The operation of the ARS 2100 SE series servo drives requires a 24V voltage supply source for the
electronics supply, which is connected to the terminals +24V and GND24V.
The connection to the supply for the power output stage is either made to terminals L and N for AC
supply or to ZK+ and ZK- for DC supply.
The motor is connected to terminals U, V and W. The motor temperature switch (PTC or normally
closed contact) is connected to terminals MT+ and MT–, if it is lead into one cable together with the
motor phases. If an analogue temperature sensor is used in the motor (for example KTY81), the
connection is realized via the encoder cable to [X2A] or [X2B].
The connection of the shaft encoder via the D-Sub connector to [X2A] / [X2B] is roughly shown in
Figure 12.
The servo drive must be connected to ground with its PE connection.
The servo drive must be completely wired first. Only then the operating voltages for the DC bus and
the electronics may be switched on.
Caution!
In the following cases the servo drive will be damaged:
in the case of inversed wiring of the operating voltage connections,
excessive operating voltage or
in the case of confusing the connections for operating voltage and motor!
Caution! Dangerous voltages.
The signals for the temperature sensor "MT-" (PIN 4) and "MT+" (PIN 5) at the motor
connector [X6] are not connected to Protective Extra Low Voltage (PELV).
These connections are designed for temperature sensors that are not safely separated.
The safe separation from Protective Extra Low Voltage (PELV) is performed within the
ARS 2000 SE.
