SIEPYEUOQ2A01A AC Drive Q2A Technical Manual
Description
Shows the fault that the drive has when viewing the monitor.
Shows the fault that occurred most recently.
Shows the frequency reference at the fault that occurred most recently.
Use U1-01 [Frequency Reference] to monitor the actual frequency reference value.
Unit: 0.01 Hz
Shows the output frequency at the fault that occurred most recently.
Use U1-02 [Output Frequency] to monitor the actual output frequency.
Unit: 0.01 Hz
Shows the output current at the fault that occurred most recently.
Use U1-03 [Output Current] to monitor the actual output current. The keypad shows
the value of U1-03 in amperes (A).
When looking at the monitor through Modbus communications, the current is "8192 =
drive rated current (A)". Calculate the current from the monitor value that is in at
Modbus communications using "Numerals being displayed / 8192 × drive rated current
(A)".
Unit: Determined by the drive model.
• 0.01 A: 4002 to 4023
• 0.1 A: 4031 to 4675
Shows the motor speed at the fault that occurred most recently.
Use U1-05 [Motor Speed] to monitor the actual motor speed.
Unit: 0.01 Hz
Shows the output voltage reference at the fault that occurred most recently.
Use U1-06 [Output Voltage Ref] to monitor the actual output voltage reference.
Unit: 0.1 V
Shows the DC bus voltage at the fault that occurred most recently.
Use U1-07 [DC Bus Voltage] to monitor the actual DC bus voltage.
Unit: 1 V
Shows the output power at the fault that occurred most recently.
Use U1-08 [Output Power] to monitor the actual output power.
Unit: 0.1 kW
Shows the torque reference at the fault that occurred most recently as a percentage of
the motor rated torque.
Use U1-09 [Torque Reference] to monitor the actual torque reference.
Unit: 0.1%
Shows the status of the MFDI terminals at the most recent fault where 1 = (ON) and 0 =
(OFF).
For example, U2-11 shows "00000011" when terminals DI1 and DI2 are ON.
Use U1-10 [In Terminal Status] to monitor the actual MFDI terminal status.
bit 0 : Terminal DI1
bit 1 : Terminal DI2
bit 2 : Terminal DI3
bit 3 : Terminal DI4
bit 4 : Terminal DI5
bit 5 : Terminal DI6
bit 6 : Terminal DI7
bit 7 : Terminal DI8
Shows the status of the MFDO terminals at the most recent fault where 1 = (ON) and 0
= (OFF).
For example, U2-12 shows "00000011" when terminals 2NO-2CM and 3NO-3CM are
ON.
Use U1-11 [Out Terminal Status] to monitor the actual MFDO terminal status.
bit 0 : Terminals 2NO-2CM
bit 1 : Terminals 3NO-3CM
bit 2 : Terminals 4NO-4CM
bit 3 : Not used (normal value of 0).
bit 4 : Not used (normal value of 0).
bit 5 : Not used (normal value of 0).
bit 6 : Not used (normal value of 0).
bit 7 : Fault relay 1NO/1NC-1CM
