A7 Changes and new functions
Control devices starting with the manufacturing number 3942xxx with the software release 3.0 have
the following differences compared with previous devices.
Changes:
•
When connecting the control device, it is no longer necessary to remove the front plate.
•
The current supply of the control unit board is also executed plugged-in.
•
The installation as well as the exchange of the control device has been simplified by means of
constructional measures.
•
The freely programmable special outputs and the additional inputs have been preset as follows by
the factory:
"SK1"-Special contact 1
Contact K11-K12 is closed when the speed is higher than 0.3 m/s.
"SK2"-Special contact 2
Contact K21-K22 is closed if the nominal speed is exceeded by 10 %.
"SK3"-Special contact 3
Contact K34-K33 is open if the motor temperature monitoring is triggered.
The running speeds "V_ZE1 - V_ZE3" are allocated to the additional inputs "ZE1 - ZE3".
•
The contact "RB- Controller active" is preset from the factory in a way that the relay connects the main
contactors (Factory setting INVERS instead of STANDARD used up to now).
•
The terminal designation of the special outputs has been changed in order to be better
understandable.
•
The control inputs can be directly connected to an external voltage of 24 V without being modified (see
2.3.3)
Expansions:
•
The input "VZ" is used for post-adjustment (except with installation type "Running gear").
•
Besides the additional input "ZE", two further additional speeds are available (see above).
•
It is possible to connect an encoder with a pulse resolution of 64 - 1024 per revolution and track.
•
The input of the encoder evaluation wiring has been completed by a constant current source. (Pre-
resistors probably needed up to now are no longer necessary).
