FUNCTIONS OF THE VACON®AC DRIVE
•You can select one of the preset applications for your process: Standard, Local/Remote,
Multi-step speed, PID control, Multi-purpose or Motor potentiometer. The drive
automatically makes some of the necessary settings, which makes the commissioning
easy.
•Wizards for the first startup and the Fire mode.
•Wizards for each application: Standard, Local/Remote, Multi-step speed, PID control,
Multi-purpose or Motor potentiometer.
•The FUNCT button for an easy change between the local and the remote control place.
The remote control place can be I/O or fieldbus. You can make a selection of the remote
control place with a parameter.
•8 preset frequencies.
•Motor pontentiometer functions.
•A joystick control.
•A jogging function.
•2 programmable ramp times, 2 supervisions and 3 ranges of prohibited frequencies.
•A forced stop.
•A control page to operate and monitor of the most important values quickly.
•A fieldbus data mapping.
•An automatic reset.
•Different pre-heat modes to prevent condensation problems.
•A maximum output frequency of 320 Hz.
•A Real time clock and timer functions (an optional battery is necessary). It is possible to
program 3 time channels to get different functions on the drive.
•An external PID controller is available. You can 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. You can make the selection with a digital input.
•A function for PID setpoint boost.
•A feedforward function to make the response to the process changes better.
•A process value supervision.
•A Multi-pump control.
•A maintenance counter.
•Pump control functions: priming pump control, jockey pump control, pump impeller
auto-cleaning, pump input pressure supervision and frost protection function.
