3.2.28 Power supply circuitry (only MAC1500, MAC3000 & MAC4500)
The MAC1500, MAC3000 and MAC4500 supply is split into 2 individual circuits with full
galvanic isolation between the circuits. The control circuitry requires a voltage in the
range 18 to 32VDC and the power circuity must be supplied with 3phase 400 to
480VAC. Having 2 independent supply circuits offers the feature that the supply voltage
for the power circuitry (400-480VAC) can be removed for safety reasons, while the con-
trol circuitry can continue operating and thus keep the position counter updated and
keep other vital functions such as communication active.
P+/- must be per-
manently connected
if control circuitry
must be keept active
while main power is
disconnected.

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 resistor must be connect-
ed between the terminals PD and BO.
