• The set value of P.37 is the mechanical speed of the inverter when its output frequency is
60Hz.
For example: If the transmitting belt speed is 950 m/minute when the inverter output
frequency is 60Hz, P.37 shall be set to 950. In the “output frequency
monitoring mode” of DU01 operation panel, the screen will display the
speed of the transmitting belt.
Note: 1. There’s minute discrepancy between the displayed mechanical speed and the actual one.
2. Please refer to Section 4.1.2
for detailed operation of the “operation panel working mode.”
