External Brake 
ControlThe brake control function in the inverter contro ls external braking used in systems such as 
elevators. The purpose of this function is to en sure the inverter is powering the motor before 
releasing external brakes that would permit the load to move or coast. This function requires the 
configuration and wiring of intellig ent input and output terminals. See  “
External Brake Control 
Function” on page 4–32 for...

Overvoltage  
FunctionsB130/B131: Over-voltage LADSTOP Enable / Over-voltage LADSTOP Level –  The over-
voltage LADSTOP function monitors the DC bu s voltage and actively changes the output 
frequency profile to maintain the DC bus voltage  within settable limits. Although “LAD” refers 
to “linear acceleration / deceleration,” the invert er only “STOPs” the deceleration slope so that 
regenerative voltage will not cause the DC bus to rise enough to cause...

“C” Group: Intelligent Terminal Functions
The eight input terminals [ 1], [2], [ 3], [4], [ 5], [6], [7],  and [ 8] can be configured for any of 44 
different functions. The next two  tables show how to configure the eight terminals. The inputs 
are logical, in that they are either OFF or  ON. We define these states as OFF=0, and ON=1.
The inverter comes with default options for th e eight terminals. These default settings are...

NOTE: An input terminal configured  for option code 18 ([RS] Reset command) cannot be 
configured for normally closed operation.

Terminal 
OverviewEach of the eight intelligent terminals may be assigned any of  the options in the following 
table. When you program one of the option code s for terminal assignments C001 to C008, the 
respective terminal assumes the function role of  that option code. The terminal functions have a 
symbol...

Output Terminal 
ConfigurationThe inverter provides configuration for logic (d iscrete) and analog outputs, shown in the table 
below.
NOTE: *Terminals [11] – [13] or [11] – [14] ar e automatically configured as AC0 – AC2 or
AC0 – AC3 when C62 is configured to enable alarm code output.
The output logic convention is programmable fo r terminals [11] – [15], and the alarm relay 
terminals. The open-collector  output terminals [11] – [15] default to normally...
