5.3 Description of Function Codes 5.3.2 E codes (Extension terminal functions)
EN terminal input OFF “ENOFF” assignment (Function code data = 102)
The signal comes ON when the EN terminal is turned OFF.
Braking transistor broken “DBAL” assignment (Function code data = 105)
If the inverter detects a breakdown of the braking transistor, it displays the braking transistor alarm (dba) and also
issues the output signal “DBAL”. Detection of the breakdown of a braking transistor can be canceled by H98.
( Function code H98)
A breakdown of the braking transistor could lead to a damage of the braking resistor or inverter’s internal
units. To prevent the secondary damage, use “DBAL” to cut off power to the magnetic contactor in inverter
primary circuits upon detection of a breakdown of the built-in braking transistor.
Customizable logic output signal 1 to 14 “CLO1” to “CLO14” assignment (Function code data = 111 to
124)
Outputs the result of customizable logic operation.
( Function code U codes)
Power consumption cumulative pulse “POUT” assignment (Function code data = 125)
A 0.15 s pulse is output each time the increase in integral power consumption increases by the unit electric energy
selected at function code E57.
( Function code E57)
Performing speed limiting “S-LIM” assignment (Function code data = 131)
Under vector control, the speed limiting function is enabled when performing droop control or torque control. This
signal turns ON if speed limiting occurs.
( Function codes H18, H28)
Performing torque limiting “T-LIM” assignment (Function code data = 132)
This signal turns ON if torque limiting occurs.
( Function code F40)
Dancer upper limit position warning signal “D-UPFL” assignment (Function code data = 135)
Dancer lower limit position warning signal “D-DNFL” assignment (Function code data = 136)
Dancer position limit warning signal “D-FL” assignment (Function code data = 137)
Signals are output when the dancer position reaches the set upper/lower limit warning position when performing
speed control (dancer) using PID control. Refer to the explanation on the following reference function code for
details.
( Function code J57)
Overtravel detection “OT-OUT”, Forced stop detection “STOP-OUT”, Pass point detection 1 “PPAS1”,
Pass point detection 2 (PPAS2) assignment (Function code data = 151 to 154)
These signals are for position control. Refer to the explanation on following reference function code for details.
( Function codes d201 to 299)
Overload detection “LLIM” assignment (Function code data = 158)
This signal is for the overload detection function. Refer to the explanation on following reference function code for
details.
( Function code d186)
Performing light load automatic double speed operation “LAC” assignment (Function code data = 159)
This signal is for the hoist function. Refer to the explanation on following reference function code for details.
( Function codes d170 to d189)
M/Shift key ON/OFF status “MTGL” assignment (Function code data = 251)
Indicates the ON/OFF status of the M/Shift key function assigned with function code E70.
