1. General information
The CSMIO-MPG module is used to provide the 6-axis CSMIO/IP series controllers with a manual pulse
generation (MPG) function. The CSMIO-MPG is a separate module designed to connect it to the
CSMIO/IP controller via the CAN bus.
By using the manual pulse generator, it is possible to manually control a maximum of 6 axes precisely
without using the MACH3 program.
Like the CSMIO/IP, the CSMIO-MPG requires 24VDC power. Digital inputs and outputs are optically
isolated and filtered. In the v2 version of the module also encoder inputs have an optical isolation.
The CSMIO-MPG is enclosed in a compact enclosure designed for DIN-rail mounting. This makes
mechanical and electronic installation in a control cabinet much simpler.
The manual pulse generation module is equipped with 3 digital inputs of multiplier selection (x1, x10,
x100), 6 digital inputs of controlled axis selection, 1 digital input for general purposes, 2 analog inputs,
2 digital outputs for general purposes and E-STOP circuit.
The manual handwheel encoder compatible with CSMIO-MPG module is available separately in CS-Lab
online store.

1.4 Changes regarding to previous version of CSMIO-MPG module
The main change regarding to the previous version is lack of configuration switches. The change is due
to implementation of optical isolation on inputs of a handwheel encoder. This way we get higher
resistance to interferences, especially when the handwheel we use has no differential outputs. In this
situation we need line polarization when we use handwheels without the differential outputs. On the
configuration jumpers there was also a switch responsible for CAN bus termination. Currently there is
a terminator included which should be plugged in if the module is the last device on the CAN bus. If we
have only CSMIO-MPG module connected to the CAN bus, then we plug in the terminator on right DB9
connector.
2. Safety
The CSMIO-MPG device is powered by 24VDC low voltage. I / O control lines are optically isolated, and
the PC connection is galvanically isolated. The device does not constitute a direct threat to the health
or life of the user.
When designing a complete control system, you should draw attention to all issues, so that the entire
system does not pose any hazard during use.
Pay special attention to the emergency stop circuit. The control system must be designed in such a
way that when you press the emergency stop mushroom, the controlled machine immediately stops
all axes. You should also consider the possible failure of any system components such as the main
controller, or axis drives.

3. Recommendations for mechanical installation
Here is an example - components arrangement in the control cabinet.
Caution is advised during the mechanical and electrical installation. Poorly tightened cables may cause
many problems; it’s also very difficult to find such a defect while launching/using the system.

The outputs have 50mA load. Do not
overload outputs. You should also pay
attention, if large inductances are
connected, you may need to use an
additional surge diode, preferably as
close
to the coil as possible.

5. CSMIO-MPG module configuration
CSMIO-MPG module version V2 does not require any configuration. However there are some
differences in connection way - it depends on whether handwheel encoder outputs are common or
differential. Both connection ways were shown in next chapter.
5.1 Termination of CAN bus and RS485
Some expansion modulef from CSMIO devices family have termination switch of CAN bus and RS485.
CSMIO-MPG v2 module does not have any configuration switches and due to that it is required to plug
in a special Terminator if CSMIO-MPG v2 is the only or last module in line.
For example:
1. CSMIO/IP-x CSMIO-IO CSMIO-ENC CSMIO-MPG (external terminator)
2. CSMIO/IP-x CSMIO-MPG (external terminator)
3. CSMIO/IP-x CSMIO-MPG CSMIO-IO (termination switched on in CSMIO-IO module)

7. Mach3 configuration
One of advantages of the CSMIO-MPG module is that you almost do not need to configure it.
•After CSMIO/IP-S controller connection you should turn
the power on and launch Mach3 program.
•In the “PlugIn Control” menu choose “CSMIO-IP-
P_plugin”
•In the diagnostic window go to the “Expansion
modules” tab.
If connections are correct, the CSMIO-MPG module should
appear on the list of modules detected by our controller.
Next – in the Mach3 program- turn on
the MPG function. To do this – click on
the “Config/Ports and Pins” and go to
the “Encoder/MPG’s” tab and select
MPG#1.
From now on the module is ready to
work.
7.1 Multiplier range selection.
The basic assumed distance unit is 1/10000 of a Mach3 unit, namely 1/1000mm (1um) or 1/10000
inch depending on used unit imperial or metric.
The CSMIO-MPG module has three inputs of
multiplier selection. It is possible to choose if
these inputs switch the resolution between:
•0.0001 / 0.001 / 0.01 of the unit
•0.001 / 0.01 / 0.1 of the unit
or
•0.01 / 0.1 / 1.0 of the unit
You can select it in the plugin’s configuration - “Config/Config Plugins” menu, click “CONFIG” area,
next to the CSMIO-IP-P-CS-Lab-s.c.” and go to "Other" tab. In the “MPG Resolutions” group select the
desired multipliers.
