The Okuma VAC5-D11 is an upgraded servo drive in the VAC5 series, designed for industrial applications requiring motor control. This model features an optical interface and employs fiber optic cable for NC communication. Its front-panel seven-segment LED display shows operation and error status, with the ability to identify alarm causes through displayed error numbers. On units with firmware VAC4113 or subsequent versions, both the control and winding status can be shown in normal operation mode. The firmware version can be found on the CPU board stickers, accessible by removing the front cover. Components include a power board, a CPU board, and a GD board. Weighing 20kg, the drive's approximated dimensions are 450 x 310 x 254 millimeters. It requires three-phase 220 Volts AC input and the output depends on the power capacity of the input supply. It can deliver either 11 or 15 kilowatts, based on a 16 or 22 kVA power supply, respectively. The operating ambient temperature range is 0 to 55 degrees Celsius.
