To set the Grundfos RSI inverter for automatic start, activate the automatic fault reset function. Ensure that the STO (Safe Torque Off) inputs are energized. For safety, use an appropriate safety relay connected to the STO inputs to prevent unexpected restarts. Refer to the Application Manual for detailed configuration steps.

Page 119 P3.7.7 RampTimeFactor The Ramp time factor defines the acceleration/ deceleration time when the output frequency is in a prohibited frequency range. The Ramp time factor is multiplied with the value of parameters P3.4.1.2/ P3.4.1.3 (Ramp acceleration/deceleration time). For example the value 0.1 makes the acceleration/ deceleration time ten times shorter.

The information can also be programmed into any of the relay outputs.
Page 121 P3.9.2.4 ThermalTimeConst This is the thermal time constant of the motor. The bigger the motor, the bigger the time constant.

Page 123 P3.9.3.2 Stall Current The current can be set to 0.0…2*IL. For a stall stage to occur, the current must have exceeded this limit. See Figure 47. If parameter P3.1.3.1 Current Limit is changed, this parameter is automatically calculated to 90 % of the current limit. NOTE! In order to guarantee desired operation, this limit must be set below the current limit.
Page 124 P3.9.4.2 Fieldweak. Load The torque limit can be set between 10.0 - 150.0 % x TnMotor. This parameter gives the value for the minimum torque allowed when the output frequency is above the field weakening point. See Figure 48. If you change parameter P3.1.1.4 (Motor Nom Currnt) this parameter is automatically restored to the default value.

P3.9.4.4 Time Limit This time can be set between 2.0 and 600.0 s. This is the maximum time allowed for an underload state to exist. An internal up/down counter counts the accumulated underload time.
