If an inductive load is connected to X6/DO1, a spark suppressor with a limiting
function to max. 50 V
± 0 % must be provided.
Power supply enable of the power supply module
ƒ The X6/DI1 input serves to start the controlled charge of the DC bus by the charging
thyristor.
ƒ Only when the charging process is completed, which is displayed through the ready
for operation message at the X6/DO1 output of the power supply module, the
connected axis modules may be enabled. Otherwise, the charging thyristor would be
overloaded.
X6/DI2 − central controller enable for the connected axis modules via DO1
ƒ The X6/DI2 input can be used together with the X6/DO1 output as centrally
controlled controller enable for all connected axes. The DO1 output only switched if
the DC bus has been charged completely without any trouble. This automatically
ensures that the axis modules cannot be enabled too early and consume energy
from the DC bus too early.
ƒ For this purpose, wire the X6/DO1 output with the X6/SI1 inputs of the axis
modules for controller enable.
If required, one further contact can be connected in series for each axis module to be
able to inhibit and enable the individual axis modules during operation.
ƒ In order that the output of the power supply module X6/DO1 is set to "HIGH", the
following conditions must be met:
– The power supply module is ready for operation.
– The DC bus is charged.
– X6/DI1 = HIGH (the controller enable input of the power supply module is
triggered)
– The X6/DO1 output of the power supply module requires the 24 V supply voltage
via terminal X6/D24.
