RE: SyncLink VS TLink

Posted By Enrique Oct 01, 2025 07:58:36 AM
Found In Egroup: Drives, Motion Control & Low Voltage Products \ view thread
Hello GAAM, We can send the encoder speed and position with Datalinks using EtherNet/IP network, but the data transfer will be much slower. SynchLink and T-Link data transfer is 125 usec and Datalinks is 2 msec (using min RPI allowed). We cannot guarantee it will be possible to do the application ...

Hello GAAM, Tlink is not compatible with Synchlink. So you cannot migrate only one of the existing PowerFlex 700S drives to PowerFlex 755TS. It's necessary to replace both drives. The transmitter 700S drive is sending encoder 0 speed and position to the receiver 700S drive. With the PF755TS using ...

You can use two different deceleration ramps using decel time 1 (537) and decel time 2 (538) . You can switch from decel 1 to decel 2 with a digital input (DI Decel 2 - param 180) or by network . ------------------------------ Enrique Fabregas EMEA Commercial Project Engineer Rockwell Automation ...

RE: Help needed for PowerFlex Product Serial Number

Found In Egroup: Drives, Motion Control & Low Voltage Products \ view thread
Hi Adam, You can use Drive Explorer/DriveExecutive/CCW software packages to determine the PowerFlex Drive's Host Serial number from the main control board or the power board test. But this is an internal serial number that does not reflect the real Serial Number that is printed on drive nameplate. ...

RE: PF753 Decel Inhibit Fault while running

Posted By Enrique Apr 16, 2024 10:10:00 AM
Found In Egroup: Drives, Motion Control & Low Voltage Products \ view thread
I saw this fault in fan applications or high inertia loads because the bus voltage regulation is active and the drive can not follow the programmed deceleration. If the deceleration time is not critical for the application, I suggest to ignore this fault in parameter 0:409[Dec Inhibit Actn]. Best ...

Hello, While the drive is stopping, the Active bit is High and you are forcing the Stop bit to High. In this situation, the drive changes to Stop Asserted state (you are actively giving a stop command) and the ready bit goes to Low. You can see the Stop Asserted message on the HIM. When the ...

Hello Leebehzite, If you want to use a fixed IP address, you have to set parameter C128[Net Addr Sel] to Parameters and set the IP Address and Subnet Mask in parameters C129 to C136. Setting a Gateway Address is optional. After changing any of these parameters, you have to cycle power to the drive ...
