11 Power Supply Requirements
Motor Power Supply
The calculation of the needed power for the Motor supply is depending on
the application and the used motor. The nominal supply voltage is 72VDC.
The possible range is from 24 to 85VDC.
ATTENTION:
The motor supply can rise up to 95 VDC when braking.
This means that everything connected to that power supply needs a
voltage rating of 100 VDC. (Additional capacitors, etc...). Due to high
braking voltage and sudden load variations of linear motor
applications,
only compatible power supplies can be used (see Ordering
Information on page 20).
Signal Power Supply
The logic supply needs a regulated power supply of a nominal voltage of 24 VDC.
The voltage must be between 22 and 26 VDC.
Current consumption:
min. 0.5A
(no load on the outputs)
typ. 0.7A
(all 2 outputs “on” with 100mA load and /Break with no load)
max. 1.61A (all 2 outputs “on” with 370mA peak load and /Break with
370mA peak load)
Do not connect the safety relays to the 24VDC Signal Supply!
Use a separate power supply for the safety circuit!
12 Regeneration of Power
If the power supply rises too high when breaking, connect an additional capacitor to
the motor power supply. It is recommended to use a capacitor >= 10’000 μF
(install capacitor close to the drive supply!)
