1995. Parameter DescriptionEaton Electric General Inverters DF1 Series UMXXXXXXXXE February 2020 www.eaton.com5.10.3 PG abnormality detection• It is the detection standard when the abnormality occurrs in PG feedback control.Parameter Name FactoryValue Setting Range Content09-03P.352PG abnormality detectiontime 1.0s 0~100.0s PG wire-breakdetection time setting09-04P.353Over-speed detectionfrequency 4.00Hz 0~30.00Hz Motor over-speed detectionfrequencythreshold setting09-05P.354 Over-speed detection time 1.0s 0~100.0s Motor over-speed detection time setting09-16P.386DXF-ENC-302 Hard warebreak line detection 1 0 Break line detection is invalid1 Break line detection is effectivePG abnormality detection• When carrying out PG feedback control, if the detected frequency is 0, and with duration longer than the time setby 09-03, and then the PG card’s feedback signal is abnormal. The inverter will display alarm PG2 and stop the oper-ation. If PG signal abnormal (zero speed) detection time 09-03 is set to 0, then there is no PG card feedback signalabnormal function, i.e., no alarm PG2.• When carrying out PG feedback control, if the difference between the detected frequency and the output frequencyexceeds 09-04, and with duration longer than the set time of 09-05, then the speed deviation is too big. The inverterwill display alarm PG3 and stop the operation. If PG over-speed detection time 09-05 is set to 0, then alarm PG3function is not available.5.10.4 PG2 parameter• It is used to select the input mode of PG2 encoder.Parameter Name FactoryValue Setting Range Content09-06P.355Number 2 of the encoderpulses 2500 0~20000 It is used to set the encoder signal which connects to the A2/B2 interface on PG03.09-07P.356 Encoder input mode 2 00 No function1 Phase A/B pulse train, Phase A is 90° ahead of Phase B andis forward rotation.2 Phase A/B pulse train, Phase B is 90° ahead of Phase A andis forward rotation.3 Phase A is a pulse train. Phase B is a direction sign. L isreverse rotation and H is forward rotation.4 Phase A is a pulse train. Phase B is a direction sign. L isforward rotation and H is reverse rotation.PG2 parameter• When using the PG card, 09-06 is applied for setting up the number of pulses to be generated by the encoder perrevolution of the motor. That is, the number of pulses generated by one cycle of Phase A/Phase B.• Parameter 09-07is applied for setting up the encoder’s input mode.For the encoder’s input mode, please refer toparameter 09-02.• In speed mode, when 09-07 is not set to 0, the frequency command is the pulse input of A2/B2(targetfrequency(0.01Hz)=pulse frequency(Hz) /09-06*09-10); After the inverter starts, the actual rotation direction of themotor is determined by the value of 09-07, forward/reverse command and A2/B2 phases.• In position mode, when 09-07 is not set to 0, the position command is the pulse input of A2/B2(targetposition=A2B2 pulse number*09-10);After the inverter starts, the actual rotation direction of the motor is deter-mined by the value of 09-07, forward/reverse command and A2/B2 phases.
