VACON® 100 FLOW
Application Guide

1.5 Functions of the AC Drive

• Easy setup functions
- Applications with preset parameters and I/O configuration for your process: Standard, HVAC, PID control, Multi-pump
- Start-up wizards for fast and easy parameterization
• Navigation functions
- The [FUNCT] button for an easy change between the local and the remote control place (I/O or fieldbus)
- A control page to operate and monitor of the most important values quickly
• Advanced monitoring functions
- Multimonitor
- Trend curve
• Fieldbus and I/O control
• Motor control
- Open loop control with frequency reference
- Support for induction, permanent magnet, and synchronous reluctance motors
- Identification run for setup of motor parameters
- Flux and DC brake
• Start and stop logic configuration
• Reference selection and handling
- 8 preset frequencies
- Motor potentiometer functions

• PID control
- An external PID controller is available. Use it, for example, to control a valve with the I/O of the AC drive.
- A sleep mode function that automatically enables and disables the operation of the drive to save energy
- A 2-zone PID controller with 2 different feedback signals: minimum and maximum control
- 2 setpoint sources for the PID control. Selection to be made with a digital input.
- A function for PID setpoint boost
- A feedforward function to make the response to the process changes better
• Pump control
- A multi-pump control for the single drive and multidrive systems
- The multimaster and multifollower modes in the multidrive system
- A multi-pump system that uses a real time clock to autochange the pumps
- Priming pump control, jockey pump control, pump impeller auto-cleaning, pump input pressure supervision, and frost pro-
tection function
• Mechanical brake control
• Timer functions and a real-time clock and (an optional battery is necessary)
• Fire mode
• Diagnostic and maintenance functions
- Variety of configurable protection functions including user-defined faults
- Supervision functions for frequency and motor variables and analog inputs
- Motor overload protections
