11.3 Control circuit to the power connection
The control circuit recommended by INDRAMAT represents the function
principle.
The choice of the control and its efficiency depends on the range of func-
tions and the course of efficiency of the entire system or machine.
Therefore, it is the manufacturer’s responsibility to make this choice.
The stand-by message is output over a relay contact (make contact). If
the stand-by contact closes, the drive is then ready for input power. It is
thus used as a condition for connecting the line contactor (see Fig. 11-6)
The ready-for-operation contact opens when:
•
there is no control voltage for the DKC,
•
24 V are not applied a the E-stop input if the E-stop function is acti-
vated (see function description).
•
if there are faults in the drive.
Requirement:
The E-stop input is available if the E-stop function in the software is acti-
vated (see function description).
If during the following events:
•
the limit switch trips
•
the E-stop is pressed
•
power is switched off (power off)
it becomes necessary to activate the internal drive error response as fast
as possible, use the E-stop function.
If the E-stop function is not used, the drive-internal error response will not
be activated until the line contactor K1 opens and as a consequence is
recognized as "undervoltage in the DC bus" in the drive controller.
