3.0 BOARD DESCRIPTION

4.0 POWER TERMINALS AND CONFIGURATION JUMPERS

Before connecting the power supplies, follow steps below.

4.1 Power terminals and configuration Jumpers for inputs

These opto-isolated inputs require an external 5VDC to be powered. It is recommended
when isolation between PC and power of inputs is required (set jumpers in REQUIRED
position). Be sure that the GND terminals are common to the GND inputs power.

___________________________________________________________________________

User’s Manual Page 3

C32 (Rev. 5) User Manual

If isolation is not required, don't connect any external power supply to these terminals
and set jumpers in "NOT REQUIRED" position.

4.2 Power terminals and Jumper for Driver monitor circuit

Connects an external (5V) power supply, when using drivers with error or alarm signal
common to its power GND. In this case, set jumper in “REQ” position.

In other cases don't connect any power supply to those terminals and set jumpers in
“NOT REQ” position.

4.3 Controller selection jumpers (IEEE1284/SS)

If using a normal LPT port as control interface, set jumper in “compatible” position.

___________________________________________________________________________

User’s Manual Page 4

C32 (Rev. 5) User Manual

By other hand, if using a SS or an ESS as controller, set jumper in “Not compatible”

position

4.4 Driver Fault Jumpers

Some C34 boards have a special circuit that allows to the C32 detecting when the C34
has been disconnected.
To enable this detection function is required set jumper of the axes to be used in 1-2
position. If the C34 does not include this disconnection detection circuit or this function
is not going to be used, set all jumpers in 2-3 position (see the respective C34 User
manual).
If this function is enabled and any C34 is disconnected, the C32 will go to standby mode
and a driver error will be shown.

5.0 CONFIGURATION DIPSWITCH

DIPSWITCH allows activating or deactivating the SCHP detection function, and
selecting the driver to use and delays an enable signal for external devices.

5.1 Position 1

The enable output (Pin 17-Port 2) will be activated when the driver enable process
starts. A delay in the signal activation time could be added by selecting the OFF position
in the DIPSWITCH.

The table below shows the delay time for each supported driver.

SWITCH 1 OFF: Delayed enable output (Pin 17-Port 2).
SWITCH 1 ON: Non Delayed enable output (Pin 17-Port 2).

5.2 Position 2

Safety Charge Pump “SCHP”. (Pin 17 “Port 2”)

This board takes advantage of Mach ability to send a specific frequency through one of
the pins of the parallel port when the program is in control of the system.

Selecting the SCHP operation mode
