Analog outputs AO1 and AO2 (XAO)
0…20 mA, R
load
< 500 ohm
Frequency range: 0…300 Hz (ZCU-1x), 0…500 Hz (BCU-x2)
Resolution: 11 bit + sign bit
Inaccuracy: 2% of full scale range
Connector pitch 5 mm, wire size 2.5 mm 2 XD2D connector
Physical layer: RS-485
Transmission rate: 8 Mbit/s
Cable type: Shielded twisted-pair cable with a twisted pair for data
and a wire or another pair for signal ground (nominal impedance
100 … 165 ohm, for example Belden 9842)
Maximum length of link: 50 m (164 ft)
Termination by jumper (ZCU-1x) or switch (BCU-x2)
Connector pitch 5 mm, wire size 2.5 mm

RS-485 connection (X485) (BCU-x2 only)
Physical layer: RS-485
Connector pitch 5 mm, wire size 2.5 mm

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.
Current consumption: 66 mA (continuous) per STO channel per R8i
module
EMC (immunity) according to IEC 61326-3-1

Safe torque off output (XSTO OUT) (BCU-
x2 only)
To STO connector of inverter module.
Connector: RJ-45 Control panel connection (X13)
Cable length < 3 m
Connector: RJ-45 Ethernet connection (XETH) (BCU-x2
only)
This connection is not supported by the firmware.
Memory card type: SDHC SDHC memory card slot (SD CARD)
(BCU-x2 only)
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.
