 PT100 wiring diagram.
 Example:
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. Refer to the PT100 wiring
diagram for wiring.
2. Refer to 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
3. When the RTD temperature > 135°C, the drive decelerates to the specified operation
frequency automatically. Then, Pr.06-56 = 1.37 and Pr.06-58 = 10 Hz. When Pr.06-58 = 0, it
disables the specified operation frequency.
4. When RTD temperature > 150°C, the drive outputs a fault, decelerates to STOP, and displays
the warning “OH3”. Then, Pr.06-57 = 1.42 and Pr.06-29 = 1 (warn 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.
