The DELTA VFD022E21A operates within a rated voltage range of 200-240V for 3-phase inputs at 50/60Hz. It features a frequency output range of 0.1-599Hz with 0.01Hz resolution. The inverter supports a voltage tolerance of ±10% (180-264V) and frequency tolerance of ±5% (47-63Hz). It includes auto-torque compensation for starting torque up to 150% at 3.0Hz and DC braking with adjustable start and stop times (0-60 seconds). The product is rated for ambient temperatures from -10°C to +50°C, with a non-condensing design that prevents freezing.
The VFD022E21A offers multi-step selection (0-15), jog control, and accel/decel inhibit functions for precise motor control. It supports two external acceleration/deceleration switches and includes counter functionality. The inverter also provides base block inputs (NC/NO) and auxiliary motor control options, allowing flexible integration with external systems. The product supports sink/source (NPN/PNP) signal selection and ACI/AVI/AUI configurations for enhanced control versatility.
With a starting torque capability of 150% at 3.0Hz, the VFD022E21A ensures strong initial acceleration for heavy loads. Its skip frequency feature allows three adjustable zones for smooth speed transitions, reducing mechanical stress during operation. The DC braking system provides rapid deceleration with adjustable start and stop times (0-60 seconds), making it suitable for applications requiring precise speed control and minimal vibration.
The DELTAVFD022E21A is an industrial Servo Motor. Selection should be based on the documented characteristics and the requirements of the intended application.
