4.1.2 Step 2: Trial Operation with the Servomotor Connected to a Load
Before proceeding to step 2, repeat step 1 (servomotor trial operation without a load) until
all concerns including parameters and wiring have fully satisfied expectations.
After step 1 has been completed, proceed to step 2 for trial operation with the servomotor
connected to the equipment. The servo amplifier is now adjusted in the following ways to
meet the specific equipment’s characteristics.
• Using autotuning to match the servo amplifier to the equipment’s characteristics.
• Matching the direction of rotation and speed to the equipment’s specifications.
• Checking the final control form.
Follow the procedures below to perform the trial operation.
1. Make sure power is OFF.
2. Connect the servomotor to the equipment.
See 2.1 Servomotors for more details on connecting the servomotor.
3. Use autotuning to match the servo amplifier to equipment characteristics.
See 6.3 Auto-Tuning.
4. Operate the servomotor by reference input.
As in step 1 (Servomotor Trial Operation without Load), execute operation by reference
input as described in 4.1.1 Step 1: Trial Operation for Servomotor without Load. Tune
to match the host controller at this time, as well.
5. Set and record user settings.
Set parameters as required and record all settings for use later in maintenance.
Note: The servomotor will not be broken in completely during the trial operation. Therefore, let the system run for a
sufficient amount of time after the trial operation has been completed to ensure that it is properly broken in.
Follow the procedure below for step 2 operation precisely as given.
Malfunctions that occur after the servomotor is connected to the equipment not only damage
the equipment, but may also cause an accident resulting in death or injury.
