Switch−on sequence for the auxiliary relay

Stop!
Overload of the charging connection in the power supply module
The controller enable for the axes may only take place when the charging
process of the DC bus is completed and the power supply module is ready for
operation.
Possible consequences:
ƒ Destruction of the power supply module
Protective measures:
ƒ Use of switching the central controller enable for the axes via the inputs and
outputs DI2 and DO1 of the power supply module (see the following
descriptions).
The switch−on sequence of the auxiliary relay 0 (see Fig. 5−8) is as follows:
1. The digital input X6/DI1 (power supply enable) of the power supply module is
switched to HIGH by the higher−level control or by the operator.
– The DC bus is charged.
2. The ready for operation output of the axis module (DO1) now switches the X6/DI2
digital input (central controller enable) of the power supply module via the relay
0.
– In the default Lenze setting of the ECS axis modules, DO1 is set to "ready". "Ready"
is only present if a specified DC−bus voltage has been reached.
3. The central controller enable for the axis module takes place via the X6/DO1 output
of the power supply module. The central controller enable DO1 only switches if the
charging process of the DC bus is completed AND the X6/DI2 input is set.
