Parker Variable Speed Drive, 2.2 kW, 1 Phase, 220 → 240 V ac, 10 A, AC20 Series

The Parker AC20 advanced compact drive is a highly featured yet economical solution to general purpose motor control applications in the range of 1.5kW to 180kW. The AC20 provides open loop speed or torque control for AC induction or PMAC motors, and with optional encoder feedback card fitted, closed loop vector control of AC induction motors. The AC20 is packed with features normally only associated with system drives, including two IO/feedback expansion option slots, Safe Torque Off and an onboard Ethernet port that supports major industrial Ethernet protocols including ProfiNet and Ethernet IP as standard. Further user installable communications option cards are also available. The AC20 general purpose drive provides advanced Ethernet connectivity and Safe Torque Off for open or closed loop AC induction and PM motor control in applications up to 180kW.

Compatibility with the AC30 Series Oscilloscope software
3 Analogue outputs, 2 analogue inputs, 8 digital inputs, 2 digital outputs + 1 Relay output
Earth Leakage Current: >10 mA (all models)
Product Enclosure Rating: IP20 (Europe)
Maximum Switching Frequency: 10 kHz
Output Frequency: 0 to 590 Hz
Operating Humidity: Maximum 85 % relative humidity at 40 °C non-condensing

PID Control: Multiple PID control loops can be programmed to monitor process variables and adjust the speed of the motor accordingly to achieve the required variable setpoint
Essential services (Fire mode): Selected via digital input, Fire mode will cause the drive to run continuously at the maximum programmed speed ignoring all other control signals and alarm conditions
Energy Optimisation: Under constant speed conditions, the motor power waveforms from the drive are optimised to reduce motor energy consumption without compromising performance
Skip Frequencies: Up to 4 speed and frequency bands can be programmed, to enable resonant points on the load to be avoided, reducing vibration, wear and noise
Programmable multi-stage speed control: 8 cyclable stages can be programmed with different running speeds and times

Profinet IO and Ethernet IP protocols as standard, though the built-in Ethernet port
Catching a spinning load - "fly-catching": The fan control algorithms enable the AC20 to detect when a fan is free-wheeling and to regain control of it before running it at the commanded speed
