When your system has a resonance, it will have the following characteristic:
•
The system will emit a clear, high pitch (> 500 Hz). Do not confuse this problem with compliance, which has a
low pitch.
If the system performance is poor because of resonance, you can make the following corrections:
•
Reduce the bandwidth of the system.
•
Shorten the length and increase the diameter of shafts and lead screws.
5.5 EMPIRICAL METHOD: PHASING
NON-KOLLMORGEN MOTORS
This section discusses how to determine empirical phasing for non-Kollmorgen motors.
Section 4 discussed how to connect non-Kollmorgen motors in the section "Wiring Motor Leads for Other BLDC
Motors." That section is based on using sequences for either 60
°
or 120
°
commutation. However, if the
corresponding information for the motor is not available, use the following trial-and-error procedure.
During this procedure, ensure that the motor does not overheat. Depending on the motor, the specified analog-
command voltage may be too large. If the motor frame temperature exceeds 50
°
C, the command should probably be
reduced. If the motor is below 50
°
C, you should be able to comfortably rest your hand on it.
If your S/O has a velocity loop option, temporarily disconnect J6-3 and -4 from the velocity loop and directly apply
the command to those points.
Phasing by Trial and Error:
1. Install J2 if your motor uses 120
°
commutation. Remove J2 for 60
°
. Contact the motor manufacturer to
determine which is appropriate.
2. Put the amplifier in open-loop (install J5 in position "O").
3. Set ANALOG-CMD for 1.0 volt.
4. Connect the three hall sensor S1, S2, and S3 leads arbitrarily. (Power and Common must be connected
correctly.)
5. Enable the amplifier.
6. Try all six combinations of motor lead connections until the motor rotates freely. Always remove power
from the amplifier when changing motor lead connections.
Note some incorrect wiring combinations will cause the motor to rotate, but inefficiently and with zero-torque
positions (or "dead spots"). Carefully stop the motor by hand and feel torque as you let the motor rotate slowly. If the
wiring is correct, torque will be nearly continuous throughout the rotor rotation.
