5.3 Expansion module MAC00-B41
5.3.13 Example - how to use gearmode with MAC00-B41.
The MAC00-B41 module offers a number of I/O possibilities that makes it very conven-
ient to use in Electronic gear applications.
An external encoder with various output configurations can easily be connected to one
of the multifunction I/O channels and also signals like Enable/disable motor can be estab-
lished using one of I/O terminals (I/O1 to I/O6).
The following pages describe in detail followings how to get the wiring sorted and also
how to setup the motor in general.
The example will cover:
- Hardware: Connecting the encoder to the MAC00-B41
- Setting up relevant parameters for using gear mode
- Optionally setting up input 1 for enabling/disabling motor operation (enable input)
- Optionally setting up input 2 as a "coupling" input for enabling the motor to follow
the encoder or staying stationary at 0 RPM (keeping the position).
Step 1
Start by connecting the encoder to the multifunction IO channel 1 according to the illus-
tration below.
This example is showing an encoder equipped with a 24V PNP (source) output.
A serial resistor must be inserted since the IO channels at the MAC00-B41 is made for
handling RS422 levels which means that no more than 5V must be applied. Higher levels
will be destructive!
Remember to set the internal dip switch correctly in order to setup the module to handle
a signal source with a PNP output.

Important ! :
If possible avoid connecting the terminals to the cable since internal capacitances in the cable can interfere
