The following table shows the 4 data bits that MOVI-SWITCH

1EM sends back to the
AS-Interface master via the AS-Interface:
6.4.4
Assigning the AS-Interface slave address
SEW-EURODRIVE supplies MOVI-SWITCH
®
1EM with AS-Interface with address 0.
You have the following options for assigning the AS-Interface address of MOVI-
SWITCH
®
1EM (addresses 1A – 31A, 1B – 31B):
•
Addresses are assigned automatically
within a configured AS-Interface system
when replacing a MOVI-SWITCH
®
1EM drive.
The following prerequisites must be fulfilled:
– The new MOVI-SWITCH
®
1EM drive must have address 0.
– If you need to replace several MOVI-SWITCH
®
1EM drives, you must exchange
them individually (one after another).
•
Manual address assignment via the plant master
Connect the drives to the AS-Interface cable one after another. Doing so prevents
several MOVI-SWITCH
®
1EM drives from being assigned the same AS-Interface
address.
•
Manual address assignment using a hand-held AS-Interface programming
device.
Observe the notes in the following chapter when connecting the MOVI-SWITCH
®
1EM drive to the AS-Interface cable.
