P.350 and P.351 are used to set the encoder signal
which connects to the A1/B1 interface on PG03.
When the closed loop controls, the encoder signal for
feedback can only be connected to
the A1/B1 on
PG03.

<Setting>
• When the switch SW11 is set to PG, the terminal A2/B2 on PG03 card is valid.
• When using the PG card, P.350 and P.355 are applied for setting up the number of pulses
to be generated by the encoder per revolution of the motor. That is, the number of pulses
generated by one cycle of Phase A/Phase B. When carrying out PG feedback control, if
the detected frequency is 0, and with duration longer than the time set by P.352, and then
the PG card’s feedback signal is abnormal. The inverter will display alarm PG2 and stop
the operation. If PG signal abnormal (zero speed) detection time P.352 is set to 0, then
there is no PG card feedback signal abnormal function, i.e., no alarm PG2.
• When carrying out PG feedback control, if the difference between the detected frequency
and the output frequency exceeds P.353, and with duration longer than the set time
of P.354, then the speed deviation is too big. The inverter will display alarm PG3 and stop
the operation. If PG over-speed detection time P.354 is set to 0, then alarm PG3 function is
