2.3 ABOUT THE SCA06
The servo drive SCA06 is a high-performance product which allows controlling the speed, torque and position
of three-phase, sine-wave, alternate current servomotors. The main characteristic of this product is the high
performance and high precision of movement control of the servomotor shaft due to the operation in closed loop
by means of the position feedback given by a sensor inside the servomotor.
The SCA06 features independent control and power supply, allowing, for instance, that the product communication
networks keep on working normally even if the power circuit must be turned off for some reason.
The use of braking resistors provides greatly reduced braking times, optimizing the processes that require high
performance.
Several special functions are available, such as programming in ladder with positioning blocks, which provides
extreme flexibility and integration to the drive.
The SCA06 can be used in different applications with many options of cables, both for simple applications and
complex applications like handling, environments with oil, etc.

2.6 RECEIVING AND STORAGE
The SCA06 is supplied packed in a cardboard box. In the external part of this package, there is an identification
label identical to the one attached to the side of the SCA06.
At the receipt of the product, check:
If the identification label of the SCA06 corresponds to the purchased model.
Any damages occurred during transportation.
Report any damages immediately to the carrier.
If the SCA06 is not installed soon, store it in a clean and dry location (temperature between -25 °C (-13 °F) and
60 °C (140 °F)), with a cover to prevent dust accumulation inside it.
ATTENTION!
When the inverter is stored for long periods, it becomes necessary to perform the capacitor reforming.
Refer to the procedure in Table 7.2 on page 7-5.

3 INSTALLATION AND CONNECTION
This chapter describes the electric and mechanical installation procedure of the SCA06. The directions and
suggestions must be observed so as to ensure the safety of people, equipment and proper operation of the
servo drive.
3.1 MECHANICAL INSTALLATION
3.1.1 Environmental Conditions
Avoid:
Direct exposure to sunlight, rain, high humidity or sea-air.
Inflammable or corrosive liquids or gases.
Excessive vibration.
Dust, metallic particles or oil mist.
Environment conditions permitted for the operation of the inverter:
Ambient temperature: 0 ºC (32 °F) to 50 ºC (122 °F) - rated conditions (measured around the servo drive).
From 50 ºC (122 °F) to 60 ºC(140 °F) - 2 % of current derating for each Celsius degree above 50 ºC (122°F).
Air relative humidity: 5 % to 90 % non-condensing.
Maximum altitude: up to 1000 m (3280 ft)- rated conditions.
1000 m (3280 ft) to 4000 m (13123 ft) - 1 % of current derating for each 100 m (328 ft) above 1000 m (3280 ft)
of altitude.
Pollution degree: 2 (according to EN50178 and UL508C), with non-conductive pollution. Condensation must
not originate conduction through the accumulated residues.
3.1. 2 Positioning and Mounting
Check the weight of the servo drive in Table 9.1 on page 9-1 or in the product label.
Install the servo drive in the vertical position on a flat surface, preferably on a galvanized and grounded plate.
Check the external dimensions and position of the fixation holes in Figure 3.1 on page 3-3. For further details,
refer to section 9.3 MECHANICAL DATA on page 9-4.
Put the first bolt on the surface where the servo drive will be installed, install the servo drive and then tighten the bolt.
Allow the minimum clearances indicated in Figure 3.2 on page 3-5 so as to allow the cooling air circulation.
It is possible to mount the servo drives side by side without side clearances.
Do not put sensitive component parts right above the servo drive.
ATTENTION!
When one servo drive is installed above another, use the minimum distance B1 + C1 (Figure 3.2 on
page 3-5) and deviate the hot air coming from the servo drive below from the one mounted above.

3
Installation and Connection
3-2 | SCA06
If the mounting is inside a panel, provide proper ventilation so that the internal temperature remains within the
allowed range for the operating conditions of the servo drive.
The power dissipated by the servo drive at rated condition is specified in Table 9.1 on page 9-1.
ATTENTION!
Provide independent conduits or gutters for the physical separation of signal, control, and power
cables (refer to section 3.2 ELECTRICAL INSTALLATION on page 3-6).
