5.7.3 Using PTC
(1) Through an expansion card
（1） You can connect external PTC signal to terminal S8 through the expansion card EC-IO502-00,
and set the terminal function to 86 (PTC overtemperature signal is valid).
（2） You can set P92.21 to determine whether the VFD reports the alarm A-Ptc to run normally or
report PtcE to stop when the PTC overtemperature switch signal is valid.
Note: This function supports only terminal S8, the connected PTC acts at 2.5kΩ and supports
only dry-contact shared COM input.

(2) Through terminal AI1
Note: Turn SW2 on the control board to "I" for current output. Only AI1 and AO1 are supported
for PTC to measure temperature.
Procedure
-20.0–200.0° C
0: The PTC function is enabled through terminal
selection. When the PTC detected overtemperature
PTC alarm A-Ptc is reported, this cannot terminate
normal running.
1: The PTC function is valid through terminal
selection. When the PTC overtemperature fault PtcE
is reported, this results in stop.
86: Valid signal of PTC overtemperature
