Hello, as pointed out on your initial post, the implementation of that application requirement would be possible configuring the MOP (Motor Operated Potentiometer) feature of the PowerFlex 755 with the help of 2 digital inputs. In the scenario presented, it looks like there are not spare inputs ...

Hello Choong, I cannot find any indication of the start up sequence being inconsistent within different power rated Kinetix 5500 servo drives. By product design, the start up sequence shall apply equally in principle to all the power ratings. It is still highly recommended to apply first the Control ...

Hello, please note that the local Rockwell distributor or commercial channel should be the first point of contact to discuss the exact replacement of a PowerFlex 700S phase II drive with a more modern drive. Please also note that the parameter set, terminal connections, physical dimensions ...

Hello, the power up sequence of the Kinetix 5500 servo drive, as mentioned early on this thread, is clearly documented on Publication Kinetix 5500 Servo Drives User Manual. By design specifications, the Kinetix 5500 servo drive needs to be powered up following that order. After applying the ...

EDIT: linkified for convenience -FL I think one thing missing here is to link the value of Analog Input 1 (parameter 800) to parameter 10 [Speed Ref 1]. This action is confirmed on Technical note https://rockwellautomation.custhelp.com/app/answers/answer_view/a_id/441489 On this specific ...

The PowerFlex 525 drive comes with a digital input built into the terminal block (terminal 7) able to read pulse train signals up to 100 kHz at 24V. PWM (Pulse Width Modulation) is a general term that refers to the way that most of the AC typical variable speed drives operate at the inverter section ...

EDIT: removed external formatting -FL Hello, there is some conceptual guidance on how to apply a Speed Trim Follower scheme with AC drives via the following document: https://literature.rockwellautomation.com/idc/groups/literature/documents/wp/drives-wp001_-en-p.pdf This other technote includes ...

For externally mounted braking resistors, the recommendation is to protect the drive from resistor temperature rise. This is done typically by a normally closed contact from an internal thermostat in the resistor. This signal is often used to open a contactor upstream the drive and remove the supply. ...

Hello, Thanks for sharing this problem. It looks as if the drive is being used within a Pump Jack oil well application. I am hoping this thread could be visible by other Engineers that have used the PowerFlex 755 drive on this particular type of application, very common I believe in countries ...

Hello, one of the most common load sharing techniques is the speed leader/torque follower described previously. That principle is also applicable to the PowerFlex DC drives. There is further detailed information available from Load Sharing between PowerFlex DC Drives where key parameter settings ...

Hello, you are very welcome. There are some technical notes available from the Rockwell Knowledgebase that could help with the task ahead. For example for the PowerFlex 753 drive PowerFlex 753: Configuring 2 preset speeds using 1 Digital input can be useful. For the PowerFlex 525 drive PowerFlex ...

No problem, you are welcome. I agree with your way of thinking. With an encoder feedback, the torque loop inside the PowerFlex 750 class drive should be quick enough to acknowledge faster variations of the torque signal. Without an encoder feedback, the torque loop may miss signals above the ...

Hello, think of bandwidth in this context as how quick the internal Torque Loop inside the drive can work. The higher the bandwidth, the faster the torque loop can react to torque variations. The faster the torque loop is, the more accurate the torque regulation will be as well. The speed and torque ...

Hello, d003[Output Current] is the total output current present at terminals T1, T2 and T3 of the drive, as measured and calculated by the internal drive circuitry. The total output current can be defined as: where Torque Current is the amount of current in phase with the fundamental voltage component ...
