Safety notification
Indicates an error in use, it will leads to hazardous conditions and result in death or serious
injury.
Dangerous

While the motor is running, please do not touch the rotating parts.If not,it will lead to
injury.
When installed on the machine running, please put the motor may at any time in
advance the state of emergency stop. Otherwise it will lead to injuries, mechanical
damage.
Please don't touch the servo unit inside. Otherwise it will cause electric shock.
In an energized state, please make sure it install the power supply terminal block
cover. Doing so may cause an electric shock.
After the power is turned off or withstand voltage test, during running lights, do not
touch the power terminals. Otherwise they will be residual voltage caused by electric
shock.

Servo motor installed in the machinery of the state,.if there is an error, it will not
only cause the mechanical damage, sometimes it may result in personal injury
accidents.
Except for special purposes, it is not necessary to change multi-turn limit on the
number of turns. If you accidentally changed the data,it will be dangerous.
When more inconsistent rotation laps limit alarm, please be sure to first make sure
the parameters of the servo unit is correct.
If it is under the parameter value error condition for multi-turn limit on laps, it will
set the value of the error to the encoder. Although can remove alarm,due to detect the
location of the deviation is very big, it cause mechanical moved to the location of the
unexpected, and very dangerous.

3.3 Braking resistor
Function : Discharge, to ensure the stability of the DC bus voltage. In servo motor control, the
back EMF generated by the motor is feed back to the bus capacitor, causing the bus voltage to rise.
When the voltage reaches the alarm limit (P0-14), the servo output alarm EN-03
Therefore, to ensure that the bus voltage does not exceed the voltage limit of device, the system
will conduct the discharge terminal when the voltage rises to the limit, and quickly balance the bus
voltage through the brake resistor.

3.4 Brake wiring
In a vertical mechanism, when power off or the servo is enable OFF, the workpiece will fall due to
gravity.So we need to use the servo motor with brake to avoid it’s slide down
Parameter setting:P5-24 set 0084;P5-26 set 0000;then power off the driver and restart.If the
workpiece is slightly down when enable OFF, increase P5-06 around 100ms or decrease the value
of P5-08, and fine tune according to the situation; when the speed is lower than the setting value
of P5-07, the brake is on.

1. Turn off the enable signal first.（External enable: Please disconnect the external signal;
Internal power-on enable: set P0-01 to n.0101 and then power off and restart）
2. Enter F4-00
（Refer to e in section 4.2）
3. Check the motor parameters (take the drive SC1-3010/AMS80-02430Z as an
example)
a) Check motor code power code F0-00 :display 750 means 750W
b) Check motor model code F0-24: shows 02430 indicates 2.4N·M, 3000 rpm
c) Check input voltage level and flange F0-25:display 2080 indicates 220V, 80
flange
If the alarm is EN-02, also need current check, please refer to section 4.6

20
4.6 Current check
Function: Eliminate motor control instability or abnormal noise caused by inaccurate current
sampling,whcih caused by hardware drift
Method：
Turn off the enable signal first.
(External enable: Please disconnect the external signal; Internal power-on enable: set
P0-01 to n.0101 and then power off and restart)
Setting parameters
(Setting P0-00 to 2; P0-01 to 0)
Enter F6-00 to set the enable signal
(In the bb state, press the STA button shortly, when F0-00 appears, press INC, then
F6-00 appears, press shift to 0 to flash, press Ent to display E-, then press shift again
to display E-n drive enable; Wait 10 seconds to complete the verification, press DEC
to cancel the enable)
Chapter 5 Trial and tunning steps
5.1 No-load detection
To avoid damage the servo driver or mechanism, first remove the load connected to the servo
motor (including the coupler and other accessories).Then doing testing according to normal
operating procedures.After testing is OK,can connect with load.
Test items：
Pre-boot detection
(cut off the power supply)
Ensure that the servo driver and motor have no mechanical
damage
Ensure that the terminal wiring is secure and there is no danger
of electric shock
Ensure that the wiring is complete and correct
Ensure that the external input signal meets the standard
Guarantee no other errors or dangers
Running time detection
(power on)
Ensure that the wires are not pulled or abrasion during operation
Does the motor have strong shake or abnormal sound?
Does the indicator light normal?
Is there any alarm display? If there is an alarm, please first find
the alarm code in the alarm parameter table, and then clear the
alarm after eliminating the alarm factor.
When modifying parameters, please confirm the parameter
modification and effective time.
Check if the device execute according to preset modes and
parameters
