Hi,
the Soft-Start function is enabled when the parameter 85.[riGr] is greater than 0 value. Function starts each time the device is switched on. The measure unit of the parameter 85 is Unit/Hour and this is risign gradient of the setpoint. For example if set it to 10 value, the device increase the setpoint 10 unit every hour, so if your setpoint is 100, it is need 10hour to reach it.

Best regards.
