5.4 Control terminals
ƒ The supply of the control electronics requires an external 24 V DC voltage at
terminals X6/+24 and X6/GND.
ƒ Connect the thermal detector of an external brake resistor to the terminals X6/T1
and X6/T2. If no external brake resistor is required, jumper terminals X6/T1 and
X6/T2.
(
Stop!
ƒ The control cables must always be shielded to prevent interference
injections.
ƒ The voltage difference between X6/AG, X6/GND and PE of the axis module
may maximally amount to 50 V.
ƒ The voltage difference can be limited by:
– overvoltage−limiting components or
– direct connection of X6/AG and X6/GND to PE.
ƒ The wiring has to ensure that for X6/DO1 = 0 (LOW level) the connected axis
modules do not draw energy from the DC bus. Otherwise, the power supply
module may be damaged.
Shield connection of control cables and signal cables
The plate on the front of the device serves as the mounting place (two threaded holes M4)
for the shield connection of the signal cables. The screws used may extend into the inside
of the device by up to 10 mm. For optimum contact of the shield connection, use the wire
clamps from the ECSZS000X0B shield mounting kit.
