Risk of injury due to electric shock. After electric devices have been
switched off, touch volltages may occure.
1.2 Important Definitions
PC operation: The frequency inverter is configured and, if required, operated using a standard PC.
Micro step With a micro step start-up, the PMSM motor is operated as a synchronous motor with
– Start-up: constant current. In this case, the output frequency is slowly increased from 0 Hz to the
start-up frequency, after which the system switches to controlled motor running. With a
micro step start-up, it is possible to start up sensor less PMSM motors with large
centrifugal masses (such as vacuum pumps), which would otherwise fail to start due to the
large moment of inertia.
Ready for If no error occurs after the inverter switches on, then the green LED 1 lights up.
operation: This machine state is referred to as ready for operation.
Configuration: Configuration refers to the operating process that allows the settings of the frequency inverter
to be configured in relation to the motor data of the connected motor as well as the inputs and
outputs. The settings of the frequency inverter are configured with the help of the SycoDrive
operating software, which is available free of charge from the website www.sycotec.eu.
(A more detailed description of the SycoDrive operating software can be found in Chapter 9.0.)
