03-0X =30: Acceleration/ Deceleration Setting Command 2
When it is ON, the inverter will be active depends on the acceleration time 2 of 00-16 and deceleration time
2 of 00-17.
03-0X =31: Inverter overheat warning
When input is active the inverter displays warning message "OH2" and continues operation. Deactivating
the input reverts back to the original display. Warning message does not require resetting the inverter.
03-0X =33: DC braking
When input is active DC-Injection braking is enabled during start and stopping of the inverter.
DC Injection braking is disabled when a run or jog command is active.
Note: Either short-circuits braking command or DC braking command is selected. If these two modes are
both selected, SE02 error (DI Terminal Error) will occur.
Refer to the DC braking time diagram in Fig.4.4.21.

03-0X =35: Timing function
Refer to the "time function" parameter 03-37 and 03-38.
03-0X =36: PID Soft start disable
Refer to the "PID Control" function of PID function parameter group 10.
03-0X =47: Fire mode (Foreced to operation mode)
When input is active disables all inverter warning and hardware (exclusive of SC) protections. This function
is commonly used in commercial applications where the inverter controls an exhaust fan and needs run to
destruction in case of a fire.
03-0X =48: KEB acceleration
When input is active enables KEB (Kinetic Energy Braking) during acceleration. Refer to the parameter
description of 11-47 and 11-48. Note: To enable set parameter 11-47 to a value greater than 0.
03-0X =49: Parameters write-in allowed
When input is active allows parameter to be changed.
Note: When none of the digital input terminals are set to function 49, parameter write-in protection is
controlled by parameter 13-06.
