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:
1. Switch AFM to 0–20 mA on the control board.
2. Wiring:
– Connect external terminal AFM to “+”
– Connect external terminal ACM to “-“
– Connect AFM and AVI to “short circuit”
3. Pr.03-00 = 11, Pr.03-20 = 23, Pr.03-32 = 45% (9 mA)
4. See the RTD temperature and resistance comparison table
– Temperature = 135°C, resistance = 151.71 Ω, input current: 9 mA, voltage: about 1.37 V
DC
– Temperature = 150°C, resistance = 157.33 Ω, input current: 9 mA, voltage: about 1.42 V
DC
5. When the RTD temperature > 135°C, the drive decelerates to the specified operation frequency automatically.
Then, Pr.06-56 = 1.37 V and Pr.06-58 = 10 Hz. (When Pr.06-58 = 0, it disables the specified operation
frequency.)
6. When RTD temperature > 150°C, the drive outputs a fault, decelerates to STOP, and displays the warning
“oH3”. Then, Pr.06-57 = 1.42 V and Pr.06-29 = 1 (fault and ramp to stop).

When the drive detects that the unbalanced three-phase output current is higher than the setting for Pr.06-60, GFF
protection activates. The drive then stops output.
