 PT100 operation instructions
Use voltage type analog input (AVI, ACI voltage 0–10 V) and select PT100 mode.
1.
Select one of the voltage type analog inputs below:
2.
(a) Pr.03-00 = 11
(b) Pr.03-01 = 11 and Pr.03-29 = 1
When selecting Pr.03-01 = 11 and Pr.03-29 = 1, you must switch AFM to 0–10 V.
3.
The AFM outputs constant voltage or current, then Pr.03-20 = 23. You must switch ACM to
4.
0–20 mA, and set AFM output level to 45% (Pr.03-32 = 45%) of 20 mA = 9 mA.
Use Pr.03-32 to adjust the constant voltage or constant current of the AFM output; the
5.
setting range is 0.00–100.00%.
There are two types of action levels for PT100. The diagram below shows the PT100
6.
protection action.
 When Pr.06-58 = 0.00 Hz, PT100 function is disabled.
Case:
When using PT100, if the motor temperature is higher than 135°C (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".
Set up process:
Switch AFM to 0–20 mA on the control board.

Wiring:
2.
Connect external terminal AFM to "+"
Connect external terminal ACM to "-"
Connect AFM and AVI to "short circuit"
Pr.03-00 = 11, Pr.03-20 = 23, Pr.03-32 = 45% (9 mA)
