Description
Error Message
Corrective Action
10
The signal of position
feedback sensor (reader) is
abnormal.
Encoder error
(1) While using Renishaw optical position feedback
system, check if the LED on the reader lights up.
Normally, the LED should be green. If the LED
does not light up, check if 5 V power is supplied
or the signal cable is properly connected and is
not short-circuited. If the LED is red, adjust the
gap between the reader and scale and check if
the scale is clean.
(2) While using HIWIN magnetic scale, ensure the
gap between the reader and scale is between 0.1
to 0.2 mm. Check if the signal cable is properly
connected and is not short-circuited. Keep the
scale away from strong magnet.
(3) Check the reader is digital type or analog type.
Ensure its model and resolution are correctly set.
(4) Check if the phase sequence (A/B phase) of
digital reader is incorrect.
(5) When analog reader is not moving, check if the
sinusoidal signal of the analog reader is too
weak.
(6) Check if the servo drive and machine are
grounded, and the shield is grounded.
11
Motor (forcer) is overheating.
Motor over
temperature
sensor activated
(1) Check if the over temperature cable is
connected.
(2) Check if the temperature of the motor is too high.
(3) Check if the continuous current and
instantaneous current of the motor are within its
specification.
(4) Check if the duty cycle of the motor is too high.
12
DC bus voltage is too small.
Under voltage
detected
(1) Check if the servo drive is connected to AC main
power 100 or 240 Vac.
(2) Use multimeter to check if AC main power 100 or
240 Vac is supplied.
13
DC bus voltage is too large.
Over voltage
detected
(1) Check if the velocity, acceleration and load are
within the specifications of the servo drive and
motor.
(2) If the motor needs to move at high speed,
consider installing regenerative resistor. Select
regenerative resistor based on your load and
motion conditions.
(3) Check if the load is too heavy.
(4) Check if the speed is too high.
14
Position error is greater than
the value set for maximum
pos error.
Position error too
big
(1) Check if the common gain (CG) is too small.
(2) Open Protection tab in Application center and
check if the value set in the field of maximum
pos error is too small.
(3) Check if the motor is obstructed during motion.
(4) Check if the reader is normal.
(5) Check if the optical scale is clean.
(6) Check if the load is too heavy.
(7) Check if the guideway has not been maintained
for a long period of time.
(8) Check if the cable tray is too tight.
15
There is short circuit among
the U, V and W wires.
Motor short (over
current) detected
(1) Ensure there is no short circuit among the U, V
and W wires and the wiring is ideal.
(2) Ensure there is no short circuit among the U, V
and W wires and ground.
(3) Ensure the resistances of U, V and W wires are
the same.
