4.2.2. Position Control by Host Controller
If the position control algorithm of the host controller has not been
established or finalized, disconnect the servomotor from the equipment
before performing a trial operation. This will prevent the servomotor from
running out of control and damaging the equipment.

Motor speed
Check motor speed as follows:
• Use the speed monitor (Un000) on
the Panel Operator.
• Run the servomotor at low speed.
Input a reference speed of 60 rpm,
for example, to see if the servomotor
makes one revolution per second.
Check the parameter
setting at Pn300 to see
if the reference speed
gain is correct.

Positioning
Number of
motor
rotations
Input a reference equivalent to one
servomotor rotation and visually
check to see if the shaft makes one
revolution.
Check the parameter
setting at Pn201 to see
if the number of
dividing pulses is
correct.
Overtravel

N-OT Used)
Whether the
servomotor
stops rotating
when P-OT
and N-OT
signals are
applied
Check to see if the servomotor stops
when P-OT and N-OT signals are
input during continuous servomotor
operation. Review P-OT and
N-OT wiring if the
servomotor does not
stop.
