Main Features and Advantages
The 22B-D4P0N104 stands apart in the compact VFD market through its fusion of sensorless vector control and user-centric design. The drive’s Autotune feature allows the 22B-D4P0N104 to adapt to individual motor characteristics, delivering exceptional speed regulation and very high torque levels across the entire speed range. With linear acceleration, excellent current regulation, and best-in-class digital input response time, the drive accelerates into at least 150% load, making it ideally suited for demanding applications where traditional V/Hz drives fall short.
Compact yet powerful:
The 22B-D4P0N104 packs an impressive array of capabilities into its Frame B enclosure. Despite measuring only 180 × 100 × 136 mm, the drive incorporates an integrated brake IGBT (supporting external braking resistors), six configurable digital inputs, two analog inputs, one bipolar analog input, one relay output, and one analog output. This rich I/O structure eliminates the need for external expansion modules in most small-machine applications, reducing both panel space and total project cost.
Integrated intelligence:
Beyond standard motor control, the 22B-D4P0N104 embeds Timer, Counter, Basic Logic, and StepLogic functions that can substantially reduce hardware design costs and simplify control schemes. The built-in PID controller transforms the drive into a standalone process controller capable of automatically regulating motor speed for flow, pressure, or temperature loops. The StepLogic feature enables logic-based step sequencing with preset speed settings, where each step can be programmed for specific speed, direction, and acceleration/deceleration profiles—functionality typically reserved for higher-tier drives.
Robust protection and reliability:
The provides 150% overload capacity for 60 seconds and 200% for 3 seconds, ensuring robust protection against transient load spikes. A relay precharge circuit limits inrush current, while a removable MOV-to-ground provides trouble-free operation on ungrounded distribution systems. Adjustable PWM frequency up to 16 kHz delivers quiet motor operation and minimizes acoustic noise in occupied environments. DIP switch-selectable 24V DC sink or source control offers maximum flexibility for control wiring.
