Safe‑Torque Off (STO) |
The Allen Bradley 1336F‑B020‑AN‑EN‑L6‑MX3 drive is made to give precise speed and torque control of AC motors. It works on 480 V three‑phase power and runs motors up to 20 HP. The drive uses V/Hz and closed‑loop vector control. This helps it keep speed even if load changes. It also has Safe‑Torque Off (STO) for safety. The STO stops torque fast if a fault happens or if a door opens. The drive has a built‑in keypad and LCD that shows status and lets users set parameters. It has PID loops for process control and can link to other devices via Ethernet/IP, DeviceNet, or Modbus.
The unit runs in temperatures from -10 °C to +50 °C. It fits in NEMA 1 or IP 20 panels. The housing resists dust and dirt. It has a heat sink and fan that keep it cool. The drive lets techs pick switching frequency from 2 kHz to 12 kHz. A higher frequency makes motor noise lower but draws more heat. A lower frequency cuts heat but may make motor hum. The drive draws about 28 A at full load. It meets UL, CE, and CSA safety rules. It also meets EMC standards for low interference.
Installation is simple. The drive has screw‑clamp terminals that hold wires tight. Each terminal is marked on the front. The built‑in keypad guides techs through setup with simple menus. It has plain words and numbers. It shows motor data, faults, and run status. Techs can upload or download settings via a memory card port. This helps when many drives need the same setup. The drive also logs trips with time stamps to help find faults fast. The metal case gives solid mounting points and cutouts for cables. It saves space and keeps panels neat.
🏭 Industry News
Variable speed drives are key to cutting energy use in factories. Recent studies show that fitting VFDs on pumps and fans can cut motor energy use by up to 30 %. Many steel, paper, and chemical plants now plan VFD upgrades in their next maintenance cycle. They aim to improve process control, cut wear on machines, and lower power bills. Drives with built‑in safety features like STO and advanced communications help plants meet stricter safety and environmental rules. The 1336 Plus II series stays in high demand as it balances cost, reliability, and features.
