Air Flow Measuring Points
When operating the servo drive, the ambient environmental temperature should be between 0°C (32°F) and 55°C (131°F). If
the temperature is over 45°C (113°F), place the product in a well-ventilated environment. During long-term operation, the
suggested temperature of the operating environment should be under 45°C (113°F) to ensure the servo drive’ s
performance. For SV2A-2040, keep a clearance of at least 50mm above the drives and keep the speed of air flow above 0.5
m/s. For SV2A-2075,
SV2A-2150, SV2A-2200, SV2A-2300, SV2A-2550, SV2A-2750, and SV2A-2F00, keep a clearance
of at least 50mm above the drives and keep the speed of air flow above 1 m/s. If the product is installed in an electrical
cabinet, make sure the size of the cabinet and its ventilation condition can prevent the internal electrical devices from
overheating. Also, check if the vibration of the machine affects the electrical devices in the electrical cabinet.
La température ambiante de l’environnement de fonctionnement de l’entraînement asservi doit être entre 0 °C (32 °F) et
55 °C (131 °F). Si la température est supérieure à 45 °C (113 °F), placez le produit dans un environnement bien ventilé.
Pour le fonctionnement à long terme, la température suggérée de l’environnement d’opération doit être inférieure à 45 °C
(113 °F) afin d’assurer le bon rendement de l’entraînement asservi. Si le produit est installé dans un tableau de distribution,
assurez-vous que la taille du tableau de distribution et la ventilation peuvent empêcher la surchauffe des dispositifs
électriques internes. Vérifiez également si la vibration de la machine affecte les dispositifs électriques du tableau de
distribution.
(5) Installation direction and space
Precautions:
◼
Incorrect installation direction may result in malfunction.
◼
For better ventilation and cooling, allow sufficient clearance space between the AC servo drive and the adjacent
objects and the wall, or overheating may result in malfunction of the machine.
◼
Do not block the ventilation holes of the AC servo drive, and do not mount it in the incorrect direction, or it may
result in malfunction of the machine.

Orientation et espace requis pour l’installation
Precautions:
◼
Une mauvaise orientation d’installation peut entraîner un dysfonctionnement.
◼
Pour une meilleure ventilation et un meilleur refroidissement, prévoyez un dégagement suffisant entre
l’entraînement asservi c.a., les objets adjacents et le mur, sinon la surchauffe peut entraîner un
dysfonctionnement de la machine.
◼
Ne bloquez pas les orifices d’aération de l’entraînement asservi c.a. et ne le fixez pas dans la mauvaise direction,
ou cela pourrait entraîner un dysfonctionnement de la machine.

(6) Basic inspection
Item
Description
General inspection
◼
Periodically check to confirm the screws are securely tightened. This includes the screws in
the servo drive, the connection screws between the motor shaft and machine, and the
connection screws between the terminal block and machine.
◼
Prevent oil, water, metallic particles, and other foreign matter from entering the control box or
ventilation equipment. Protect the servo drive from any drill cuttings.
◼
If the control box is installed in a location where dust or harmful gas are present, ensure the
dust or harmful gas cannot enter the control box.
◼
Make sure to wire encoders and other devices in the proper sequence to avoid sudden
unintended acceleration or damage to the motor.
Inspection before
operation
(power is not
applied)
◼
To avoid electric shock, connect the ground terminal of the servo drive to the ground terminal
of the control box. If wiring must be added or modified, wait at least 10 minutes after
disconnecting the servo drive from the power supply or discharge the electricity with a
discharge device.
◼
Isolate the wires at the wiring terminal.
◼
Make sure the wiring is correct to avoid damage or any abnormal operation.
◼
Check for and remove any electrically conductive objects, including metal sheet and screws,
or flammable objects inside or near the servo drive.
◼
Make sure the STO circuit is OFF.
◼
To ensure the electromagnetic brake works, make sure the stop and circuit breaker functions
are working properly.
◼
Reduce the electromagnetic interference if there is electromagnetic interference with the
peripheral devices.
◼
Make sure the external voltage level of the servo drive is correct.
Inspection before
operation
(power is applied)
◼
The encoder cable should be protected from excessive stress – make sure the cable is not
worn or stretched.
◼
Contact AutomationDirect if the servo motor vibrates or makes unusual noise during operation.
◼
Make sure the parameter settings are correct. Different machines have different
characteristics. Adjust the parameters according to the characteristics of each machine.
◼
Reset the parameters when the servo drive is in the Servo Off status to avoid possible
malfunction.
◼
If there is no contact noise or other abnormal noise when the relay is operating, contact
AutomationDirect
◼
Contact AutomationDirect if the power indicator or LED display does not function properly.

Inputs SIGN (36) and PULSE (43) are
designed for Line Driver (differential)
signals. Do not use with 24V. For 5V
open collector applications, see
section 3.5 in the User Manual.
Note: *1. For 200-230VAC single-phase input or 100-120VAC single-phase input (≤ 2kW), use R and S.
*2. To use external regen resistors: Connect resistors across terminals P3 and C and remove jumper between P3
and D.
To use the internal regen resistor (≤ 3kW): Jumper terminals P3 and D.
(Drives > 3kW do not have an internal regen resistor.)
*3. The brake coil has no polarity. (BRKR = DO code 08 and OVRD = DI code 21)
(see the other diagrams for clearance dimensions)
