Another possibility is an incorrect connection between the
analog output terminals on the axes (DRV1 and Gnd) and
the analog reference input of the LVD drive
Check wiring of the analog reference signal cable and the
feedback signal cable (encoder). If correct, invert the
analog input on the LVD drive
See below if the motor now runs in the wrong direction.
Motor spins slowly when
the drive is enabled.
The drive is not governed by the Axis Controller.
Check the cable between the encoder output and the Axis
Controller.
Check the analog reference connecting cable between t he
drive and the Axis Control.
Check that the analog output of the Axis Control is
carrying voltage.
Motor stationary with no
torque.
Check that, with the drive enabled, the display shows the
message run. If not, re-check LVD programming and
wiring.
Motor spins in wrong
direction.
Check the I/O signals to and from the Axis Control.
Invert encoder signals A & /A and the analog reference
inputs on the LVD drive
