Power Supply Requirement
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 85VDC, for UL from 30
to 85 VDC.
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 specially designed power supplies can be used.
Recommended Power supplies:

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. 200mA (no load on the outputs)
typ. 1.1A (all 10 outputs “on” with 100mA load and /Brake with no load)
max. 2.1A (all 10 outputs “on” with 100mA load and /Brake with 1A load)
Regeneration of Power / Regeneration Resistor
There are two possibilities to deal with power regeneration:
Option A: Connect an additional capacitor to the motor power supply. It is recommended to use a
capacitor >= 10’000 F (install capacitor close to the power supply!)
Option B: Install a Regeneration Resistor to X1 (RR+ and RR-). The threshold value of the
voltage depends on the used motor voltage power supply. The max. threshold value
must not exceed 88 VDC.
For UL applications, use option A.
