When in ‘monitoring output voltage’ mode, the screen will
display the value of the input signal across terminal 4-5
(mA/V).

When in ‘monitoring output voltage’ mode, the screen will
display the current thermal accumulating record for inverter.

● During the operation of PID control, the frequency displayed on the screen is the output frequency
of the inverter.
● The function of Stall Prevention operates according to the setting frequency before PID control.
Please pay attention to the Gain setting during the process of PID Gain setting in case that the
output current can not be limited absolutely.
● Under PID control, the output frequency is also limited between maximum frequency and
minimum frequency.
● Please refer to the instructions of P.60 about the input signal filter on terminal 4-5 and terminal 2-5.
