Power Supply Requirements
12.1
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 72 VDC.
The possible range is from 24 to 85 VDC.
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 chapter 15 Ordering Information) .
12.2
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 to be provided from the supply:
• min. 0.5 A (no load on the outputs)
• typ. 0.7 A (all 2 outputs “on” with 100 mA load and brake with no load)
• max. 2.0 A (all 2 outputs “on” with 500 mA peak load and brake with 500 mA peak load)
Do not connect the safety relays to the 24 VDC Signal Supply!
Use a separate power supply for the safety circuit
The 24 VDC supply for the control circuit must be protected with an
external fuse (3 A slow blow)

Regeneration
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!).
