Braking resistor is
overheated or
overloaded
1. When the braking resistor
is selected as the internal
braking resistor, it means
over temperature;
2. When the braking resistor
is externally connected, it
means overload.
A-83
1. Please confirm whether the load
inertia is too large;
2. Please confirm whether it starts
and stops frequently, and whether
the speed is too high;
3. Please check whether the actual
resistance value is greater than the
set value.

needs to be
powered on
again
Modified the parameters
that need to be re-powered
on to take effect
A-84
Re-power on or clear the alarm to
make the alarm disappear.

Receive position
pulse when servo
is OFF
Servo received pulse
instruction in non-SON state
or non-position mode
A-85
Please check the control signal timing
of the host device, the servo is
stopped or the pulse is still being sent
in the non-position mode.

Input pulse
frequency is too
high
The equivalent speed of the
input frequency of the
instruction pulse is too large
A-86
Check whether the setting of the
pulse input frequency and the
instruction pulse number of one turn
of the motor (P0-15) or the electronic
gear ratio (P0-16~P0-19) is
reasonable.

Main circuit
momentary
power off
The main circuit input
voltage is momentarily too
low
A-88
Check whether the mains input has
voltage, and then power on again or
clear the alarm; if the mains is normal
and the alarm still exists, please
contact the manufacturer.

Duplicate DI port
configuration
Different DI ports are set to
the same function
A-89
Check the function code "DIDO
configuration" to check the DI
channel function selection: DI_1
channel function selection (P6-02) ~
DI_4 channel function selection
(P6-11), and check whether the 4 DI
channel function selections are
duplicated. If there are unnecessary
channels set to be closed, power off
and then power on again.

the same function
A-90
Check the function code "DIDO
configuration" to check the DI
channel function selection: DI_1
channel function selection (P6-02) ~
DI_4 channel function selection
(P6-11), and check whether the 4 DI
channel function selections are
duplicated. If there are unnecessary
channels set to be closed, power off
and then power on again.

Parameter
modification is
too frequent
The frequency of
communication to modify
function code parameters is
too frequent
A-91
Confirm whether the host computer
writes parameters frequently, and
modify the corresponding parameter
writing method
