WARNING
The following procedure causes the motor shaft to rotate.
Setting Up Your System for the Motor Matching Procedure
Before beginning the
Motor Matching procedure, set up your system as follows:
1.
The
Motor Matching procedure below is a bench top procedure—temporarily
connect the drive, motor, indexer, and PC running Motion Planner (or a palm PC
running Pocket Motion Planner), but do not permanently mount the components yet.
2.
Properly secure the motor
3.
Set the motor current at the value recommended for your motor.
4.
Do not attach a load to the motor shaft, or anything else that affects or changes the
inertia of the rotor. The characteristics you are matching are those only of the drive/
motor combination.
5.
Before beginning the
Motor Matching procedure, you must use Motion Planner or
Pocket Motion Planner to configure the drive for your motor. See
Step 3 of
Chapter 2 Installation for instructions.
6.
Apply AC power when necessary to perform the steps below.
Motor Matching Procedure
1.
Apply power to the drive, enable the drive, and allow the drive and motor to reach a
stable operating temperature. This will take at least 5 minutes, and may take up to
30 minutes. For optimum results, perform the matching procedure at the same
ambient temperature at which your application will operate.
2.
Launch the
Interactive Motor Matching procedure of Motion Planner (MP) or Pocket
Motion Planner (PMP).
3.
Select the
PHASE A OFFSET button.
4.
Set the motor speed to the recommended value for your motor.
5.
Vary the motor speed about the recommended value, and find the most resonant
operating speed. (Varying the speed makes resonance more noticeable.) You can
find the
resonant speed by touching the motor lightly with your fingertips as you
vary the speed. When you notice the strongest vibrations and increased noise, the
motor is running at a resonant speed. Note the actual speed; you will use it in the
steps below.
6.
Change the offset adjustment using the left and right arrow keys or by using the
touch screen (if available). Adjust the offset for smoothest operation.
7.
Select the
PHASE B OFFSET button.
8.
Change the offset adjustment using the left and right arrow keys or by using the
touch screen (if available). Adjust the offset for smoothest operation.
9.
Select the
PHASE B BALANCE button.
10. Set the motor speed to one half the speed found in
Step 5. Vary the motor speed
about this setting, and find the most resonant operating speed. Change the balance
adjustment using the left and right arrow keys or by using the touch screen (if
available). Adjust the balance for smoothest operation.
11. Repeat steps 3-10 if necessary.
12. Select the
WAVEFORM button.
13. Set the motor speed to one fourth the speed found in
Step 5. Vary the motor speed
about this setting, and find the most resonant operating speed.
14. Change the current waveform using the left and right arrow keys or by using the
touch screen (if available). Adjust the current waveform for the smoothest operation.
15. Select the
OK button when you are finished matching the drive to the motor. By
selecting
OK, you will be storing the adjusted values in the parameter configuration
file.
Selecting the CANCEL button will return the adjusted values to the values
previously stored in the configuration file.
This completes the motor matching procedure.
