YASKAWA TOEPYAIGA5002A GA500 DRIVE PROGRAMMING
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
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
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
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 %
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
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%
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
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 °
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
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
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
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 [ ]).
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Shows the fault history of the most recent fault.
Note:
The drive saves this fault history to two types of registers at the same time for the MEMOBUS/
Modbus communications.
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Shows the fault history of the second most recent fault.
Note:
The drive saves this fault history to two types of registers at the same time for the MEMOBUS/
Modbus communications.
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Shows the fault history of the third most recent fault.
Note:
The drive saves this fault history to two types of registers at the same time for the MEMOBUS/
Modbus communications.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Shows the fault history of the fourth most recent fault.
Note:
The drive saves this fault history to two types of registers at the same time for the MEMOBUS/
Modbus communications.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Shows the fault history of the fifth most recent fault.
Description
when the drive detects excessive current.
