4.1.4 Trial Operation for Servomotor with Brakes
Holding brake operation of the servomotor with brake can be controlled with the brake interlock output
(/BK) signal of the servodrive.
When checking the brake operation,take advance measures to prevent vibration due to gravity acting on
the machine or external forces. Check the servomotor operation and holding brake operation with the
servomotor separated from the machine.If both operations are correct, connect the servomotor with the
machine and perform trial operation.

4.1.5 Position Control by Host Controller
As described above, be sure to separate the servomotor and machine before performing trial operation
of the servomotor without a load. Refer to the following table, and check the servomotor operation and
specifications in advance.

JOG Operation
(Constan speed
reference input from
host controller)
Servomotor
speed
Check servomotor speed as
follows:
·Use the servomotor speed
monitor(Un000) on the panel
operator.
·Run the servomotor at low
speed.
For example, input a
reference speed of 60min
-1
,
and check to see if the
servomotor makes one
revolution per second.
Check the parameter
setting at Pn300 to see if
reference speed gain is
correct.
Simple positioning
Number of
servomotor
rotation
Input a reference equivalent to
one servomotor rotation and
visually check to see if the
shaft makes one revolution.
Check the parameter
setting at Pn200 to see if
the number of PG dividing
pulses is correct.
Overtravel (P-OT and
N-OT Used)
Whether the
servomotor
stops rotating
when P-OT and
N-OT signals
are input.
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.
