Motor Thermistor Connection

Where a motor thermistor is to be used, it should be connected as follows:
Control Terminal Strip
5 CHECK
Switch Position
STOP
DI3 +10 DI4
AI2 VDC AI1
Open : Stop
Open : Forward Rotation
Open : Speed Reference set by Analog Speed Reference
Closed : Speed Reference set by Preset Speed 1 (P-20)
Sets the Speed Reference
NOTE For Switched units, the internal pot is selected by default in P-16.
For Non-switched units, an external pot or 0 - 10 V reference may be connected. Other
signal types may also be used, set P-16 to the correct format.
Additional Information
Compatible Thermistor: PTC Type, 2.5kΩ trip level.
 U se a setting of P-15 that has Input 3 function as External Trip,
e.g. P-15 = 3. Refer to online documentation for further details.
 Set P-47 = ""
