5.4 Details of Function Codes
5-150
Assignment of Thermistor detected THM (Function code data = 56)
This function can output an alarm (THM) without setting an alarm
0h4
in the temperature detection by the
PTC thermistor of the motor and can continue the operation (Function code H26 = 2) (
Function code H26,
H27)
Assignment of Brake signal BRKS (Function code data = 57)
This function outputs an signal for brake release and activation. (
Function code J68 to J72)
Assignment of C1 terminal wire break detected C1OFF (Function code data = 59)
This function outputs an ON signal when the input of the terminal [C1] decreases to 2 mA or lower, and the
broken wire is judged.
Assignment of Speed valid DNZS (Function code data = 70)
This function outputs an ON signal when the speed command value/speed detect value is same or higher
than the stop speed set by the stop frequency. The signal turns off when the speed lower than the stop
speed continues for 100 ms or longer.
Under vector control with speed sensor, Function code F38 enables switching the decision criterion between
the sped command value and the speed detect value. In case of the speed sensor-less vector control, judge
by using the speed command value. (Function code F25, F38)

Assignment of Speed agreement DSAG (Function code data = 71)
This function outputs an ON signal to the output speed command of the acceleration/deceleration processor
while the deviation with the detected speed is within the set range. The signal turns off when the status is
beyond the set range for longer than the set period. This feature allows you to check whether the speed
controller is working correctly. (
Function code d21, d22)
Assignment of PG error detected PG-ERR (Function code data = 76)
When the operation continuation is set by the PG error and the PG error is detected, an alarm is not output,
and the operation continues. However, the ON signal is output as the PG error signal. (
Function code
d21 to d23)
Assignment of low medium voltage detected U-EDC (Function code data = 77)
When the DC medium voltage decreases to E76 "DC medium voltage detect level" or lower, this signal turns
on. When it increases to E76 or higher, the signal turns off. (
Function code E76)
