5.3 Description of Function Codes 5.3.5 H codes (High performance functions)
Forced operation (Fire Mode) (Run direction) (H119)
Sets the run command and rotation direction when forced operation (Fire Mode) is enabled.
Run/stop with run command (run command selected with F02) when performing
normal operation
* The motor does not run if the run command is OFF, but alarms are automatically
reset.
Operation in forward direction (FWD)
* The motor is forcibly rotated in the forward direction regardless of whether a run
command has been specified.
Operation in reverse direction (REV)
* The motor is forcibly rotated in the reverse direction regardless of whether a run
command has been specified.
Forced operation (Fire Mode) (Starting method) (H120)
Sets the starting method when forced operation (Fire Mode) is enabled.
Starting method when performing normal operation (starting method selected with H09,
d67)
Start-up in auto search mode (retracts without stopping motor while idling)
Forced operation (Fire Mode) (Wait time) (H121)
• Data setting range: 0.5 to 20.0 s (factory default: 5.0 s)
Sets the wait time until an automatic reset for inverter tripping while performing forced operation (Fire Mode).
For special adjustment (Torque limiting)
This function code is used to adjust the torque limiting responsiveness for a control method other than vector control.
Normally, it is not necessary to change the data of these function codes.
For special adjustment (Anti-regenerative control)
This function code is used to adjust the anti-regenerative control responsiveness. Normally, it is not necessary to
change the data of these function codes.
For special adjustment (Current limiting)
This function code is used to adjust the current limiting responsiveness for a control method other than vector
control. These are the control parameter for PMSMs. Normally, it is not necessary to change the data of these
function codes.
Speed control (Jogging) (Feed forward gain)
Refer to the description of d01 to d08.
