Operating Manual dryve D1, ST-, DC-, EC/BLDC-Motor Control System - V2.4
NOTE
Follow the instructions regarding PELV circuits (p.20) and use suitable components for earthing.
NOTE
The logic voltage does not supply the motor windings. If the logic voltage supply collapses, the motor will stop in an
uncontrolled manner or might even accelerate if build in in vertical or rotating applications.
4.2.1 Power supply selection
For the correct dimensioning of the power supplies to be used, various aspects must be considered
1.
Number of used motor controller per power supply
2.
Maximal current draw of each motor (consider the set Boost)
3.
Maximal current draw of used peripheral devices (e.g. sensors and other devices)
4.
Maximal current draw of the Logic
The current draw must be added voltage wise. This sum defines the minimal current supply capacity of the power supply.
NOTE
If different power supplies are used for the load and logic voltage, the grounds of both power supplies must be connected to
create a common potential.
CAUTION !
The connection terminals are designed for single wires.
A firm connection cannot be guaranteed due to improper multiple occupancy. There is a risk that wires may slip out of the
terminals and cause short circuits.
If several signals/wires have to be connected to one terminal, they must be brought together via an external terminal and
connected from there with a single wire.
