Capacitor: the capacitor, filters the voltage from
single phase bridge and recoveries the energy from the motor
during the deceleration phase.Capacitorʼs value,can be
obtained with following formula:
where:
V2 = Capacitor voltage between positive and negative at no
load speed.

Ground cable connections
AXOR advises to connect on an only one isolated bar.
The interconnection screw marked with symbol.
With only one wire we connect the isolated bar at the ground of the
electric box. From which it will start the ground connection to electrical
power net.
Donʼt make any bridge between the ground of the amplifiers, for
avoid closed loop ground interferences.
NOTE
ATTENTION!!!
For racks double ground connection is required both pin 13 and
ground screw “chassis ground” must be ground connected.

application)
N.B.
If during the deceleration phase green ok led switch-
off,voltage between positive and negative is excessive;
therefore we must increase the capacitor(parallel) or use
the regenerative modules.This modules are reccomended
specially with MS 140 and MS 200.

This resistance ,discharge the capacitor also when amplifier
is disconnected after power supply switch off.
The value can be calculated with the followig formula :
