Chapter 2: Installation 2.1.8 Handling Oil and Water Install a protective cover over the servomotor if it is used in a location that is subject to water or oil mist. Also use a servomotor with an oil seal when needed to seal the through-shaft section. Install the servomotor with the connector facing down. Through shaft section Note: Through sections of the shaft: This refers to the gap where the shaft protrudes from the end of the motor 2.1.9 Cable Stress Make sure that the power lines are free from bends and tension. Be especially careful to wire signal line cables so that they are not subject to stress because the core wires are very thin, measuring only 0.0079 to 0.012in (0.2 to 0.3mm). 2-6
Chapter 2: Installation 2.2 Servo Amplifiers The SGDH servo amplifiers are base-mounted servoamps. Incorrect installation will cause problems. Follow the installation instructions below. 2.2.1 Storage Conditions Store the servo amplifier within the following temperature range, as long as it is stored with the power cable disconnected. -20 to 85 C YASKAWA SERVOPACK SGDH- 200V MODE/SET CHARGE DATA/ POWER L1 L2 C N 3 L3 1 2 L1C L2C B1 B2 B3 U V C N 1 C N 2 W Sigma II series servo amplifier 2.2.2 Installation Site The following precautions apply to the installation site. Situation Installation in a Control Panel Installation Near a Heating Unit Installation Near a Source of Vibration Installation at a Site Exposed to Corrosive Gas Other Situations Installation Precaution Design the control panel size, unit layout, and cooling method so the temperature around the servo amplifier does not exceed 55 C. Minimize heat radiated from the heating unit as well as any temperature rise caused by natural convection so the temperature around the servo amplifier does not exceed 55 C. Install a vibration isolator beneath the servo amplifier to avoid subjecting it to vibration. Corrosive gas does not have an immediate effect on the servo amplifier, but will eventually cause electronic components and contactor-related devices to malfunction. Take appropriate action to avoid corrosive gas. Do not install the servo amplifier in hot and humid locations or locations subject to excessive dust or iron powder in the air. 2-7
Chapter 2: Installation 2.2.3 Orientation Install the servo amplifier perpendicular to the wall as shown in the figure. The servo amplifier must be oriented this way because it is designed to be cooled by natural convection or by a cooling fan. Secure the servo amplifier using the mounting holes. The number of holes varies (from two to four) with the frame size of the servo amplifier. Wall Ventilation 2-8
Chapter 2: Installation 2.2.4 Installation Follow the procedure below to install multiple servo amplifiers side by side in a control panel. Fan Fan 1.97in (50mm) minimum 1.18in (30mm) minimum 0.39in (10mm) 1.97in (50mm) minimum Servo Amplifier Orientation Install the servo amplifier perpendicular to the wall so the front panel containing connectors faces outward. Cooling As shown in the figure above, allow sufficient space around each servo amplifier for cooling by cooling fans or natural convection. Side-by-side Installation When installing servo amplifiers side by side as shown in the figure above, allow at least 0.39in (10mm) between and at least 1.97in (50mm) above and below each servo amplifier. Install cooling fans above the servo amplifiers to avoid excessive temperature rise and to maintain even temperature inside the control panel. Environmental Conditions in the Control Panel Ambient Temperature: 0 to 55 C Humidity: 90% r.h., or less Vibration: 0.5 G (4.9m/s 2 ) Condensation and Freezing: None Ambient Temperature for Long-term Reliability: 45 C maximum 2-9
