Mains failure control (MFAIL)
This FB is used to decelerate the drive/drive network in a controlled manner to standstill. Without this
function, the drive/drive network would coast down after a mains failure.
Tip!
The basic configurations speed control with mains failure control (C0005 = 14xx) and digital
frequency master with mains failure control (C0005 = 54xx) are application examples which can be
directly loaded.
