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.
