:Auto detection of motor parameters is in error
Causes Checking Method Corrective Actions
When executing the
function of PM-01, if
the friction is too big,
motor is stuck or
entering wrong
resolution and pitch
pole, this alarm will
occur.
1. Check if motor pole pitch,
encoder resolution and
encoder type are entered
correctly.
2. Check if motor is stuck during
detection.
3. Check if the motor friction is
too big.
4. Check if the feedback of linear
scale is abnormal, the
connection is breakdown, the
scale is not installed properly
or there is noise interference.
1. Enter the value which is the
same as the actual one and
activate the detection again.
2. The rotary motor will rotate at
forward and reverse direction
for one magnetic cycle during
detection. The linear motor
will move for a pitch forward
and backward. Please
preserve the moving distance
before detection.
3. Chang another motor with
more power.
4. Correct the problem of linear
scale.
:Initial magnetic pole detection error
Causes Checking Method Corrective Actions
When motor does not
connect to Hall sensor,
it will search the initial
magnetic pole when
power on. If the initial
magnetic pole is not
found, this alarm will
occur.
1. Check if the feedback is
normal
2. Check if the motor friction is
too big
Correct the problem of the
encoder
:Motor parameter is not confirmed
Causes Checking Method Corrective Actions
If PM-02 = 0, this alarm
occurs when motor
servo On.
Make sure the motor parameter
group is entered correctly. Set
PM-02 to 1 and re-power on will
do. After the detection procedure
is completed, this parameter will
be setup automatically.
