Drive Event Flags (J70) indicates that certain actions have occurred within the drive as described below.
Bit 0: Defaults loaded
The drive sets bit 0 when defaults have been loaded and the associated parameter save has been completed. The drive does not reset this flag
except at power-up.
Bit 1: Drive mode changed
The drive sets bit 1 when the drive mode has changed and the associated parameter save has been completed. The drive does not reset this flag
except at power-up.
Thermal monitoring is provided within the drive to protect the power stage and the control system from over temperature.
Monitored Temperature 1 (J71), Monitored Temperature 2 (J72) and Monitored Temperature 3 (J73) give an indication of the temperature of three
selected monitoring points within the drive power system or control system. The required monitoring points can be selected using Monitor
Temperature Select 1 (J74), Monitor Temperature Select2 (J75) and Monitor Temperature Select 3 (J76) respectively. The default values give two
monitoring points in the power system in Monitored Temperature 1 (J71) and Monitored Temperature 2 (J72), and control board temperature 1 in
Monitored Temperature 3 (J73).
