Connects PTC thermistor for motor protection.
Connect external resistor 1kΩ to terminal 13 - C1.
Used as additional auxiliary setting to various main settings of frequency.
Common for analog input/output signals (12, 13, C1)
Allowable maximum output current: 10mA
Input impedance: 22kΩ
Allowable maximum input voltage: 15V DC
If input voltage is +10V DC or over, the inverter
assumes it to be +10V DC.
Input impedance: 250Ω
Allowable maximum input current: +30mA DC
If input voltage is +20mA DC or over, the inverter assumes it to be +20mA DC.
Isolated from terminal CM and Y1E..
When FWD and REV are simultaneously ON,
the motor decelerates and stops. This function can
be set only for the terminals FWD and REV.
