AC30 is supplied complete with many 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 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 provide 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 Optimization

Under constant speed conditions, the motor power waveforms from the drive are optimized to reduce motor energy consumption without compromising performance.

Skip Frequencies

Up to 4 speed and frequency bands can be programmed in the AC30, to enable resonant points on the fan to be avoided, reducing vibration, wear and noise.

Timed Run Function

10 daily start/stop events can be programmed with different running speeds across a 7 day period. This function requires the optional Real-Time Clock (RTC) module and is ideally suited to applications where regular operating patterns or periods of activity need to be accommodated such as in a production environment.

Process Timers

Multiple hours-run timers can be programmed to generate text alerts on the drive keypad to coincide with process maintenance intervals.
