4.1.3 Trial Operation with the Servomotor Connected to the Machine
！
WARNING
·
Follow the procedure below for trial operation precisely as given.
·
Malfunctions that occur after the servomotor is connected to the machine not only damage the machine, but may
also cause an accident resulting in death or injury.
Follow the procedure below to perform the trial operation.
To power supply
Secure the servomotor flange to the
machine, and connect the servomotor shaft
to the load shaft by using a coupling.
To host controller
Step
Description Check Method and Remarks
1
Turn the power ON, and make the settings for the
mechanical configuration related to protective
functions such as overtravel and brake.
Refer to 4.3 Setting Common Basic Functions.
When a servomotor with brake is used, take advance
measures to prevent vibration due to gravity acting on
the machine or external forces before checking the
brake operation. Check that both servomotor and brake
operations are correct.
For details, refer to 4.3.4 Setting for Holding Brakes .
2
Set the necessary parameters for the control mode
used.
Refer to 4.5 Operating Using Speed Control with
Analog Reference , 4.6 Operating Using Position
Control , and 4.7 Operating Using Torque Control for
control mode used.
3
Connect the servomotor to the machine with the
coupling,etc.,while the power is OFF.
4
Check that the servo drive is servo OFF status and
then turn ON the power to the machine (host
controller). Check again that the protective function in
step 1 operates normally.
Refer to 4.3 Setting Common Basic Functions .
For the following steps, take advanced measures for an
emergency stop so that the servomotor can stop safely
when an error occurs during operation.
5
Perform trial operation with the servomotor connected
to the machine, following each section in 4.1.2 Trial
Operation for Servomotor without Load from Host
Reference .
Check that the trial operation is completed according to
the trial operation for servomotor without load. Also,
check the settings for machine such as reference unit.
6
Check the parameter settings for control mode used in
step 2.
Check that the servomotor rotates matching the
machine operating specifications.
7
Adjust the servo gain and improve the servomotor
response characteristics, if necessary.
The servomotor will not be broken in completely during
trial operation. Therefore, let the system run for a
sufficient amount of time to ensure that it is properly
broken in.
8
Thus, the trial operation with the servomotor
connected to the machine is complete.
