3-5 Monitoring the Rotational Speed by Monitor
Output of an Inverter
(K3MA-F)
Application
• The K3MA-F monitors the rotational speed by monitor output of an inverter.
• The monitor output of the inverter produces a voltage pulse proportional to the
rotational speed of the motor. When the rotational speed of the motor is 60 rps, it
produces 1440 Hz.
• The unit of indicated values by the K3MA-F is "rpm".
• When the rotational speed reaches 3000 rpm, comparative output 1 is turned ON.
• When the rotational speed decreases to 2000 rpm, comparative output 2 is turned
ON.
