The motor is connected to terminals U, V, W. The motor temperature switch (PTC or normally closed
contact) is connected to terminals MT+ and MT-, if the switch is integrated in one cable together with
the motor phases. If an analogue temperature sensor (for example KTY81) is used in the motor, it is
connected to [X2A] or [X2B] through the encoder cable.
The connection of the rotary encoder to [X2A] / [X2B] via the D-Sub connector is roughly shown in
Figure 25
.
The ARS 2300 servo drive must be connected to ground with its PE connector.
The ARS 2300 servo drive must be completely wired before the operating voltages for the DC bus and
the electronic system can be switched on. In the case of inverted wiring of the operating voltage
connections, an excessive operating voltage or a mix-up of operating voltage and motor connections,
the ARS 2300 servo drive will be damaged.
8.2 ARS 2300 complete system
The complete ARS 2300 servo drive system is shown in
Figure 27
. The following components are
required for using the servo drive:
 Mains main switch
 Fault-current circuit breaker, type B (RCD), AC/DC sensitive 300mA (if required by an application)
 Automatic circuit breaker
 ARS 2300 servo drive

Motor with motor cable
 Mains cable
A PC with a serial connecting cable is required for parameterization.
Install a three-phase automatic circuit breaker into the mains supply line:
 For the servo drives type ARS 2320, ARS 2320W: 32 A, slow-to-blow type (B32)

For the servo drives ARS 2340, ARS 2360W: 50 A, slow-to-blow type (B50)
