1)
If the connection is used to activate the external holding brake (S1/S2), then the cabling is not permitted to exceed a total length of 3 m.
If the holding brake is connected via an additional external relay contact (ground-in e.g. via the S1/S2 connections) instead of via the internal transistor, then
the internal quenching circuit has no effect! In this case, the customer must make sure that neither the relay contact nor the braking coil are damaged when
switching off the brake. This can be done by interconnecting the coil or - better still - interconnecting the contact with a quenching circuit.
Danger!
The connections for the motor holding brake are isolated circuits. These connections are therefore
only permitted to be connected to devices or components that have sufficient isolation in accordance
with IEC 60364-4-41 or EN 61800-5-1.
Caution!
If B+ and B- are swapped when connecting the permanent magnet holding brakes, then the brakes
cannot be opened! ACOPOSmulti inverter modules cannot determine if a holding brake is connected
with reverse polarity!
Warning!
Temperature sensors are only permitted to be connected to the X4A/T+ and X4A/T- connectors on an
ACOPOSmulti module under the following conditions:
•
There is no ACOPOSmulti plug-in module in SLOT1 on the ACOPOSmulti module with a tem-
perature sensor connected to T+ and T-
Otherwise, the temperature monitoring functions on the ACOPOSmulti module may become ineffec-
tive, which in extreme cases can cause the hardware (e.g. motors) connected to the ACOPOSmulti
module to be destroyed!
