Description
Check Method and Remarks
1
Match the reference pulse form with the pulse output form
from the host controller.
Set the reference pulse form with Pn004.2.
2
Set the reference unit and electronic gear ratio so that it
coincides with the host controller setting.
Set the electronic gear ratio with Pn201(or
Pn203)/Pn202.
3
Turn the power and the servo ON input signal ON.
4
Send the slow speed pulse reference for the number of
servomotor rotation easy to check (for example, one
servomotor revolution) from the host controller in advance.
Set the servomotor speed to100rpm for the
reference pulse speedbecause such speed is safe.
5
Check the number of reference pulses input to the servo
drive by the changed amount before and after the Un013 and
Un014(input reference pulsecounter)[pulse] were executed.
Refer to
5.1.6 Operation in Monitor Mode
for how it
is displayed.
6
Check whether the actual number of servomotor
rotationsUn009, Un010 coincides with the number of input
reference pulses.
Refer to
5.1.6 Operation in Monitor Mode
for how
it is displayed.
7
Check that the servomotor rotation direction is the same as
the reference.
Check the input pulse polarity and input reference
pulse form.
8
Input the pulse reference with the large number of
servomotor rotation from the host controller to obtain the
constant speed.
Set the servomotor speed to 100rpm for the
reference pulse speed because such speed is safe.
9
Check the reference pulse speed input to the servo drive
using the Un008in Monitor Mode. (input reference pulse
speed)[rpm].
Refer to
5.1.6 Operation in Monitor Mode
for how it
is displayed.
10
Check the servomotor speed using the Un000 in Monitor
Mode. (servomotor speed) [rpm].
Refer to
5.1.6 Operation in Monitor Mode
for how it
is displayed.
11
Check the rotation of the servomotor shaft.
To change the servomotor rotation direction without
changing the input reference pulse form, refer to
4.3.2 Switching theServomotor Rotation
Direction
. Perform the operation from step 8 again
after the servomotor rotation direction is changed.
12
When the pulse reference input is stopped and servo OFF
status is entered, the trial operation for servomotor without
load in position control mode is complete.
