CHAPTER 2 APPLICATION PACKAGE MOTION
The application package MOTION contains the operation modes:
•
stepper motor operation
•
electronic gearing
•
point-to-point positioning
These operation modes have an integrated position controller with a scanning period of
250 µs. This has the following advantages compared with an external position controller:
•
no need for encoder analysis in the control system
•
reduced amount of cabling required
•
minimum down times in the position control circuit resulting in a high quality of
control
The application package MOTION can only be operated with the operating software
DRIVEMANAGER (see chapter 4).

In the operation mode stepper motor operation the MC7000 can be directly driven by a
stepper motor control system and has the following properties:

•
angle precision to below 0.1°
•
reference run with zero-point correction
•
limit-switch analysis
•
12 digital inputs, 1 hardware-release, 6 digital outputs, 1 relay output
