For the work of some machines, such as when starting and stopping, the rotor in the opposite direction of rotation will suddenly happen, this accident will cause extremely serious damage to the machine, so the recognition of reversal and parking protection is also an essential monitoring. VB-Z470B positive and negative rotation protection monitor on the machine axis of the reverse rotation identification and protection, is in the mechanical speed monitoring at the same time, it can receive two speed sensor input signal, the phase of the two signals provided by contrast and make direction judgment. Therefore, it has the function of speed monitoring and protection as well as reverse judgment and protection. It is a multifunctional monitoring instrument.
