5.3 Description of Function Codes
5-124
■
Speed agreement -- “DSAG” (Function code data = 71)
This output signal comes ON when the deviation of the detected speed from the speed command after the
acceleration/deceleration processor is within the allowable range specified by d21. It goes OFF when the deviation
is beyond the range for longer than the period specified by d22. This feature allows you to check whether the
speed controller is working correctly.
Function codes d21 and d22.
■
PG error detected -- “PG-ERR” (Function code data = 76)
This output signal comes ON when the inverter detects a PG error with the d23 (PG error processing) data being
set to “0: Continue to run,” in which the inverter does not enter the alarm state.
Function codes d21 through d23.
■
Low DC link bus voltage detection – “U-EDC” (Function code data = 77)
This output signal comes ON when the DC intermediate voltage drops below E76 (DC link bus low-voltage
detection level), and it goes OFF when the DC intermediate voltage exceeds E76. (
Function code E76)
■
During decelerating at momentary power failure – “IPF2” (Function code data = 79)
When F14 data is set to 2 or 3, this output signal comes ON when the DC intermediate voltage drops below H15
(Continue to run level) and continue to run control starts. When the power returns and the DC intermediate voltage
becomes “at least 10 V higher than the voltage specified by H15,” the signal goes OFF.
Even when F14 data is set to 4 or 5, the signal comes ON when the DC intermediate voltage drops below the
undervoltage level, and it goes OFF when the DC intermediate voltage becomes “at least 10 V higher than the
undervoltage level.” (
Function codes F14 and H15)
■
The positioning control signals -- “OT”, “TO” and “POF” (Function code data = 80, 81, 83)
These signals are used to the positioning control function. (
Function codes J73 to J88)
■
Positioning completed -- “PSET” (Function code data = 82)
This output signal comes ON as a positioning completion signal. This signal is used to the servolock function and
the positioning control function.
(
Function codes to J97 to J99 for the servo lock function, function codes J73 to J88 for the positioning control
function)
■
Maintenance timer counted up – “MNT” (Function code data = 84)
Once the inverter’s cumulative run time or the startup times for the motor 1 exceeds the previously specified count,
this output signal comes ON. (
Function codes H78 and H79)
