Check the input signal circuit again, and
check
that
the

input
(between the V-REF+ and V-REF-) is 0 V.
Refer to the above figure for input signal circuit.

Turn the servo ON input signal (/S-ON).
If the servomotor rotates at extremely slow
speed, refer to

Send the command for the number of
servomotor rotation easy to check ( for
example, one servomotor revolution) from the
host controller in advance, and check the sent
number of rotation and actual number of
rotation by visual inspection and the

If the sent number of rotation and actual
number of rotation in step 11 are not equal,
correctly set the Pn200 (PG divided ratio)
outputting the encoder pulse from the
servodrive.

When the speed reference input is set to 0 V
and servo OFF status enters, the trial
operation for position control with the host
controller is completed.

When the speed reference input is set to 0
V and servo OFF status enters, trial
operation for servomotor without load is
completed.
