<19> Display is in the following units.
 CIMR-U20028, 20042, and 40011 to 40027: 0.01 A units
 CIMR-U20054 to 20248, and 40034 to 40720: 0.1 A units
 CIMR-U40900, 40930: 1 A units
<23> When checking the values of U1-03, U2-05 and U4-13 with the digital operator they are displayed in units of amperes, but when they are
checked using MEMOBUS/Modbus communications, the monitor value in MEMOBUS/Modbus communications is: displayed numeric value
/ 8192 × drive' rated current (A), from the condition "8192 (maximum value) = drive' rated current (A)"
<26> The MEMOBUS/Modbus communications data is in 10 h units. If data in 1 h units are also required, refer to register number 0099H.
<58> The MEMOBUS/Modbus communications data is in 10 h units. If data in 1 h units are also required, refer to register number 009BH.

All Modes
Displays the frequency reference provided by MEMOBUS/Modbus (decimal).
All Modes
Displays the frequency reference input by an option card (decimal).
All Modes
Displays the source for the Run command as XY-nn.
X: Indicates which Run source is used:
1 = Reference 1 (b1-02)
2 = Reference 2 (b1-16)
Y: Input power supply data
0 = Digital operator
1 = External terminals
3 = MEMOBUS/Modbus communications
4 = Communication option card
7 = DWEZ
nn: Run command limit status data
00: No limit status.
01: Run command was left on when stopped in the PRG mode
02: Run command was left on when switching from LOCAL to REMOTE operation
03: Waiting for soft charge bypass contactor after power up (Uv or Uv1 flashes after 10 s)
04: Waiting for "Run command prohibited" time period to end
05: Fast Stop (digital input, digital operator)
06: b1-17 (Run command given at power-up)
07: During baseblock while coast to stop with timer
08: Frequency reference is below minimal reference during baseblock
09: Waiting for Enter command
All Modes
Displays the drive control data set by MEMOBUS/Modbus communications register no. 0001H
as a four-digit hexadecimal number.
All Modes
Displays drive control data set by an option card as a four-digit hexadecimal number.
