AC20 IP20 37kW/75A 400V Size 6 AC drive C3 filter

The advanced compact AC20 drive is a highly functional yet economical solution for general motor control applications in the range of 2 hp to 250 hp (1.5 kW to 180 kW). The AC20 offers speed or torque control without open loop for AC induction or PMAC motors, and with the optional encoder feedback board fitted, with closed vector control of AC induction motors.
The AC20 is packed with features normally associated only with system drivers, including two IO/feedback expansion card slots, Safe Torque Off and a built-in Ethernet port that supports most industrial Ethernet protocols, including ProfiNet and Ethernet IP as standard. Additional user-installable communication cards are also available.

Software features:
- Profinet IO and Ethernet IP protocols as standard, via the built-in Ethernet port.
- Winding machine function block: Diameter calculation, inertia compensation, torque calculation and taper are combined to create speed and torque control winding functions.
• Fånga en snurrande last – ”flugfånga”: Fläktstyrningsalgoritmerna gör det möjligt för AC20 att upptäcka när en fläkt roterar fritt och återfå kontrollen över den innan den körs med den inställda hastigheten.
- PID control: Multiple PID control loops can be programmed to monitor process variables and adjust the motor speed accordingly to achieve the desired variable setpoint.
- Essential services (fire mode): If the fire mode is selected via digital input, the inverter runs continuously at the maximum programmed speed and ignores all other control signals and alarm conditions.
- Energy optimisation: Under constant speed conditions, the motor's power waveforms are optimised by the drive to reduce the motor's energy consumption without compromising performance.
- Skip frequencies: Up to four speed and frequency bands can be programmed to avoid resonance points on the load, reducing vibration, wear and noise.
- Programmable multi-stage speed control: 8 cyclical stages can be programmed with different travelling speeds and times.
- Process timers: Multiple operating hours can be programmed to generate alerts that coincide with process maintenance intervals.
- 70 software function blocks that can be interconnected with up to 200 links provide a powerful application platform.

Parker Drive DSELite software:

Parker's Drive System Explorer (DSE) Lite drive configuration software is an easy-to-use drive configuration software package designed to make programming your application as simple as possible without compromising functionality.
DSE Lite är baserad kring en enkel blockprogrammering och ett intuitivt användargränssnitt som stöder användardefinierade konfigurationer och erbjuder realtidsövervakning och diagram. DSE Lite låter användaren skapa, parametrisera och konfigurera användardefinierade applikationer samt parametrisera och ansluta fasta motorstyrningsblock med upp till 200 ”länkar”.
Thanks to the online help and pre-configured macro templates, users can achieve optimal drive system configuration without having to navigate through complicated parameter menus.

Enhanced features of the AC20 include:

- High-speed connection via Ethernet
- Network scanning function
- Identification of driving networks
- Installs firmware via Ethernet
- Save a project to the built-in flash memory
- Compatibility with AC30 series oscilloscope software.
