YASKAWA TOEPYAIGA5001A GA500 DRIVE MAINTENANCE & TROUBLESHOOTING
Shows the status of the MFDO terminals at the most recent fault where
For example, U2-12 shows
Use U1-11 [Output Terminal Status] to monitor the actual MFDO terminal status.
bit0 : Terminal MA/MB-MC
bit1 : Terminal P1-C1
bit2 : Terminal P2-C2
bit3 : Not used (normal value of [ ]).
bit4 : Not used (normal value of [ ]).
bit5 : Not used (normal value of [ ]).
bit6 : Not used (normal value of [ ]).
bit7 : Not used (normal value of [ ]).
Shows the status of the MFDO terminals at the most recent fault where
For example, U2-13 shows
Use U1-12 [Drive Status] to monitor the actual MFDO terminal status.
bit0 : During Run
bit1 : During zero-speed
bit2 : During reverse
bit3 : During fault reset signal input
bit4 : During speed agreement
bit5 : Drive Ready
bit6 : During minor fault detection
bit7 : During fault detection
Shows the cumulative operation time of the drive at the fault that occurred most recently.
Use U4-01 [Cumulative Ope Time] to monitor the cumulative operation time.
Unit: 1 h
Shows the output frequency after soft start at the fault that occurred most recently.
Use U1-16 [SFS Output Frequency] to monitor the output frequency after soft start.
Unit: 0.01 Hz
Shows the q-Axis current of the motor at the fault that occurred most recently.
Use U6-01 [Iq Secondary Current] to monitor the q-Axis current of the motor.
Unit: 0.1 %
Shows the d-Axis current of the motor at the fault that occurred most recently.
Use U6-02 [Id ExcitationCurrent] to monitor the d-Axis current of the motor.
Unit: 0.1%
Shows the amount of control axis deviation (Δθ) at the fault that occurred most recently.
Use U6-10 [ContAxisDeviation Δθ] to monitor the actual amount of control axis deviation (Δθ).
Unit: 0.1 °
Shows the heatsink temperature at the fault that occurred most recently.
Use U4-08 [Heatsink Temperature] to monitor the temperature of the heatsink.
Unit: 1 °C
Monitors conditions to detect STPo [Motor Step-Out Detected] faults. The bit for each condition is
shown as = ON or = OFF.
For example, U2-21 shows
bit0 : Excessive current
bit1 : Induced voltage deviation
bit2 : d-axis current deviation
bit3 : Motor lock at startup
bit4 : Acceleration stall continue
bit5 : Acceleration stall repeat
bit6 : Not used (normal value of [ ]).
bit7 : Not used (normal value of [ ]).
Description
= ON and
when terminals MA and P2 are ON.
= ON and
during run.
when the drive detects excessive current.
