How can a Powerflex755TL VFD be configured to detect loss of power at the motor (power disconnect at the motor) as a fault and remove the run command to the motor?

The Allen-Bradley PowerFlex 755T VFD can be configured to detect a loss of power at the motor and remove the run command by utilizing the Safe Torque Off (STO) function. This function ensures that torque is not applied when required for safety. Additionally, the drive logic command word includes bits for fault detection and control, such as the "Clear Faults" bit, which can be used to respond to power loss conditions. Proper ladder logic programming in the Logix Designer application can also be implemented to monitor motor power loss and execute the required safety actions.

Page 19: User-Supplied Equipment
Getting Started Chapter 1 User-supplied Equipment To configure the built-in EtherNet/IP interface, you must supply the following: • A small flat-blade screwdriver for setting the network address switches. • An Ethernet cable (for details, see the EtherNet/IP Media Planning and Installation Manual, ODVA publication 148, available on the ODVA website at http://odva.org/Home/ODVATECHNOLOGIES/...
Page 20: Choose An Ethernet Switch
Chapter 1 Getting Started Choose an Ethernet Switch If the built-in EtherNet/IP interface is used to communicate with a controller that has multicast connections, a managed switch that supports IGMP snooping is suggested. EtherNet/IP implicit (I/O) messaging can be configured to use IP multicast to distribute I/O control data, which is consistent with the CIP-based network Producer/ Consumer model.
Page 21: Safety Precautions
Getting Started Chapter 1 Safety Precautions Read the following safety precautions carefully. ATTENTION: • Risk of injury or equipment damage exists. Only personnel familiar with drive and power products and the associated machinery can plan or implement the installation, start up, configuration. Only qualified personnel can perform subsequent maintenance of the drive by using this built-in interface.

Page 26 Chapter 2 Configure the Interface IMPORTANT Regardless of the method that is used to set the interface IP address, each node on the EtherNet/IP network must have a unique IP address. To change an IP address, you must set the new value and then remove and reapply power to (or reset) the interface.

Configure the Interface Chapter 2 Setting Communication A hierarchy determines the type of device with which the interface exchanges data. In a Controller hierarchy, the interface exchanges data with the Hierarchy ControlLogix® controller or another communication bridge. When a multicast I/O connection is used or when the interface does not have a valid gateway address, the controller must be on the same IP subnet as the interface to establish an I/O connection.

Page 41 Configure the Interface Chapter 2 IMPORTANT Always use the datalink parameters in consecutive numerical order. Start with the first parameter. For example, use 0:340…344 to configure five datalinks to read data. Otherwise, the network I/O connection size is larger than necessary, which needlessly increases controller response time and memory usage.

Datalinks for PowerFlex 755T peripherals are locked when the peripheral has an I/O connection with a controller. For example, the built-in EtherNet/IP interface on PowerFlex 755T drives only, and option modules such as an encoder or a communication module. When a controller has an I/O connection to the drive, the drive does not allow anything that could change the makeup of the I/O connection in a running system.
