Operation with zero-speed control

Zero-speed control may serve as a protective function which can also be
used if two identical motors are operated by one inverter.
For activating zero-speed control, activate parameter P20.
If the FG enable signal had been activated before, first cycle power to the
unit, then activate P20.
DANGER
Zero-speed control is guaranteed only if the motor is standing when
monitoring is switched on!
