Power supply circuitry (only MAC400)
The MAC400 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 30VDC and the
power circuity must be supplied with 90 to 240VAC. Having 2 independent supply cir-
cuits offers the feature that the supply voltage for the power circuitry (90-240VAC) can
be removed for safety reasons, while the control circuitry can continue operating and
thus keep the position counter updated and keep other vital functions such as communi-
cation 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 section 5.6.2
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
.
