U0-44
DI function state visual display 2
Default
--
Display Range
--
It displays whether the DI functions 41~59 are valid. The display format is similar to U0-42.
The 7-segment LEDs display functions 41–48, 49–56 and 57–59, respectively from right to left.
U0-46
Phase Z signal counting
Default
--
Display Range
--
It displays the phase Z counting of the present ABZ or UVW encoder. The value increases or decreases by 1 every
time the encoder rotates a round forwardly or reversely. You can check whether the installation of the encoder is
normal by viewing U0-45.
U0-47
Present setting frequency (%)
Default
--
Display Range
-100.00%~100.00%
U0-48
Present running frequency (%)
Default
--
Display Range
-100.00%~100.00%
It displays the present setting frequency and running frequency. 100.00% corresponds to the frequency inverter's
maximum frequency (b0-13).
U0-49
Frequency inverter running state
Default
--
Display Range
0~65535
It displays the running state of the frequency inverter. The data format is listed in the following table:
U0-49
Bit0
Bit1
0: stop
1: forwarder running
2: reverse running
Bit 2
Bit3
0: constant speed
1:acceleration
2:deceleration
Bit 4
0:Normal DC bus voltage
1:Low DC bus voltage
U0-50
Sent value of point-point communication
Default
--
Display Range
-100.00%~100.00%
U0-51
Received value of point-point communication
Default
--
Display Range
-100.00%~100.00%
It displays the data at point-point communication. U0-50 is the data sent by the master, and U0-51 is the data
received by the slave.
5.24 Group A0: System parameters
A0-00
User password
Default
--
Display Range
0~65535
If it is set to any non-zero number, the password protection function is enabled. After a password has been set and
