9101-1921

The 9101-1921 (2098-DSD-005X-DN) Digital Servo Drive with Indexing and DeviceNet Interface is a 500W servo drive by Allen-Bradley used for control of industrial-based servo motors. The drive has an AC single-phase rating of 100-240V AC and 9A input current at 47-63Hz, and a maximum inrush current of 100A at 230V AC. It supplies 15A of intermittent output current and provides 500W output power with a 38J absorption capability. The 9101-1921 has an internal capacitance of 1410μF and provides 400V DC BUS voltage protection. It has 8 digital inputs and 4 digital outputs which are isolated and a Normally-Open 30V DC 1A relay output. It has 1 analog ±10V, 8 bits 2mA output and 2 analog (ILIMIT and COMMAND) inputs. The drive communicates serially with external devices connected through the RS-232/RS-422/RS-485 port using the CN3 serial port connector. It also communicates using the DeviceNet communication interface with 125, 250, 500 kps, and auto-baud selectable baud rates with 00-63 redistribution points (nodes). The 9101-1921 has an operational power dissipation of 48W and the entire drive circuitry is fused with the 230V AC Class J and Class CC Bussman fuse. It provides control and positioning through the digital PID with feed-forward control and update rates of 250μs and 1ms. It has 4 motor feedback encoders with a hall sensor transducer and a 100 kHz (Sine/Cosine Input) 2.5 MHz (TTL Input) encoder input frequencies. The 9101-1921 is built to withstand an operational shock of 15G and a vibration of 2.5G at 10-200Hz and it can function without de-rating at an altitude of 1500m (4921.5ft). it has an operating temperature range of 0-55° C at 5-95% non-condensing relative humidity and it is stored at a non-operating temperature range of -40-70° C. The 9101-1921 weighs approximately 1.8kg and has approximate dimensions of 98.1mm x 32.77mm x 65.02mm.
