Description
Turning off the start signal with
orientation command (X22) on
after stopping the motor by orien-
tation control, the present position
is checked again after the set time
elapses and the orientation com-
plete signal (ORA) or orientation
fault signal (ORM) is output.
Not checked.
Set the number of pulses of the
encoder. Set the number of pulses
before multiplied by four.
Orientation is executed from the
current rotation direction.
Orientation is executed from the
forward rotation direction.
Orientation is executed from the
reverse rotation direction.
Servo rigidity is (response level
during position control loop) at
orientation stop can be adjusted.
Lag/advance compensation gain
can be adjusted.
Make adjustment when the motor
runs back at orientation stop or
the orientation time is long.
Encoder
Clockwise direction as viewed from
A is forward rotation
Encoder
Counterclockwise direction as viewed
from A is forward rotation
Set the region of speed feedback
control.
Encoder feedback control is invalid
Set when the rotation is unstable
or response is slow.
Set the number of pulses of the
encoder. Set the number of pulses
before multiplied by four.
When the motor speed reaches or
exceeds the speed set in Pr. 374
during encoder feedback control,
real sensorless vector control, or
vector control, over speed (E.OS)
occurs and stops the inverter out-
put.
