When Pr.06-58=0.00Hz, PT100 function is disabled.
Example:
A PT100 is installed to the drive. If motor temperature reaches 135 (275°F) or higher, the drive
will decrease motor frequency to the setting of Pr.06-58. Motor will operate at this frequency
(Pr.06-58) till the motor temperature decreases to 135(275°F) or lower. If motor temperature
exceeds 150(302°F), the motor will decelerate to stop and outputs an ‘OH3’ warning.
Set up process:
1. Switch AFM2 (SW2) to 0-20mA on the I/O control terminal block. (Refer to Figure 1, PT100 wiring
diagram)
2. Wiring (Refer to Figure 1, PT100 wiring diagram):
Connect external terminal AFM2 to (+)
Connect external terminal ACM to (-)
Connect external terminals AFM2 and AVI to short-circuit
3. Set Pr.03-00=11 or Pr.03-23=23 or Pr.03-33=45%(9mA)
4. Refer to RTD temperature and resistance comparison table
Temperature=135 , resistance=151.71; Input current: 9mA, Voltage: approximately: 1.37Vdc
Temperature=150 , resistance=157.33; Input current:9mA, Voltage: approximately: 1.42Vdc
5. Set Pr.06=56=1.37 and Pr.06-58=10Hz. When RTD temperature increases to 135 or higher,
the drive will decelerate to the selected frequency. When Pr.06-58=0, the drive will not run.
6. Set Pr.06-57=1.42 and Pr.06-29=1 (warning and decelerate to stop). When RTD temperature
increases to 150 or higher, the drive will decelerate to stop and outputs an OH3 warning.

When the motor drive detects the unbalanced three-phase out current is higher than the setting of
Pr06-60, GFF protection will be activated. Then the motor drive will stop outputting.
