Power consumption calculation example
The power supply module (MSE 1201, MSE 1202) provides the electrical power for
further modules and encoders. If the power provided does not suffice to operate the
desired system configuration, a further power supply module must be used.
The power consumption is specified for each module (see table). The power
consumption of the connected HEIDENHAIN encoders can be calculated from the
catalog data (supply voltage x current consumption). For all other consumers (e.g..
inductive and analog sensors), the connected load must be known. The sum power of
all consumers must not exceed the rated power of the power supply module(s).
The following example illustrates this calculation.
Components to be supplied
Encoders: 8 x ACANTO AT 1217, 12 x SPECTO ST 1288, 2 x LS 388 C,
2 x temperature sensors 20 V/100 mA
Modules: 1 x MSE 1114 basic module, 1 x MSE 1314 axis module,
2 x MSE 1388 axis modules, 1 x MSE 1501 compressed-air
module,
1 MSE 1332 analog module
