Activating Inching Mode

By default "pulses" are used to issue a start command. This means that a start input has to change its logic level to issue a start
command - i.e. it is edge triggered. After the start command was accepted from the UMC the input signal can be set back to its ini-
tial value (e.g. zero). For a start signal sent from the digital inputs (DI4/DI5) it is possible to change the behaviour from pulse mode
to inching mode. This means that the motor is only running while the start signal is present. If it is not present anymore the motor
stops automatically.
