Precautions for Testing
Testing Procedure
Before applying power to each
drive
or motor, be
sure that all wiring has been performed properly.
Set the parameters correctly before testing.
Check motor motion first with no machine connected.
For a brake-equipped motor, be sure to disengage the brake
before operating the motor.
Step Operation
Step 1
Verify that wiring has been performed correctly.
Step 2
Turn on the control power to the
drive
.
Step 3
Turn on the
AC Supply
to the
drive
.
Step 4
Connect the SVON pin of CN1 connector to COM- to turn the servo on.
Step 5
Input the analog velocity command voltage with a low voltage to run the motor at a low speed.
Be sure that the actual rotational direction of the motor agrees with the direction setting.
Verify that the motor speed changes depending on the input voltage.
Step 6
After ensuring
correct direction
of actual motion, increase the command voltage gradually and
check motor motion.
Verify that the rotational speed has reached the specified speed.
If vibration occurs, increase the inertia ratio.
