3.2
Power supply
3.2.1
Three-phase AC power supply
The ARS 2300 servo drive fulfils the following requirements:
Nominal frequency range 50-60Hz
±
10%
Electrical impulse load capacity for possible combination of several servo drives. The servo drive
ARS 2300 allows dynamic conversion in both directions between motor and generator operation
without dead times
No parameterisation by user necessary
3.2.1.1 Behaviour during switch-on, behaviour during normal operation and control
characteristics
As soon as the servo drive ARS 2300 is supplied with the input voltage, the DC bus is
charged(< 1 s) using the brake resistor as a precharging resistor, the DC bus relay deactivated.
After precharging of the DC bus the relay is energized and the DC bus is coupled hard to the
mains power without the precharging resistor.
3.2.2
DC bus coupling, DC supply
3.2.2.1 DC bus coupling
It is possible to couple multiple ARS 2300 servo drives when they have the same DC bus voltage.
3.2.2.2 DC-supply:
The direct DC supply is supported for a supply with voltages
≥
60 VDC by the DC-bus connection
instead of the connection to the mains
The digital motor temperature measurement system requires a DC bus voltage of
230 VDC minimum. Below this voltage, the system will always identify the digital motor
temperature sensor as open. In this case you must either use the analogue temperature
sensing (if the temperature sensor is safely separated, see
chapter 8.6.11
) or disable the
temperature sensing at all.
3.2.3
Mains fuse
Install a three-phase automatic circuit breaker into the mains supply line:
For servo drive type ARS 2320, ARS 2320W: 32 A, slow-blow type (B32)
For servo drive type ARS 2340, ARS 2360W: 50 A, slow-blow type (B50)
