9.7.2 Activation
The activation is not done via the object dictionary but a DIP-switch. For the settings of the switches
see chapter "DIP switches".
9.7.3 Accounting of analogue voltages
There are two modes of accounting of the analogue voltages. This mode is selected by the DIP switch
number 2 (see chapter "DIP switches").
Normal mode
DIP switch 2 "OFF": The maximum of the analogue voltage corresponds the maximal rotational
speed. The direction is set by the "direction" input. There is a dead-zone from 0 V to 20 mV in
which the motor doesn’t drive.

DIP switch 2 "ON": The half of the maximum analogue input voltage corresponds to the
rotational speed zero. If the input voltage falls below the half input voltage, the rotational speed
increases in negative direction. Accordingly if the input voltage increases over the half of the
input voltage the rotational speed increases in positive direction. The dead zone reaches from n

9.7.4 Maximum speed of rotation
The maximum speed of rotation can be switched with DIP-switch number 3 (see chapter "DIP
switches") between 100 rev/min and 1000 rev/min. In case another rotational speed is necessary the
maximums rotational speed can set in the configuration file and the object 604C
