Chapter 5 Detailed Function Introductions
Pd.12 Input Phase Loss Detection Benchmark
Pd.13 Input Phase Detection Time
Notes:

With this function, the input phase loss or the serious imbalance of the input three phases can be detected to
protect the frequency inverter. If the input phase loss protection is too sensitive, the detection benchmark
Pd.12 and the detection time Pd.13can be increased appropriately. If it is not so sensitive, the detection
benchmark Pd.12 and the detection timePd.13 can be reduced.
Pd.14 Output Phase Loss Detection Benchmark
Pd.15 Output Phase Detection Time
Notes:

With this function, the output phase loss or the serious imbalance of the output three phases can be detected to
protect the frequency inverter and motor. If the output phase loss protection is too sensitive, the detection
benchmark and the detection time can be increased appropriately. If it is not so sensitive, the detection
benchmark and the detection time can be reduced.
Pd.16 Enabling keypad keys UP/DN
0: Invalid
Notes:
 In the case the digital encoder is damaged, the function can be set as 1 to enable the keypad key UP/DN
manner. The keypad key JOG acts as the UP key and the direction key acts as the DN key
 or via the combination key: the function can be enable by pressing the keys Shift +JOG for 5s (this manner
can only be set and effective when the function group is displayed, and will not be saved after power down)
Pd.16 Enabling keypad keys UP/DN
0: Invalid
Notes:
 With this function, it can be set whether the alarm will be displayed in the case of abnormal analog signal;
when it is set as 1, if the analog signal 1/2/3 is abnormal, the alarm AE1/AE2/AE3 will be displayed; when it
is set as 0, the alarm will not be displayed.
