Q1: What is the primary function of the 20G1AND156JA0NNNNN?
It is a PowerFlex 755 adjustable frequency AC drive used to control the speed and torque of three-phase AC motors. It is designed for high-performance applications requiring precise motor control, embedded EtherNet/IP connectivity, and flexible option card expansion .
Q2: Does this drive include a Human Interface Module (HIM)?
No. The model number includes "Blank (No HIM)", meaning it ships with a blank cover instead of an operator interface . For local programming and monitoring, a compatible HIM (such as 20-HIM-A6 for drive-mounted or 20-HIM-C6S for door-mounted) must be ordered separately .
Q3: What communication protocols does this drive support?
The drive features embedded EtherNet/IP as standard, enabling seamless integration with Allen-Bradley PLCs and Studio 5000 Add-On Profiles . Additional communication protocols (DeviceNet, ControlNet, PROFIBUS, etc.) are available via optional 20-750 series communication modules. A Dual-Port EtherNet/IP Option Module supports ring, linear, and star topologies, as well as Device Level Ring (DLR) for fault-tolerant connectivity .
Q4: What is the difference between Normal Duty and Heavy Duty ratings?
Normal Duty (ND) is for applications with relatively constant loads (e.g., pumps, fans), rated at 125 HP / 90 kW. Heavy Duty (HD) is for applications with high starting torque or frequent starts/stops (e.g., conveyors, mixers), rated at 100 HP . Choose the rating based on your motor's most demanding operating conditions.
Q5: Is the 20G1AND156JA0NNNNN still available?
Yes. The drive is listed as Active Mature by Rockwell Automation, meaning it remains in production and fully supported. Availability varies by distributor; some channels show stock availability with short lead times . Note that newer PowerFlex 755T and 755TS models with TotalFORCE technology are also available for advanced applications requiring predictive maintenance and harmonic mitigation.
The Allen-Bradley 1794-OE4 is a 4-channel analog output module for the FLEX I/O system. It provides 4 single-ended, non-isolated outputs with software-selectable voltage (±10V, 0–10V) or current (0–20 mA, 4–20 mA) ranges, offering 12-bit plus sign resolution and 1.024 ms conversion rate for all channels.
