Safe torque off connection (XSTO)
Input voltage range: -3…30 V DC
Logic levels: “0” < 5 V, “1” > 17 V.
Note: For the unit to start, both connections must be “1”. This applies
to all control units (including drive, inverter, supply, brake, DC/DC
converter etc. control units), but true Safe torque off functionality is
only achieved through the XSTO connector of the drive/inverter
control unit.
EMC (immunity) according to IEC 61326-3-1
Connector pitch 5 mm, wire size 2.5 mm 2 Safe torque off output (XSTO OUT)
To STO connector of inverter module.
Connector: RJ-45 Control panel connection (X13)
Cable length < 3 m
Connector: RJ-45 Ethernet connection (XETH)
This connection is not supported by the firmware.
Memory card type: SDHC SDHC memory card slot (SD CARD)
Maximum memory size: 4 GB
The terminals of the control unit fulfill the Protective Extra Low Voltage (PELV) requirements. The PELV re-
quirements of a relay output are not fulfilled if a voltage higher than 48 V is connected to the relay output.
