The 3hp Huanyang VFD on my Harrison L5 has been working well for some time, but there are a couple of niggles.
A more complete english manual has been posted on-line;
My main niggle is the drive tripping on decelleration (if I've got the 4 jaw on)due to exceeding the DC bus limit. I may get around to installing the braking components, but until then I've spotted a setting in the new manual. You can set an anti-stall on acceleration, so if the inverter exceeds it's 150% current limit it will stop accelerating until the current falls. There's a similar setting for decelleration, it will pause until the voltage drops below the bus limit.
Most if not all of these drives sourced via ebay do not have the braking components installed. They also usually have auxillary relays missing and the RS485 comms chip. Information on retrofitting these components can be found in the Mach3 plugin thread; http://www.machsupport.com/forum/ind...c,14182.0.html
