Input Terminal Functions
The digital multifunction inputs can be set for several functions using the H1-01 to H1-05 parameters (termi-
nal S3 to S7 function selection). These following section describes the input functions not mentioned in any
other section.
Related Parameters
Blocking Inverter Outputs (Hardware Baseblock)
Using a baseblock command the inverter output can be cut immediately. When baseblock is activated the
power supply of the IGBT driver circuit is cut off. In this case the motor will start coasting. If the baseblock
command is cleared, the inverter output operation is resumed.
To use the baseblock function one of the digital input S8 must be used. The input is a NC input, i.e. if terminal
S8 is open, the inverter is baseblocked.
Stopping the Inverter on External Device Errors (External Error Function)
The external error function activates the error contact output and stops the Inverter operation. Using this func-
tion the inverter operation can be stopped on peripheral devices break down or other errors. The digital opera-
tor will display EFx (External error [input terminal Sx]). The x in EFx shows the number of the terminal at
which the external error signal is input. For example, if an external error signal is input to terminal S3, EF3
will be displayed.
To use the external error function, set one of the values 20 to 2F in one of the parameters H1-01 to H1-05 (dig-
ital input terminal S3 to S7 function selection).
Select the value to be set in H1-01 to H1-05 from a combination of any of the following three conditions.
•
Signal input level from peripheral devices
•
External error detection method
•
Operation after external error detection
