9
The servo drive is overheating.
Amplifier over
temperature
(1) Check if the servo drive is installed in
well-ventilated location.
(2) Check if the ambient temperature is too high.
(3) Wait till the servo drive cools down.
(4) If the servo drive has been used
for a long
period of time, check if heat sink is needed.
10
The signal of position feedback
sensor (reader) is abnormal.
Encoder error
(1) When using Renishaw optical position
feedback system, ch
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
properly connected and is not short-circuited.
If the LED is red, adjust the gap between the
read
er and scale and check if the scale is
clean.
(2) When 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 the analog reader is not moving, check
if the sine wave signal of analog reader is too
small.
(6) Check if the servo
grounded, and the shield is grounded.
11
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 240 Vac.
(2) Use multimeter to check if AC main power 240
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 according to your load
and motion conditions.
(3) Check if the load is too heavy.
(4) Check if the speed is too high.
