1)Check that you can
turn the motor shaft,
after turning off the
power and separate it
from the machine.
2)Check that you can
turn the motor shaft
while applying DC24V
to the brake in case

Measures
1) Check the setups of Pr3.02 to Pr3.03 again by
setting up Pr3.00 to 0, when you use the external
analog command.
2) Set up Pr3.04 to Pr3.07 and Pr3.08 to Pr3.11 by
setting up Pr3.00 to either one of 1, 2 or 3, when
you use the internal speed command.
1) Check and make wiring so as to connect speed
zero clamp input to COM–.
2) Set up Pr3.15.
1) Check that the input voltage is applied correctly by
setting up Pr3.17 to 0, when you use SPR/TRQR
input.
2) Check that the input voltage is applied correctly by
setting up Pr3.17 to 1, when you use the P-ATL/
TRQR input.
1) Set up the desired value to Pr3.21 by setting up
Pr3.17 to 0, when you use the parameter speed.
2) Check that the input voltage is applied correctly
by setting up Pr3.17 to 1, when you use the SPR/
TRQR/SPL input.
Check the wiring/voltage of main power of the driver
(L1, L2 and L3).
If you cannot turn the motor shaft, consult with the
dealer for repair.
