Input Terminal Functions; Disable The Inverter Output (Baseblock) - Omron VARISPEED L7 Manual

Input Terminal Functions

The digital multifunction inputs can be set to several functions using the H1-01 to H1-05 parameters (terminal
S3 to S7 function selection). The following section describes the input functions not mentioned in any other
section.

Disable the Inverter Output (Baseblock)

Using a baseblock command the inverter output can be cut immediately. There are two baseblock functions
available, a hardware baseblock and a software baseblock.

8 External baseblock NO (NO contact: Baseblock at ON)
9 External baseblock NC (NC contact: Baseblock at OFF)
Hardware Baseblock
When hardware baseblock is activated, the power supply of the IGBT driver circuit is cut off and the motor
starts to coast. To use this baseblock function the digital input S8 must be used. The input is a NC input, i.e. if
terminal S8 is open, the inverter is base block condition.
Software Baseblock
When software baseblock is used, the inverter output is cut by a software function. To use this baseblock func-
tion one of the digital inputs must be set to baseblock, i.e. one of the parameters H1-01 to H1-05 (digital input
terminal S3 to S7 function selection) must be set to 8 or 9 (Baseblock command NO/NC). The input can be
used with a NC as well as with a NO contact.
Baseblock Restart Behavior
If baseblock is activated, the inverter output is immediately stopped. Using parameter S1-12 it can be selected,
whether the Up/Down command input has to be cycled to restart when the baseblock is disabled or not.
