Cause
The power of the encoder is out.
The data of the multi-turn counter of the
encoder exceeds the specified limit.
The encoder rotates faster than the
specified rate when it is battery-powered.
The encoder detects an error of the
single-turn counter.
The encoder detects an error of the multi-
turn counter.
The encoder detects an internal status error.
After the control power on, the encoder ro-
tates faster than the specified rate.
When an 11-wire encoder is used, Pr02 (con-
trol mode selection) is set to 7, 8 or 9 ("full-
close" control).
The control circuit operates incorrectly due
to large noises or any other reasons.
The driver's self-diagnosing function is acti-
vated, because an error happens in the driver.
Countermeasures
Check the voltage of the battery. Connect to
the battery, and then clear the encoder using
the absolute encoder clear mode contained
in the auxiliary function (see Details of Op-
eration in Appendix).
Limit the movable range to ?32767 revolu-
tions (15 bits) from the initial position. Adjust
the value of Pr0B.
Connect the power to the encoder and then
make sure that the encoder voltage is
5V?5%. Correct the SIG connections, if nec-
essary.
The motor may be broken. Replace the mo-
tor with a new one. Return the old motor to
the sales agent for repair.
Take measures to keep the motor away from rotating until
the driver outputs S-RDY.Take measures to keep the
motor away from rotating until the driver outputs S-RDY.
Set the value of Pr02 to 0, 1, 2, 3, 4 or 5.
Turn off the power and turn it on again. If the
error cannot be eliminated, the motor and/or
driver may be broken. Disconnect the power
supply of these equipment, and replace them
with new ones. Return the old equipment to
the sales agent for repair.
