Description
3.8 Options
3.8.43
Redundant fan (option M61)
To increase the plant availability, the drive can be fitted with an additional, redundant fan. If a
fan in the drive cabinet fails, this is detected immediately by the electronic monitoring of the fan.
The redundant fan is connected by the drive controller without this causing the drive and, in
turn, the drive system to fail. This prevents production failures or interruptions. The
replacement of the defective fan can be postponed to the next planned stoppage.
3.8.44

60 Hz, 1.0 to 3.8 kW). The circuit breaker setting range is cos φ = 1 (8 A to 32 A).
