The Allen-Bradley 1336-BDB-SP91D Adjustable Frequency Drive comes with sensorless vector control and is a member of Allen-Bradley’s 1336 Plus II Series of adjustable frequency drives. It uses Firmware versions 1-6 and its output is 0.5-600 HP (0.37-448 kW).

The 1336-BDB-SP91D is sensitive to ESD or Electrostatic Discharge. To avoid static damage during installation, testing, or maintenance, follow all applicable ESD control procedures.

Mount the 1336-BDB-SP91D with a clearance of at least 6 inches above and below it and a clearance of at least 4 inches on either side to ensure proper ventilation between it and other drives or devices. The 1336-BDB-SP91D can use IEC-BS88 and UL Class CC, T, RK1, or J fuses and IEC or UL circuit breakers. It can also use an RFI filter in environments where it is essential to have the lowest possible emissions.

Make sure that the 1336-BDB-SP91D’s discrete control and signal wiring are grounded at the equipment end at a single point that is not on the drive itself. If these wires are shielded, ground the shield at the same point as the wires. If these wires are short and grounded in a cabinet that does not contain any sensitive circuits, shielding for the wires is recommended but not necessary.
