Product information

 AC30 Catalogue

The AC30 variable speed drive has been designed to provide users with exceptional levels of control, from simple open-loop pumps and fans through to closed-loop process line applications. Its flexible and highly modular construction enables a wide range of communications and I/O modules to be easily added as required. The AC30 has been designed with simplicity in mind, but this doesn't compromise its functionality. Integrated macros for a range of applications and PLC functionality enable more capable users to create sophisticated control that would previously have required a separate PLC. Designed for operation in environment class 3C3 and 3C4 for Hydrogen Sulphide (H2S) as standard (tested at 25 ppm for 1200 hours), temperatures up to 50 °C with optional integrated EMC filter to C2 1st environment and DC link choke to reduce line harmonics. AC30 also complies with RoHS substance restrictions in accordance with EC Directive 2011/65/EU

  • Ethernet TCP/IP as standard
  • I/O expansion options
  • Support for popular industrial fieldbuses
  • Chassis or through-panel mount as standard

 - Simplicity
  • Advanced control with Parker Drive Developer (PDD) software tool
  • Multi-language graphical keypad
  • Quick start wizards
  • Terminal covers removeable with drive in-situ

 - Reliability
  • Conformally coated for harsh environment protection as standard
  • Spring clamp control terminal connections
  • Isolated power stack cooling with removable fan

Designed to put you in control of your energy savings:
AC30 variable speed drives are supplied complete with a raft of features designed to simplify pump and fan control. In addition to quick setup, dedicated pump and fan macros, there are a number of other features dedicated to energy-saving pump and fan control such as :

• Automatic belt breakage detection : Interactive monitoring of the running conditions of a fan allows AC30 to detect a breakage in the drive belt between the fan and motor, stop the motor and indicate an alarm condition.

• Catching a spinning load - "fly-catching" : The fan control algorithms enable the AC30 to detect when a fan is free-wheeling and to regain control of it before running it at the commanded speed.

• 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.

• Intelligent Pump Profiles : Our advanced intelligent pump control algorithms monitor motor loads and provides users with a number of features designed specifically for pump control applications, such as :
  - Pump dry running protection
  - Flow detection (low and no-flow)
  - Blocked pump detection

• 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.
