Description
Error Message
Corrective Action
(4) Check if the motor power cable is too old.
16
The equivalent current that
the servo drive outputs
exceeds the maximum
continuous current of motor.
Soft-thermal
threshold
reached
(1) Check if the continuous current and
instantaneous current for the motor is within its
specification.
(2) Check if the acceleration command of path
planning is greater than the rating of the motor.
(3) Check if the motor is obstructed during motion.
(4) Reset the servo drive and enable the motor
again.
(5) Check if the motor model and its current
parameter is correctly set.
17
PC cannot communicate with
the servo drive.
-
(1) Check if the driver for RS232 to USB converter is
installed. Check if RS232 communication port
appears in the device manager of Windows
operating system.
(2) Check if transmission rate (BPS) and
communication port (Port) are correctly set. Refer
to section 5.1.
(3) Check if the pin assignment of RS232 cable is
correct. Refer to section 4.6.
18
In position mode, the servo
drive cannot receive the
single-ended pulse signal
sent from controller.
-
Check the output type of controller. It it is single-ended
output (For example, Mitsubishi PLC module QD75P),
ensure group D in I/O center is set as pull up. Refer to
sections 4.7.3 and 5.4.1.
19
Controller receives incorrect
position information while
using emulated encoder
function.
-
While saving parameters ( ) to the servo drive Flash,
the emulated encoder function is not available.
Therefore, the position information sent to the
controller during this time could be incorrect.
20
Fail to enable or disable
digital output (O1 to O4) in
PDL program.
-
Check if the digital output is set to “PDL usage” in I/O
center.
21
Error “Hall sensor error”
occurs while using digital Hall
sensor.
Hall Sensor
Error
Open Quick view or Scope in Lightening to observe
physical quantity “46 digital hall bits”. Move the motor
manually to see if the value of this physical quantity
changes. If the value does not change, check if the
encoder cable is correctly connected. If the encoder
cable is correctly connected, please replace it with
another encoder cable. If the above method does not
work, please replace the servo drive.
If the above methods cannot clear this error, the digital
Hall sensor could be broken, please replace the digital
Hall sensor.
