Chapter 3: Getting Started with
Sensors and Motion Control Setup
3.1 Introduction
Tuning a SimplIQ drive to a motor is an ordered, step-by-step process. In this
"Getting Started" chapter, we go through the setup process step by step.
Note that this chapter does not contain all the detailed information for all product
types and cannot take into account every possible aspect of the drive setup.
3.1.1 Tune the Drive to the Motor
All motor and application types:
Set the switch functions for limits; enable functions, brakes, etc. This will create
the initial conditions for the motor to work.
Set the application limits for current, speed, and position. This will prevent
system constraints being violated later on.
Defining the sensors.
Selecting the motor type (DC, Stepper, Brushless).
Tuning the current controller.
Brushless motors only:
Commutation tuning (finding how to power the stator so that the motor will
develop maximum torque in the desired direction).
3.1.2 Tune the Motion Controller
For open loop stepping applications, you only need to set few parameters.
If you have a motion sensor, you may want the following:
Tune speed and position controls.
Set corrections for motor cogging and define the speed-dependent corrections
to the current loop.
3.1.3 Database Maintenance
All the steps until now have manipulated variables in the drive's database. The
last step is to check database validity, and to save the outcome in a permanent
(flash) memory.
3.2 Abort and Enable Switches
First, set the enabling switches.
The drive has several digital inputs (depending on the drive type). There are
several automatic functions that may be assigned to drive digital inputs.
It is important that at this stage you define which switches are used to abort or to
stop motion, as well as limit switches when applicable.
