· External thermal alarm (14)
HD IN OP
* 0 1 A 0
· The response is 0 if no alarm is detected.
· Refer to list of alarm codes for details of alarm numbers.
· F4006=1
HD IN OP
* 0 0 B 0
· The read data is a fixed floating-point value, with a same format
as the display on the operation panel of the inverter.
If a read error occurs, ―eXXXX‖ is returned as an error code.
·
See list of alarm codes for details of the error codes.
Refer to ―Note‖ for the read data format of F5001 (motor poles,
·
voltage and capacity).
· Output frequency: 50 Hz
HD IN OP
* 0 1 C 0
· The frequency data is multiplied by 100.
· Output current: 12[A]
HD IN OP
* 0 1 D 0
· The current data is multiplied by 10.
· DC voltage: 600V
HD IN OP
* 0 1 E 0
· The voltage data is multiplied by 10.
· Fin temperature: 50[℃]
HD IN OP
* 0 1 F 0
· The fin temperature data is multiplied by 1.
· Load factor: [40%]
HD IN OP
* 0 1 G 0
· The load factor data is multiplied by 1.
