Chapter 7 FUNCTIONS

7.5Compensation of secondary resistor function

(Temperature revision)
		Relation
Please use this function, if you want to do the temperature revision
	P025: Compensation of secondary
to restrain the speed fluctuation by the temperature change of the	resistor selection
motor. (Please use the thermistor of the characteristic like type B	b098: Thermistor selection
that shows it below. (This thermistor is the characteristic of	b099: Thermistor error level
PE-41E made of a Shibaura electronics co.,Ltd.))	C085: Thermistor adjustment

1.Please wire the thermistor that is built to the motor to the inverter.

(Wiring between TH and CM1 of the terminal unit board of the main body)

2.Please set up it as follows.

P025………01(valid) b098……… 02(NTC)

b099……….(This code is thermistor error level setting. Set the resistance value

of temperature for trip according to thermistor methods.) C085……….(Use this as gain adjustment.)

Figure 7-7 Resistor vs. Temperature Curves

(Note):Please wire it once again after the thermistor error occurrence level is changed, after you remove the wiring of the thermistor once, if the thermistor error occurred.
