reported. The charging relay may be damaged or the grid voltage is suddenly
decreased.
The Fault No 114 reported due to insufficient capacity of temporary power supply
adopted at the beginning of on-sit adjustment and setting. Meanwhile, it is impossible
to improve the capacity of power supply at the working place. Under such
circumstance, users can confirm that the charging relay of frequency converter is ok if
they can hear the sound of relay close and open inside of frequency converter when
the frequency convert is power-on or power-off. Then users can realize this kind of
the elevator running with the temporary power by changing the parameter of the
frequency converter. The detailed method is as follow:
Change the parameter F253 from default value 45 to 90. In this way the elevator can
run with low-capacity power supply. When the on-site installation is completed,
change the parameter value back to the default value of 45 when the normal power
supply is recovered.
F254—— encoder CD phase fault confirmation threshold. The default value is 300. When the
difference value between the encoder absolute position and calculation position
exceed the setting value, the No.28 fault reported.
When selecting not to do self-study with power on (F245=6, F246=0). The integrated
unite will automatically activate the encoder C/D phase inspection. If it is found that
C/D phase position is not correct, the setting threshold of F254 exceed, the integrated
unit will report No 98 default.
Please note the if value F245 (F245=6) change from 1 to 0 on the site, the No 98 fault
will reported, because C/D phase position is not inspected when F245=1(F245=6),and
disconnection or wrong connection does not matter. The fault inspection is only for
sincos encoder and Endata encoder.
F255—— ABZ encoder disconnection protection threshold. The default value is 20%. When the
synchronous motor adopted the ABZ encoder, the encoder disconnection is identified
once the feedback speed deviation exceeds the protection threshold. The No 12 fault
is reported with the frequency converter.
When F245=1
F246---- Times og Instantaneous overcurrent of IGBT
F247---- 0:two ways of I2t protection,1:only the first way of I2t protection,2: only the second way
of I2t protection
When F245=2
F247—— PWM adjustment mode. 0: 5 stages, 1: 7 stages, 2: <40%rpm 7stages, >40% 5 stages.
The integrated units at low-speed cause too much interference to outside. For example,
change to 0 (5 stages) for the improvement of CAN communication signal and for
heating reduction of frequency converter. But in this way will possible cause the loud
noise of frequency converter at low speed.
F250—— three phase current balance coefficient. This parameter is read-only parameter; it will
change automatically after doing the three-phase electricity balance coefficient
calibration. If it is synchronous motor, activation of synchronous motor self-study
command will close the output contactor and conduct the three-phase current
calibration. This function will reduce the motor vibration and improve the comfort.
