5.7 H: Terminal Functions
Setting 8, 9: Baseblock command
When the drive receives a baseblock command, the output transistors stop switching, the motor coasts to stop, and a bb
alarm flashes on the digital operator to indicate baseblock.

Setting F: Not used (Through mode)
Select this setting when using the terminal in a pass-through mode. When set to F, an input does not trigger any function
in the drive. Setting F, however, still allows the input status to be read out by a PLC via a communication option or
MEMOBUS/Modbus communications.
Setting 14: Fault reset
When the drive detects a fault condition, the fault output contact closes, the drive output shuts off, and the motor coasts to
stop (specific stopping methods can be selected for some faults such as L1-04 for motor overheat). After removing the
Up/Down command, clear the fault either by pressing the RESET key on the digital operator or closing a digital input
configured as a Fault Reset (И1-ПП = 14).
N ote: Rem ove the U p/D ow n comm and prior to resetting a fault. Fault Reset comm ands are ignored w hile the U p/D own comm and is
present.
Setting 15, 17: Fast Stop (N.O., N.C.)
The Fast Stop function operates similar to an emergency stop input to the drive. If a Fast Stop command is input while
the drive is running, the drive decelerates to a stop in the deceleration time set to C1-09
(Refer to C1-09: Emergency
Stop Ramp on page 145).
The drive can only be restarted after bringing the drive to a complete stop, turning off the Fast
Stop input, and switching off the Up/Down command.
• To trigger the Fast Stop function with a N.O. switch, set И 1-П П = 15.
• To trigger the Fast Stop function with a N.C. switch, set И 1-П П = 17.
