Other inputs
z
MB-FREE input (Available for only drivers for electromagnetic brake motor)
This input signal can be used to operate whether the electromagnetic brake holds or releases while the motor stops.
When this input is turned ON at motor standstill, the electromagnetic brake is released to bring the motor shaft in a free-run
state.
Even if the "Load holding function selection" parameter is set to enable, when the MB-FREE input is turned ON, the motor shaft
will be in a free-run state.
You cannot operate to release the electromagnetic brake while an alarm is being generated.
z
H-FREE input
This input signal can be used when the load holding function is enabled.
If the H-FREE input is turned ON when the stopped motor shaft is electrically held by the load holding function, the motor shaft
can be in a free-run state.
In the case of the drivers for electromagnetic brake motor, if the H-FREE input is turned ON while the motor shaft is held by the
load holding function, the motor excitation is turned OFF, and the electromagnetic brake holds the motor shaft.
z
TL input
The TL input is normally closed.
When the TL input is turned ON, the torque limiting function is enabled.
The motor output torque is limited based on the set torque.
When the TL input is turned OFF, the torque limiting function is disabled, and the maximum value of the motor output torque
will be the peak torque.
z
INFO-CLR input
The INFO-CLR input is a signal to clear an information status. (Information will be cleared at the ON edge of the input.)
This signal can be used when the "INFO auto clear" parameter is set to disable, and the information status will be cleared when
the signal is turned ON.
z
HMI input
The HMI input is normally closed.
When the HMI input is turned ON, the function limitation by the operation panel or
MEXE02
is released. When the HMI input is
turned OFF, the function limitation is imposed.
[Functions to be limited]
•
I/O test
•
Local control operation
•
Teaching/remote operation
•
Editing parameters and data, downloading, initializing
•
Conguration
z
EXT-ERROR input
The EXT-ERROR input is normally closed.
When this signal is turned OFF, an alarm is generated, and the motor stops instantaneously.
Then "
" is shown on the display.
Note
When the HMI input, TL input, and EXT-ERROR input are not assigned to input terminals, they are always set to ON.
And if a single input is assigned to multiple input terminals, the function will be performed when all of the terminals
are turned ON.
