If parameter 620 = 0, then the Reset input requires a N.O. pushbutton as shown above. Closing the
pushbutton causes System Reset to occur. This is the default value for the 1395.

*

If parameter 620 = 1, then the Normal Stop input requires a N.C. pushbutton as shown above.
Opening the pushbutton causes Normal Stop to occur.

Refer to Table 6.L

** If no thermostat is used, 115VAC or 24VDC must still be applied to TB3 terminal 2.

NOTE: If N.C. is used, and 620 = 0, Drive will be in a continuous reset condition.
If N.O. is used, and 620 = 1, A Stop will be present in Logic Cmd 1 Par.150
