Motion Application Overview
2.1
The Motion application enables position control with all motor control principles and motor types supported by iC7-Automation.
The following main functions are included in the Motion application:
Basic functions
l
Speed control
l
Torque control
l
Position control for both linear and rotary systems, including scaling of position unit and limit handling.
l
Positioning mode with relative, absolute, and touch probe positioning.
l
Gear mode for the synchronizing of 2 or more shafts.
l
Homing for defining the machine zero point.
l
Superimposed movement: Positioning on top of any underlying movement.
l
Touch probe handling including measurement of distance between sensors.
l
Basic Functions
2.2
I/O Control and Readouts
2.2.1
Depending on the hardware configuration of the drive, digital and analog inputs as well as digital, analog, and relay outputs are
available. The I/Os can be configured and used to control the application from the drive.
If functional extension options are installed in the drive, the relevant parameters and I/O selections are automatically visible in the
parameter structure.
Reference Handling
2.2.2
References from multiple sources can be defined, depending on the needs of the application.
Reference sources are:
Analog inputs
l
Digital inputs either as pulse input or digital potentiometer
l
Reference from a fieldbus
l
Up to 8 preset references (selectable by parameter, fieldbus, or digital inputs)
l
Local reference from control panel
l
Reference signals can be added, subtracted, and multiplied, generating the reference to the drive. The final reference is scaled from
-100% to 100%.
Ramps
2.2.3
Linear and S-ramps are supported. Linear ramps provide a constant acceleration and deceleration. S-ramps provide a non-linear
acceleration and deceleration, with a soft transition at the start and end of the acceleration and deceleration process.
Quick Stop
2.2.4
In some situations, it may be required to stop the application quickly. For this purpose, the drive supports a specific deceleration ramp
time from the synchronous motor speed to 0 RPM.
Limit Rotation Direction
2.2.5
The motor can be preset to run in one rotational direction only (positive or negative), avoiding unintended rotation direction.
