Set up process:
1. Switch AFM2 to 0–20 mA 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, Pr.03-23 = 23 or Pr.03-33 = 45% (9 mA)
4. Refer to the RTD temperature and resistance comparison table
Temperature = 135ºC, resistance = 151.71 ; input current: 9 mA, voltage: about 1.37 V
DC
Temperature = 150ºC, resistance = 157.33 ; input current: 9 mA, voltage: about 1.42 V
DC
5. When the RTD temperature > 135ºC, 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 the RTD temperature > 150ºC, 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).

06-60
Software Detection GFF Current Level
Default: 60.0
Settings 0.0–200.0%

06-61
Software Detection GFF Filter Time
Default: 0.10
Settings 0.00–655.35 sec.
 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.

06-62
dEb Reset Bias Level (Applied to 230V / 460V Models)
Default:
Settings 230V models: 0.0–100 V
DC
20.0
460V models: 0.0–200.0 V
DC
40.0
 Prevent action vibration caused by dEb action level = reset level. dEb active level + Pr.06-62 =
dEb reset bias level.

Operation Time of Fault Record 2 (Days)
Default: Read only
Settings 0–65535 days
06-67
Operation Time of Fault Record 3 (Days)
Default: Read only
Settings 0–65535 days
