(4) The AFM2 outputs constant voltage or current, then Pr.03-23 = 23. You must switch
AFM2 SW2 to 0–20 mA for the external I/O board, and set AFM2 output level to 45%
(Pr.03-33 = 45%) of 20 mA = 9 mA.
(5) Use Pr.03-33 to adjust the constant voltage or constant current of the AFM2 output; the
setting range is 0–100.00%.
(6) There are two types of action levels for PT100. The diagram below shows the PT100
protecting action.
(7) PT100 wiring diagram:

When Pr.06-58 = 0.00 Hz, PT100 function is disabled.
Case:
When using PT100, if the motor temperature is higher than 135ºC (275°F), the drive starts
to count the delay time for auto-deceleration (Pr.06-59). The drive decreases the motor
frequency to the setting for Pr.06-58 when it reaches the delay time count value. The drive
operates at the frequency set for Pr.06-58 until the motor temperature is lower than 135°C
(275°F). If the motor temperature is higher than 150°C (302°F), the drive automatically
decelerates to STOP and displays the warning “oH3”.
