Chapter 7 FUNCTIONS


7.5 Compensation of secondary resistor function
(Temperature revision)

P025: Compensation of secondary

resistor selection

b098: Thermistor selection

b099: Thermistor error level

C085: Thermistor adjustment

Relation

Please use this function, if you want to do the temperature revision
to restrain the speed fluctuation by the temperature change of the
motor. (Please use the thermistor of the characteristic like type B
that shows it below. (This thermistor is the characteristic of
PE-41E made of a Shibaura electronics co.,Ltd.))
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.
