Yes, That's my second reset.

I'm happy with mine, but I wish I could add an external braking resistor.

Sigh, resetting the drive to defaults cured the reverse issue. No idea
what setting could have been set to cause some sort of a reverse bias

issue.

I'm having some issues commissioning my HY VFD. 4kw unit driving a 5hp
3450rpm motor at 30hz max frequency (temporary 2 pole motor, 4 pole
motor
is in the mail). Works great in "forward", but when it accels in
reverse it
trips out and throws an E.OC.N error. Which appears to be an over
current
error.
I've flipped 2 leads to the motor, reversing the physical rotation and
it
still works great in vfd "forward", proving that the motor and
mechanical
aspects work in both directions. But the VFD does not. Accel times are
quite conservative/slow. Problem happens about 1 second into
acceleration.
No clue.... There don't seem to be any relevant settings. Problem
happens
regardless of control method, modbus or operator panel.
Unrelated, but wow, at low speeds this VFD seems to throw off a ton of
interference. The symptom I've noticed is that my usb mouse connected
to
the PC in the control cabinet that also houses the VFD basically gives
up
on life if the motor is running below 15hz. USB dongle modbus was
fairly
impacted as well until I grounded the cable shield to the pc case.
Just to make this slighlty more on topic. Is there a config somewhere
for
maximum spindle RPM? With the drive configured correctly it won't
overspeed
the motor, but it would be nice if the software was aware of a top end
for
spindle speed as well.
Thanks,
Dave
