Input Terminal Functions
îš‹ Temporarily Switching Operation between Digital Operator and
Control Circuit Terminals
The Inverter run command inputs and frequency reference inputs can be switched between Local and Remote.
• Local: The digital operator is used as frequency reference and run command source.
• Remote: The frequency reference and run command source can be set in the parameters b1-01 and b1-02.
If any parameter from H1-01 to H1-05 (Digital input terminal S3 to S7 function selection has been set to 1
(local/remote selection), this input can be used to switch over between local and remote.

îš‹ Inverter Output Baseblock
Using a baseblock command the inverter output can be stopped immediately. In this case the motor will coast
to stop. If the baseblock command is cleared, the inverter output operation is resumed.
If speed search is enabled, the inverter detects the motor speed and the operation is resumed from the detected
speed.
If speed search is disabled, the operation is resumed from the frequency reference which was active before the
baseblock command.
To use the baseblock function one of the digital inputs must be set for baseblock, i.e. H1-=8 (baseblock
command NO) or H1-=9 (baseblock command NC).
