Basic Functions Overview

The application software consists of a wide range of basic features which enables the drive to control any application using the iC2-Micro
drive.

Reference Handling

3.6.2.2
References from multiple sources, matching the needs to control the application, are freely definable.
Reference sources are:
Analog inputs
l
Digital inputs either as pulse input
l
Reference from a fieldbus
l
Internal settings
l
Local reference from control panel
l
Built-in potentiometer on control panel
l
Reference signals can be added generating the reference to the frequency converter. The final reference is scaled from -100% to 100%.
Two Setups
3.6.2.3
The frequency converter offers 2 setups. Each setup can be parameterized independently to match various application needs.
Switching between setups is possible during operation, allowing fast changeover.
Ramps
3.6.2.4
Linear, Sine ramp, Sine 2 ramps are supported in the frequency converter. The linear ramps provide a constant acceleration. The Sine
ramps provides a non-linear acceleration with soft transition at start and end of the acceleration process.
Quick Stop
3.6.2.5
In some situations, it may be required to stop the application in a quick way. For this purpose, the drive supports a specific deceleration
ramp time from the synchronous motor speed to 0 RPM.
Limit Rotation Direction
3.6.2.6
The rotational direction of the motor can be preset to run in 1 direction only (clockwise or counterclockwise), avoiding unintended
rotation direction.
3.6.2.7 Motor Phase Switch
If motor phase cables have been installed in an incorrect order during installation, the rotation direction can be changed. This eliminates
the need to change the order of motor phases.
3.6.2.8 Inching with Jogging Modes
The frequency converter has predefined speed settings for use during commissioning, maintenance, or service. The jogging-mode
operation is set at preset speed.
3.6.2.9 Frequency Bypass
Specific motor frequencies can be bypassed during operation. The feature helps to minimize and avoid mechanical resonance of the
machine, limiting vibration and noise of the system.
