.
Error output:
X2:9, X2:10
The error output is active (X2:9 X2:10 open) as long as the DC link STO function is
in er
ror state.
The error state is triggered by following incidents:
m STO error
m Over
temperature heat sink
m Fa
ult of heat sink temperature sensor
STO error:
m At
least on DC link switch is closed if the state of the STO inputs changes to „high“.
