3.4 Power supply
The power for the positioning system with the CMAX is
supplied via the following connections on the CPX terminal
(interlinking blocks with voltage input):
Interlinking block
CPX−EV−S... or
CPX−M−EV−S... (U
EL/SEN
)
The following is supplied with power via the operating
voltage supply for the electronics/sensors (U
EL/SEN
) of the
CPX terminal:
Ĉ Internal electronics of the CMAX
Ĉ Internal electronics of the VPWP
Ĉ Connected sensor interface (optional)
Ĉ Connected position measuring system.

)
Power is supplied to the following via the valve load supply
(U
VAL
) of the CPX terminal:
Ĉ 24 V load supply of the VPWP
Ĉ Brake output (digital output) of the VPWP.
Note
Operative malfunctions due to power supply outside the
tolerance.
The module with the lowest tolerance always determines
the permissible voltage tolerances.
· If the CMAX is used, special tolerances according to
Tab. 3/9 must be observed for the valve load supply
(U
VAL
) of the CMAX.
