Note
Ensuring the function of digital inputs
An open input is interpreted as "low".
To enable the digital inputs (DI) to function, terminal M2 must b
e connected.
This is achieved through one of the following measures:
Also route the reference ground of the digital inputs.
A jumper to terminal M. (
This removes the electrical isolation for these digital
inputs.)
Note
If the 24 V supply is brief
ly interrupted, then the digital outputs are deactivated during this
X124: Electronic power supply
Table 4- 27 Terminal block X124
+ Electronic power supply Voltage: 24 V DC (20.4 to 28.8 V)
Current consumption: max. 1.0 A (without DRIVE-
CLiQ or digital outputs)
Max. current via jumper in connector: 20 A (15 A
according to UL/CSA)
M Electronics ground
Max. connectable cross-section: 2.5 mm²
The maximum cable length that can be connected is 10 m.
Note
Looping through the supply voltage
The two "+" and "M" terminals are jumpered in the connector. This ensures that the supply
voltage is loope
d through.
The power can be supplied via terminals X41.1/2 of the Power Module.
Note
Screw terminal block on tightly
The terminal block must be screwed on tightly using a flat
-bladed screwdriver.
