) Communication RS-485 multidrop serial link integrated in the starter, for Modbus Systems, with RJ45 connector Transmission speed: 4800, 9600 or 19200 bps Maximum number of ATS48 soft starters connected: 18 Other uses: v Connection to a remote keypad display v Connection to a PC v Connection to other buses and networks via communication options Protection Thermal Built-in, starter and motor (calculated and/or thermal protection with PTC probes) Line Protection Phase failure protection, indicated by output relay Current settings The nominal motor current, In, can be adjusted from 0.4 to 1.3 times the starter nominal current. Adjustment of the maximum starting current from 1.5 to 7 times the motor In, limited to 5 times the starter nominal current. Starting mode By torque control with starter current limited to 5 In maximum. Factory setting: 4 In for standard operation on 15 s torque ramp Stopping mode Freewheel stop Freewheel stop (factory setting) Controlled stop on torque ramp Programmable between 0.5 and 60 s (for pump applications) Braked stop Controlled dynamically by the flux

Note: Power factor correction capacitors can only be used upstream of the ATS48 soft start and only powered up at the end of starting. The soft starter must be grounded to meet regulations concerning leakage currents ( d 30 mA). If the installation involves several soft starts on the same supply line, each soft starter must be grounded separately.
