SDV3- E Series servo system
Quick manual

1. Safety precautions
DANGER
● Never connect wires while power on. Do not check components or signal for circuit board During operation.
● Do not dismantle or change servo motor drive wire, circuit or components.
● Make sure grounding terminals are correctly grounded.
CAUTION
● Do not perform a withstand voltage test for components of servo motor drive, it can cause semi-conductor
components to be damaged by high voltage.
● Never connect the output terminals U, V, W to AC power.
● CMOS IC on control circuit of the servo motor drive shall be damaged by electrostatic influence. Do not touch
main circuit board.
● Connect the output terminals U、V、W with wiring terminals U、V、W respectively, otherwise, it may cause
damage to the equipment due to the racing of the servo motor and injuries.
2. Products receiving
All products have been performed with strict test and inspection. After receiving the servo motor drive, the
following checks shall be performed.
●To check that SAVCH servo motor drive, an instruction manual is inside of the package.
●To check whether model number correspond with model and capacity your purchase order.
●To check whether there are damaged parts during transportation and deliver. If there are, do not connect with
power.
If any of the above checkpoints are not satisfactory, contact your SAVCH ELECTRIC representative for a quick
resolution.

Installation Notes:
1.Check the L1,L2 power and connecting wire.
2.Check the servo motor output U, V, W terminal phase wires (Unable to run when the connection is wrong).
3.External connected regeneration resistor is the selective spare, adopt according to the actual needs.
4.CHARGE indicator is on means that the power is on. When the Power is turned off, there is still left with electric
in the main-circuit, so the cable should be removed only when all the indicators are off.
