Description

Overview

Essential details：8BVE0500HC00.000-1  ACOPOSmulti auxiliary supply modules

8BVE expansion modules allow the DC bus and 24 VDC power supply of an ACOPOSmulti drive system to be distributed to multiple 8B0M mounting plates. This makes it possible to implement distributed units within an ACOPOSmulti drive system. The module is equipped with corresponding cable outlets for this. In addition, ACOPOSremote
and ACOPOSmotor drive systems can be connected to an ACOPOSmulti drive system via 8BVE expansion modules.

Fuse protection must be provided for the cable outlets for the DC bus and 24 VDC connection from the 8BVE expansion modules. Fuse holders for fuses are thus installed in the 8BVE expansion modules accordingly. The fuses necessary for operation must be dimensioned based on the application and installed by the user in the 8BVE expansion modules before commissioning. Suitable fuses are available as 8BXS fuse sets.

All fuse holders are thermally monitored. The monitoring status is indicated by LEDs. If the 8BVE expansion module is overloaded, this will be additionally indicated to the user over special relay contacts (ALARM) for additional evaluation.

An additional PE connection must be made between two 8BVE expansion modules in order to meet the conditions necessary for the ACOPOSmulti drive systems mains connection on all 8B0M mounting plates that are connected using 8BVE expansion modules. This additional PE connection must be made with the same wire cross section as the PE wire used for the DC connection (at least 2.5 mm² with protected wiring or 4 mm² with unprotected wiring).

8BVE0500HC00.000-1  ACOPOSmulti auxiliary supply modules

ACOPOSmulti drive systems detect a power failure and are able to initiate immediate shutdown of the connected motors.
The braking energy that occurs during braking is returned to the DC bus and can be used via the auxiliary supply module for the 24 VDC power supply of the ACOPOSmulti drive system. During braking, the ACOPOSmulti drive system as well as connected encoders, sensors, control and HMI systems and safety systems can be supplied with 24 VDC.
There are use cases in which the braking energy occurring is not sufficient for the 24 VDC power supply until the motors come to a standstill or in which the 24 VDC power supply is still required for a short time after the motors have come to a standstill in order to properly shut down connected control and HMI systems or to back up data from the ACOPOSmulti drive system.
In these cases, an external 24 VDC source (e.g. UPS) connected to the input of ACOPOSmulti auxiliary supply module 8B0C0320Hx00.00A-1 can ensure the 24 VDC power supply of the ACOPOSmulti drive system and connected external 24 VDC loads for a sufficiently long period of time. B&R recommends switching off unnecessary
24 VDC loads. This can be done using the switchable 24 VDC output of the auxiliary supply module, for example. 1)
In addition, ACOPOSmulti auxiliary supply module 8B0C0320Hx00.00A-1 offers the possibility of operating ACOPOSmulti drive systems using only an external 24 VDC supply without having to supply the DC bus. In this way, partial commissioning of the drive system can be easily carried out.
