Analog outputs AO1 and AO2 (XAO)
XD2D connector
RS-485 connection (X485)
Safe torque off connection (XSTO)
Safe torque off output (XSTO OUT)
Control panel connection (X13)
Ethernet connection (XETH)
SDHC memory card slot (SD CARD)
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.
Connector pitch 5 mm, wire size 2.5 mm
0...20 mA, R < 500 ohm
load
Frequency range: 0...500 Hz
Resolution: 11 bit + sign bit
Inaccuracy: 2% of full scale range
Connector pitch 5 mm, wire size 2.5 mm
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 switch
Connector pitch 5 mm, wire size 2.5 mm
Physical layer: RS-485
Connector pitch 5 mm, wire size 2.5 mm
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
To STO connector of inverter module.
Connector: RJ-45
Cable length < 3 m
Connector: RJ-45
This connection is not supported by the firmware.
Memory card type: SDHC
Maximum memory size: 4 GB
