16 Set-up | Application manual: Waste water pump | 1SFC132104M0201 4.4 Recommended change of parameter values This chapter describes the recommended parameter values. For more information about the parameters for the PSTX softstarter see: 1SFC132081M0201 - Softstarters Type PSTX30...PSTX370, Installation and Commissioning Manual. 4.4.1 05 Slow speed (pump cleaning reverse) Menu u Parameters u Complete list u 05 Slow speed See Figure 15 for navigation. These are the recommended settings for Slow speed: 1. Set the parameter 05.03 Slow speed reverse to Fast Jog 2. Set the parameter 05.04 Slow speed reverse strength to 100% Parameters: Parameter Description Setting range Default value Recommended Value 05.03 Slow speed reverse Sets the speed of the Pump cleaning reverse. It should be set to the maximum speed, which is 33% or the nominal motor speed. Fast jog, Jog, Creep Jog Fast jog 05.04 Slow speed rev strength Sets the torque for Pump cleaning reverse. It should be set to the highest possible, which is 100%. 10 ... 100% 50% 100% 4.4.2 08 Sequence start (pump cleaning forward) Menu u Parameters u Complete list u 08 Sequence start See Figure 15 for navigation. These are the recommended settings for Sequence start: 1. Set the parameter 08.01 Sequence mode to Start several motors 2. Set the parameter 08.02 Ie seq 1 to Rated current of the motor 3. Set the parameter 08.03 Start mode seq 1 to Full voltage start Parameters: Parameter Description Setting range Default value Recommended Value 08.01 Sequence mode Enables sequence start of motors which is necessary to have different starts for normal soft start of pump and Pump cleaning forward start. Off, Start several motors Off Start several motors 08.02 Ie seq 1 Sets the nominal current for the motor. For good performance, it is important that the nominal current is set to the correct value. For Inside Delta connection, this parameter shall be set to 58% of the nominal motor current. Depending on softstarter size Depending on softstarter size Rated current of the motor 08.03 Start mode seq 1 Sets the desired start mode for Pump cleaning forward. For maximum effect during the start select full voltage start. Voltage ramp, Tourque ramp, Full voltage start Voltage ramp Full voltage start 3
