JetMove 108 7.1 Demands on the Power Supply Unit for Motor Operating Voltage
Jetter AG 45
If the solution just mentioned cannot be put into practice (in case of power supplies
that cannot be interrupted, or if batteries/accus are used), connect an external
capacitor of at least 470 µF / 100 V between circuit breaker and servo amplifier, in
order to limit the slew rate of the motor supply voltage.

Recommended wiring of the voltage Vmot
Always make sure there is an external circuit breaker to switch off the
power supply. Always switch off the power supply before installing the
motion system.
Always limit the inrush current of the motion system. Otherwise the
motion system can be destroyed.
Always use short wires of a large cross-section to connect the voltage
supply and the JetMove 108. If the lines are to be longer than 2 meters,
use twisted wires for the supply and earthing return line. If wires of
more than 20 meters are to be used, apply a capacitor of at least 1,000
µF (set for the maximum possible voltage) close to the X1 terminal.
If the same power supply is used for multiple motion systems, apply a
star-connection the electrical center of which consists of the supply
outputs. Connect each motion system to the general motor voltage
supply using different wires for either positive or feedback phases.
Connect the grounding wire / the shielding of the JetMove 108 with a
fixed earthing position. The JetMove 108 generates electro-magnetic
disturbances if its enclosure has not been earthed.
Apply a short connection of a large cross-section between the PE of the
servo amplifier and the connection to ground. Whenever this is
possible, mount the JetMove 108 on a metallized and earthed surface.
