Power Supply Requirement
Power Supply motor
The calculation of the needed power for the motor supply depends on the application and the used
motor. The nominal supply voltage is 72 VDC. The possible range is from 24…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.
(Power supply itself, additional capacitors, etc…)
For the same reason, the 24VDC supply for the signal, shall not be connected
together with the motor supply. If the motor is supplied with 24 VDC, this must be an
additional, independent power supply.

Power Supply signal
The logic supply needs a regulated power supply of a nominal voltage of 24 VDC. The voltage must
be between 22 and 48DC.
Power consumption:
10W
Regeneration of Power / Regeneration Resistor
There are two possibilities handle power regeneration:
Option A:
Connect an additional capacitor to the motor power supply. It is recommended to use
a capacitor >= 10’000
μ
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.
