FIGURE 1-4:
Note that the incoming digital 0V from the control card is grounded internally within the
power module (as shown in the Figure 1-4) to ensure user safety. When a PC or any
other device is connected to the control card there is therefore the possibility of a
"ground loop" occurring. If this is suspected, the user should first try to eliminate the
stray magnetic field causing the problem by relocating the offending transformer or by
using shielding. If this is not possible, then the equipment connected to the control
card should be isolated from the digital 0V.
Position and speed feedback transducers are connected to the control board directly
and not via the power module. No electrical isolation is provided on the control board
for these signals and so the transducers must be isolated.
Consult the dsPICDEM™ MC1 Motor Control Development Board (DS70098)
documentation for details of signal interfacing and how to connect in-circuit emulators
and debugging equipment.
