b. Send the THALL command. It should report a number in the range
of 1–6, which indicates the phase wires are connected correctly. If
the response is
Ø or 7, a fault exists. Check the motor phase wiring
c. Send the
TPE command and turn the motor shaft. Verify the
encoder is counting in the correct direction. Turning the shaft
clockwise results in positive encoder counts when
CMDDIR is set
to zero (Ø). If not, check the encoder feedback wires and reset the
drive.
Hall Sensors
The troubleshooting procedures in this section assume that a terminal
emulator connection is established with the drive. The procedures assist you
in resolving a Hall fault (
ERROR bit E37-Bad Hall State). Several problems
can cause a Hall fault; the following checklist will help identify these
problems.
Troubleshooting Checklist
1. Does THALL report either 0 or 7?
If yes, see Problem 1 or 2, below.
2. Does
THALL change if you move the motor by hand?
If no, see Problem 2, below.
3. Does
THALL have six distinct Hall states from 1 to 6? (No numerical
order is necessary.)
If no, see Problem 2, below.
4. Does
THALL report the six distinct Hall states n times as the rotor turns
one revolution, where
n is equal to the number of pole-pairs (DPOLE)?
(Linear motors:
n = pitch)
If no, see Problem 2 or 3, below.
5. Does
THALL report the Hall state sequence [1, 5, 4, 6, 2, 3, 1...] as the
motor turns clockwise? (Clockwise means
TPE is increasing when
CMDIR set to zero (Ø); it is also the direction the motor turns in
DMODE1.)
If no, see Problem 4, below.
6. Does
ERROR report a Hall fault each time the drive is enabled
(
DRIVE1), even though the Hall state sequence is correct?
If yes, see Problem 4, below.
7. Does the Hall fault occur irregularly?
If yes, see Problem 6, below.
Possible Problems
1. No Hall states are seen by the drive.
2. The cable is not connected, or is connected incorrectly (incorrectly
wired).
3.
DPOLE or DMEPIT is not set correctly.
4. Either the motor wires or the Hall wires are connected incorrectly.
Use Procedure 1 to fix this problem by changing the motor wires.
Use Procedure 2 to fix this problem by changing the Hall wires.
5. The Hall wires or the encoder wires may have loose connections,
causing intermittent faults.
