EJ7411 | 1-channel motion interface, BLDC motor, 48 V DC, 4.5 A, with incremental encoder · 0 次阅读

Connection

The PCB footprint can be downloaded from the Beckhoff homepage.

Notice

Damage to devices possible!

The pins named with “NC” must not be connected.
Before installation and commissioning read the chapters Installation of EJ modules and Commissioning!

Shielding

Feedback signal, sensors and actuators should always be connected with shielded, twisted paired wires.

Notice

Cable fire and defect possible!

The load voltage (supply of the DC link +8 V ... +48 V) is not short-circuit proof, cable fire and defect are possible!

Use an overcurrent protection device for the load voltage.
Dimension the overcurrent protection device so that the maximum current is limited by 3 times the nominal current for a maximum of 1 second.

If necessary, supplement the hardware setup by the following components:

The EJ9576 brake chopper module and a ZB8110 braking resistor.
The brake chopper module may be necessary if too much energy is fed back to the load voltage during braking procedures.

Enabling the output stage

Apply 24 V to the "24V Hardware Enable" input (pin 28) to enable the axis!
