Lemo, that Keling motor works fine, we have at least one case using the same motors. A simple differential line driver circuit may be needed for encoders if they are "single ended" type.
Unlike most of the lower cost drives, VSD-A has active current regulation so in practice it is indestructable by driving motor in any imaginable way. Try reversing directions or crash it to hard stop at full speed, no smoke will come out (not from drive, motor or fuse) since current gets clamped to user specified maximum value. Drive has 12.5A peak current limit but I'm planning to inrease it to 16A for short peak loads. Upgrade to 16A can be done with software to every sold drive by user.
All these current limits are in software only. It means that for example 12.5A is the highest current that drive is willing to output. It is nowhere near breakdown level (output has 20A continous rated parts). |
