PG error detection
When executing PG feedback control, if detected frequency is 0,and over the set time of 09-03(
P.352
),it should be
determined as error of PG card`s feed back signal. Inverter will display alarm PG2 and end operation. If PG signal
error(zero speed)detection time 09-03(
P.352
) is 0，then no PG card feedback signal error function,i.e.,no alarm
PG2.
When executing PG feedback control，if different between detected frequency and output frequency is over
09-04(
P.353
)，and over the time set of 09-05(
P.354
)，the speed deviation should be determined as too fast. Inverter
will display alarm PG3 and end operation. .If PG Over-speed detection time 09-05(P.354) is set to 0,then no alarm
PG3 function.
PG302Lhardware disconnection detection function （09-16(P.386) one-digit）effective to PM/IM motors，A1/B1
phase sequence detection function（09-16(P.386) two digits）only effective to IM motor
