7.5 Compensation of secondary resistor function
(Temperature revision)
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)
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.)
(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.
b098......... 02(NTC)
