Q? You have 3 slot in PF753 - does the Power supply card take one of the slots?
Q? With the dual encoder input could one of the encoders be used for a speed reference and the second encoder be used for motor feedback to improve speed regulation?
Q? Safe speed monitor when used with incremental encoder must be 5 vdc not 12 vdc
Q? Why there is no Feedback information on the Safe Torque Off (750-S )?
Q? If we want to use safe speed card, in safe torque mode ( to eliminate safety relay) do we still need an encoder?
Q? Is the Aux Power Supply the board that allows the drive control and HIM to be powered up without the line power being energized?
Q? Will torque prove be added to PowerFlex 753?
Q? When will 600V be made available, how about 230V?
Q? Will the PF750 series be able to use the 20-COMM-R with PLC5 or SLC 500 based systems?
Q? Will a PF753 specific Ethernet card be forthcoming or will we always need to use the 20-COMM-E?
Q? Can a 20-COMM-E be used in conjunction with the native Ethernet port on a 755 to accommodate "daisy-chaining" of the drives.
Q? There is no standard 4-20mA input for the PF753. Is this correct? Must use an option card?
