Instruction
Code
H7B H0000: Network operation
H0001: External operation
HFB
H0002: PU operation
H0000 to HFFFF: Rotation speed in 1r/min increments
Output frequency increments 0.01Hz (when Pr.144 = 10 (2, 4, 6, 8))
H6F Machine speed increments 0.001 (when Pr.37 = 0.01 to 9998)
When "100" is set in Pr.52, the monitor value is different depending on
whether the drive unit is at a stop or running. (Refer to page 155)
H70 H0000 to HFFFF: Output current (hexadecimal) in 0.01A increments
H71 H0000 to HFFFF: Output voltage (hexadecimal) in 0.1V increments
H72 H0000 to HFFFF: Monitor data selected in instruction code HF3
H73
H01 to H3F: Monitor selection data
Refer to the special monitor No. table (page 218)
HF3
H0000 to HFFFF: Two latest fault records
H74 to H77
Refer to the alarm data table (page 219)
HF9
Control input commands such as the forward rotation signal (STF) and
reverse rotation signal (STR). (For details, refer to Refer to page 219)
HFA
H79 Monitor the states of the output signals such as forward rotation, reverse
rotation and drive unit running (RUN). (For details, refer to Refer to page
H7A
220)
Read the set frequency/speed from RAM or EEPROM.
H6D

H6E
Machine speed increments 0.001 (when Pr.37 = 0.01 to 9998)
Write the set frequency/speed to RAM or EEPROM.
HED
H0000 to HFFFF: speed setting increments 1r/min.
Setting frequency increments 0.01Hz (when Pr.144 = 10 (2, 4, 6, 8))
Machine speed increments 0.001 (when Pr.37 = 0.01 to 9998))
 To change the set speed/frequency consecutively, write data to the drive
HEE
unit RAM. (Instruction code: HED)
