 Safety Precautions
 
Carefully note and observe the following safety precautions when receiving, inspecting, installing, operating, maintaining and 
troubleshooting. The following words, DANGER, WARNING and STOP are used to mark safety precautions when using the Delta’s servo 
product. Failure to observe these precautions may void the warranty! 
ASDA-A2 series drives are high-resolution, open type servo drives and must be installed in an NEMA enclosure such as a protection control 
panel during operation to comply with the requirements of the international safety standards. They are provided with precise feedback 
control and high-speed calculation function incorporating DSP (Digital Signal Processor) technology, and intended to drive three-phase 
permanent magnet synchronous motors (PMSM) to achieve precise positioning by means of accurate current output generated by IGBT 
(Insulated Gate Bipolar Transistor). 
ASDA-A2 series drives can be used in industrial applications and for installation in an end-use enclosure that do not exceed the 
specifications defined in the ASDA-A2 series user manual (Drives, cables and motors are for use in a suitable enclosure with a minimum of 
a UL50 type 1 or NEMA 250 Type 1 rating). 
Unpacking Check 
 
Please ensure that both the servo drive and motor are correctly matched for size (power rating). Failure to observe this 
precaution may cause fire, seriously damage the drive / motor or cause personal injury. 
Installation 
 
Do not install the product in a location that is outside the stated specification for the drive and motor. Failure to observe 
this caution may result in electric shock, fire, or personal injury. 
Wiring 
 
Connect the ground terminals to a class-3 ground (Ground resistance should not exceed 100Ω). Improper grounding may 
result in electric shock or fire. 
 
Do not connect any power supplies to the U, V, W terminals. Failure to observe this precaution may result in serious 
injury, damage to the drive or fire. 
 
Ensure that all screws, connectors and wire terminations are secure on the power supply, servo drive and motor. Failure 
to observe this caution may result in damage, fire or personal injury. 
 
In order to prevent fire hazard and accidents, please form the wiring by following the cable specifications outlined in this 
quick start.   
Operation 
 
Before starting operation with a mechanical system connected, change the drive parameters to match the user-defined 
parameters of the mechanical system. Starting the operation without matching the correct parameters may result in servo 
drive or motor damage, or damage to the mechanical system. 
 
Ensure that the emergency stop equipment or device is connected and working correctly before operating the motor that 
is connected to a mechanical system. 
 
 
 
Do not approach or touch any rotating parts (e.g. shaft) while the motor is running. Failure to observe this precaution may 
cause serious personal injury. 
 
 
In order to prevent accidents, the initial trial run for servo motor should be conducted under no load conditions (separate 
the motor from its couplings and belts). 
 
For the initial trial run, do not operate the servo motor while it is connected to its mechanical system. Connecting the 
motor to its mechanical system may cause damage or result in personal injury during the trail run. Connect the servo 
motor once it has successfully completed a trail run. 
 
Caution: Please perform trial run without load first and then perform trial run with load connected. After the servo motor is 
running normally and regularly without load, then run servo motor with load connected. Ensure to perform trial run in this 
order to prevent unnecessary danger. 
 
Do not touch either the drive heat sink or the motor during operation as they may become hot and personal injury may 
result. 
Maintenance and Inspection 
 
 
Do not touch any internal or exposed parts of servo drive and servo motor as electrical shock may result. 
 
Do not remove the operation panel while the drive is connected to an electrical power source otherwise electrical shock 
may result. 
 
Wait at least 10 minutes after power has been removed before touching any drive or motor terminals or performing any 
wiring and/or inspection as an electrical charge may still remain in the servo drive and servo motor with hazardous 
voltages even after power has been removed. 
 
Do not disassemble the servo drive or motor as electric shock may result. 
 
Do not connect or disconnect wires or connectors while power is applied to the drive and motor. 
 
Only qualified personnel who have electrical knowledge should conduct maintenance and inspection. 
 
Ensure that the “Charge” indicator ceases when performing any maintenance, inspection or repairing. 
Main Circuit Wiring   
 
Install the encoder cables in a separate conduit from the motor power cables to avoid signal noise. Separate the conduits 
by 30cm (11.8inches) above. 
 
Use multi-stranded twisted-pair wires or multi-core shielded-pair wires for signal, encoder (PG) feedback cables. The 
maximum length of command input cable is 3m (9.84ft.) and the maximum length of encoder (PG) feedback cables is 
20m (65.62ft.). 
 
 
As a charge may still remain in the drive with hazardous voltages even after power has been removed, be sure to wait at 
least 10 minutes after power has been removed before performing any wiring and/or inspection. 
 
 
 
It is not recommended to frequently power the drive on and off. Do not turn the drive off and on more than once per 
minute as high charging currents within the internal capacitors may cause damage. 
Main Circuit Terminal Wiring 
 
Please perform the wiring after the terminal blocks are all removed from the drive. 
 
Insert only one wire into one terminal on the terminal block. 
 
When inserting wires, please ensure that the conductors are not shorted to adjacent terminals or wires. 
 
Ensure to double check the wiring before applying power to the drive.
