Connectors X51, X52, X53
# Name Description
X51 STO OUT I
nverter modules: STO signal forwarding
output to next inverter module (if present).
X52 STO IN I
nverter modules: STO signals from BCU
control unit
X53 24V OUT 24 V DC output (for BCU control unit)
Note: The Safe torque off (STO) safety function is only
implemented in inverter units. Therefore, the STO function can
not be used in supply and brake units. In supply and brake
units, de-energizing any connection of STO IN (X52) connector
stops the drive. Note that this stop in supply or brake module is
not safety related and must not be used in safety function
purposes.
