I am amazed. That has to be the fastest reply I ever got from any corporate channel. Sometimes you don't get a reply and the fastest replies are usually in a day or two. I appreciate the fast reply and the info. Very impressed.
Thank you for the comment! Let us know how the drive works out for you. Also, there is a basic start up video on the Invertek drive on our channel if you need it.
+nitin mathur There are two parameters to look at: • Parameter L8-01, verify it is set to 0, this is the default value, this sets the drive up for an external DB resistor. • Parameter L3-04 which should be set to 0 which is the default, change it to 3. This sets up the drive for stall prevention with braking option during deceleration.
Can I time the run of a motor with a vfd? I am running 3 motors on 3 different VFDs for 3 different "feed" conveyors. I need to create a % mix, feeding from the 3 conveyors onto 1 main production conveyor. Fine tuning the mix requires me to change the speeds of the 3 conveyors to supply the exact required volumes onto the production conveyor. Can you please advise?
If the VSF is interacted a safety function such as STO, do we need to use a safety module in the structure to protect the machine? I suppose the PL of machine is C.
The ratings for the STO function can differ from drive to drive. This should be listed in the manufacturer's manual and may have a rating that says Class 1 Division 2 or something along those lines. Installation with or without safety relays are also specified in the manual and if one is not required, generally a wiring diagram is included. I hope this helps!
Not exactly, but very close. S-curve simply adds a"roll-in and roll-out" feature if you will. It directly effects the very beginning and the very end of speed change when commanded by the reference, ok? Otherwise RAMP to STOP is exactly the same, the S-curve just adds a little time it.
I was on your website and looked at vfd. I guess im a little confused. Can I use a vfd to change speed of a 120v 60hz single phase motor or would I have to replace the motor with a 3 phase motor to use a vfd.
It depends on your motor. If you have a capacitor start motor, then yes it would be better to replace it with a three phase motor to use a VFD. If it is a SP (shaded pole) or PSC (permanent split capacitor), then you might be able to use the Invertek ODE2 series. There are some single phase output motors within that series. Just remember to size the drive to your motor specifications. (current and HP should be on the motor's nameplate). The single phase drives in this series have a '-01' at the end of the part number. Search by brand on top then click on Invertek-->drives-->AC Drives. I hope this helps.
