3.2 Power Supply
3.2.14 Power supply circuitry (only MAC402)
The MAC402 supply is split into 2 individual circuits with no galvanic isolation in between
the circuits. The control circuitry requires a voltage (P+ and P- terminals) in the range
18 to 32VDC and the main power circuitry (M+ and M- terminals) must be supplied with
+8 to 48VDC nominal (max. 53VDC). Having 2 independent supply circuits offers the
feature that the supply voltage for the power circuitry (+8-48VDC) can be removed for
safety reasons, while the control circuitry can continue operating and thus keep the po
-
sition counter updated and keep other vital functions such as communication active.
The circuit above is shown with an emergency relay (box) which can be omitted if the
application does not require this safety feature. There are shown examples of Emergency
stop and relay in

The internal power dump is intended to cover 90% of all applications but if the error
message “overvoltage” is monitored, an external power dump unit must be connected
such as the JVL type PSU00-PD1. See also
