Shows the lower 4 digits of the drive run count.
Note:
The drive run count is an 8-digit number. Monitor U4-25 [Number of Runs(High)] shows the
upper 4 digits and U4-24 shows the lower 4 digits.
Shows the upper 4 digits of the drive run count.
Note:
The drive run count is an 8-digit number. Monitor U4-25 shows the upper 4 digits and U4-24
[Number of Runs (Low)] shows the lower 4 digits.
Shows the torque reference that the drive received from a serial communication option card or from
MEMOBUS/Modbus communications as a decimal number.
Unit: 0.1%
Shows the PID control feedback value. Parameter b5-20 [PID Unit Selection] sets the display units.
Unit: 0.01%
Shows the change between the PID setpoint and PID feedback (the quantity of PID input) as a
percentage of the maximum output frequency.
Unit: 0.01%
Shows the PID control output as a percentage of the maximum output frequency.
Unit: 0.01%
Shows the PID setpoint. Parameter b5-20 [PID Unit Selection] sets the display units.
Unit: 0.01%
Shows the PID differential feedback value as a percentage of the maximum output frequency.
Set H3-02 or H3-10 = 16 [MFAI Function Selection = Differential PID Feedback] to enable this
monitor.
Unit: 0.01%
Shows the difference from calculating U5-05 - U5-01 [PID DifferentialFdbk] - [PID Feedback].
Unit: 0.01%
Note:
U5-01 [PID Feedback] = U5-06 when H3-02 or H3-10 ≠ 16 [MFAI Function Selection ≠
Differential PID Feedback].
Shows the energy-saving coefficient Ki value for PM.
Unit: 0.01
Shows the energy-saving coefficient Kt value for PM.
Unit: 0.01
Shows the PID setpoint command. Parameter b5-20 [PID Unit Selection] sets the display units.
Unit: 0.01%
Shows the value calculated for the motor secondary current (q-Axis) as a percentage of the motor
rated secondary current.
Unit: 0.1%
Shows the value calculated for the motor excitation current (d-Axis) as a percentage of the motor
rated secondary current.
Unit: 0.1%
Shows the ASR input value as a percentage of the maximum frequency.
Unit: 0.01%
Shows the ASR output value as a percentage of the motor rated secondary current.
