Technical data of product parameters

Several problems can occur with encoder-based systems. The
most common problem is miswiring. The section on system phasing
(above), provides the necessary troubleshooting information.
Miswired Hall channels can cause intermittent problems. With
miswired Hall channels, the motor operates correctly sometimes,
but occasionally does not operate correctly after cycling power. It is
very important to physically verify the Hall effect channels. There isQHMV306command in the SERVOSTAR manual called, “HALLS.” It returns
the hall code as “read.” It is important that the installation and
startup procedures for the machine sequence the motors throughQHMV306the appropriate hall codes to make sure they are present and in
the right sequence.
An ‘illegal hall code’ error occurs if the Hall channels go to all low or high conditions. A broken wire or misphased channel can cause
this problem.
It is important that the A and the B channels be wired appropriately
to the SERVOSTAR drive to ascertain the correct directional drive This can be verified using PFB while rotating the motorlockwise. PFB should be counting in a more positive
direction. If it counts in a negative direction, the A and B channels
are inverted. To fix this, either swap the A and /A wires from the
encoder or use MFDIR.
A/B Line Break errors may occur and can be misleading. The
SERVOSTAR receives the A/B/I channels in a differential format.
Each channel is fed into a bridge rectifier to create a DC voltage
that is monitored for presence. Absence of any one of these three
voltages (except the I channel in MENCTYPE 3, MENCTYPE 4,
and MENCTYPE 6) cause an A/B line break fault.
