Fan speed: indicates the current fan speed. This speed under normal conditions: environment within
the limits specified by the manufacturer and maximum pressure, such that the air flow remains at a
minimum value. A drop in the speed below certain values indicates an abnormal fan operation that
could lead the drive to an overtemperature fault or a fan speed fault:
• F174 - Left Fan Speed Fault,
• F175 - Central Fan Speed Fault,
• F176 - Right Fan Speed Fault
The indicated states are
• Normal: 0,85 x rated speed ≤ fan speed,
• Alert: 0,70 x rated speed ≤ fan speed < 0,85 x rated speed,
• Critical: if fan speed < 0,70 x rated speed
