Remark:
*1: Models IP20 200V 5~30HP, 400V 5~40HP and IP55 400V 5~25HP have a built-in braking transistor so that the braking resistor can be connected between
terminal B1 and B2.
*2: The multi-function digital input terminals S1~S6 can be set to Source (PNP) or Sink (NPN) mode via SW3.
*3: The multi-function analog input 2 (AI2) can be set to the voltage command input (0~10v) or the current command input (4~20mA) via SW2.
*4: Run permissive input F1 & F2 is a normally closed input. This input should be closed to enable the inverter output. To activate this input, open the link
between F1 and F2.
