(Ready)
In order to avoid unnecessary down time, machinery and plant require
continuous monitoring. The DDS 2.1 drive controller caters to this need
with a signal contact.
The potential-free signal contact "Bb" (Ready) on connector X3 pin 6/7
makes it possible to pinpoint the affected machine in the event of a drive
error in the associated NC control or signalling device (see Fig. 67).
The signal issued by the drive controller can be indicated through an NC
control or a signalling device.
The Bb contact opens whenever:
– there is an interruption in the control voltage
– the control voltage is applied, but there is an error in the AC servo drive
The Bb contact remains closed when:
– the control voltage is continuously applied
– the servo drive is free of errors
