SW2 to 0–20mA 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 = 0.0Hz, PT100 function is disabled.
Example:
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".
