5.10.3: Guidelines for Choosing Auto Phase Current and Increment Rate
Values
Here are some considerations in choosing Auto Phase Current and Increment Rate values:
• If friction is high, then more current may be required to move the load.
• High static friction may require more current to overcome stiction.
• Transition from static friction to dynamic friction, and back, may produce jerky motion.
• A faster rate will operate in the dynamic friction range.
• A slower rate will operate in the static friction range.
• If the friction is low, as in the case of air bearings, low frequency oscillations may occur; thus,
less current and slower rates may be required. If oscillations persist, then friction may need to
be temporarily added.
5.10.4: Trouble Shoot Motor Direction Setup
If motor direction setup step failed:
5.10.4.1 Check Encoder or resolver power and signals.
5.10.4.2 Verify that the encoder is differential. (Contact factory if encoder is single-ended.)
5.10.4.3 Check shielding for proper grounding.
5.10.5: Trouble Shoot Motor Wiring Setup
If motor wiring setup step failed:
5.10.5.1 Verify that amplifier is disabled.
5.10.5.2 Check for mechanical jamming.
5.10.5.3 Check for smooth motion with no mechanical jerking.
5.10.5.4 Check for good connections to the motor power wires.
5.10.5.5 Disconnect motor power wires.
5.10.5.6 Measure for proper motor resistance.
5.10.6: Trouble Shoot Halls Wiring Setup
If Halls wiring setup step failed:
5.10.6.1 Check Halls power and signals.
5.10.6.2 Check for smooth motion with no mechanical jerking.
5.10.6.3 Check shielding for proper grounding.
5.10.7: Other Problems
If the auto phase procedure fails despite these corrective measures, see
Manual Phasing (p. 145).
