<1> The MEMOBUS/Modbus communications data is in 10 h units. If data in 1 h units are also required, refer to register number 0099H.
<2> The MEMOBUS/Modbus communications data is in 10 h units. If data in 1 h units are also required, refer to register number 009BH.
<3> Display is in the following units:
2A0004 to 2A0040, 4A0002 to 4A0023, and 5A0007 to 5A0017: 0.01 A units.
2A0056 to 2A0415, 4A0031 to 4A0675, and 5A0022 to 5A0242: 0.1 A units.
4A0930 and 4A1200: 1 A units.
<4> The values of U1-03, U2-05, and U4-13 are displayed on the digital operator in units of amperes. When those monitors are checked using
MEMOBUS/Modbus communications, the monitor values in MEMOBUS/Modbus communications are displayed as: numeric value / 8192 × drive
rated current (A) from the condition "192 (maximum value) = drive rated current (A)"
<5> When reading the value of this monitor via MEMOBUS/Modbus a value of 8192 is equal to 100% of the drive rated output current.

LCD Display
Displays the PID feedback value.
PID Feedback 1
Displays the amount of PID input (deviation between PID
PID Input
setpoint and feedback).
Displays PID control output.
PID Output
Displays the PID setpoint.
PID Setpoint
Displays the 2nd PID feedback value if differential feedback is
PID Feedback 2
used (H3-oo = 16).
Displays the difference of both feedback values if differential
feedback is used (U5-01 - U5-05). If differential feedback is
not used, then U5-01 and U5-06 will be the same.
Displays the energy saving coefficient Ki value.
Ki Auto Cal Val
Displays the energy saving coefficient Kt value.

LCD Display
Displays the value of the motor secondary current (Iq). Motor
rated secondary current is 100%.
Mot SEC Current
Displays the value calculated for the motor excitation current
(Id). Motor rated secondary current is 100%.
