selected as dened in this
table
Note:
1. 1. When PTC motor thermistor is used, 1304 must set to "PTC-th" mode. Otherwise digital input 3 will be used as external trip input (digital
level sensitive). When 1304 is set to "PTC-th", drive will display code "F-Ptc" if thermistor value is larger than 2.5kohm. The trip can only be
reset if the thermistor value drops below 1.9kohm. Thermistor must be connected between terminal 1 (24V DC) and terminal 4 (2nd analog
input). If 1304 is set t other value, the input will be used as external trip trigger input and drive will display code "E-trp" instead if the input is
open.
"E-trp" only happens when drive is enabled (running), however thermistor trip can happen at any time.
