The 22D-D1P4H204 PowerFlex 40P Adjustable Frequency AC Drive by Allen-Bradley is part of the PowerFlex 40P series, which is used for controlling 3-phase induction motors in closed applications with the need for speed control. The drive features removable MOV, an integral DC brake transistor, and a DIP switch with selectable Sink/Source controls, and it provides robust overload protections of 150% for 60 seconds and 200% for 3s. The drive has an output current rating of 1.4A with 0.4kW (0.5HP) output power at 380 to 480V AC operating voltage range, and it has input ratings of 1.4KVA and 1.8A at 342V AC to 528V AC input voltage. The 22D-D1P4H204 has a tolerance range of ±10% at 48 to 63Hz frequency, and its displacement power factor is 0.98 across the whole speed range. The drive provides BUS fault trips for both under voltage and over voltage, and it has 300% instantaneous current fault limit. The 22D-D1P4H204 has a removable Metal Oxide Varistor, which protects against ground fault trips and offers Class 10 Electronic Motor Overload protection by using the i2 t protection Algorithm.

The 22D-D1P4H204 utilizes the V/Hz and Sensorless Vector control for motor control, and it uses the Sinusoidal Pulse Width Modulated Signal. It has ±1% of the base speed regulation across an 80: 1-speed range, in an open-loop with slip compensation, and it has ±0.05% of the base speed regulation across a 20: 1-speed range using encoder device. The 22D-D1P4H204 has 7 (5 programmable, 2 dedicated) digital inputs, with 24V DC sink or source control, selectable via a DIP switch, and 2 isolated 0 to 10V DC and 4 to 20mA analog inputs, with 100kohm and 250ohm of input impedance, and an accuracy within 0.5% of the maximum output frequency. The 22D-D1P4H204 also has 1 programmable Form C relay output, with 1 non-isolated (voltage or current) analog output, and it has a dual-channel incremental encoder with 50%, +10% duty cycle. It has a human interface module, with a display fault reset button function, and it can be programmed using the integral RS-485 communication port, with the capability for PC programming. The 22D-D1P4H204 has a drive operating temperature of –10 to 50°C (14 to 122°F), with 5 to 95% non-condensing relative humidity range, and it is stored at –40 to 85°C (–40 to 185°F).
