4.3.2 Clock-direction
The controller internally sets the operating mode to clock-direction. You must connect the enable, clock and
direction inputs (see chapter X2 – digital inputs).
4.3.3 Analog speed
The controller internally sets the operating mode to Velocity. To preset the speed, the voltage on the analog
input is used and the corresponding target speed is written in 6042
.
4.3.3.1 Maximum speed
The maximum speed can be changed between 100 rpm and 1000 rpm. If a different speed is necessary, it
can be set using the scaling factor (object 604C

subindices 01
h
and 02
h
).
4.3.3.2 Computation of the analog voltage
There are two modes for calculating the analog input voltage.
Normal mode
You must connect the enable, direction and analog inputs (see chapter X2 – digital inputs). The
maximum analog voltage corresponds to the maximum speed. The direction is preset here via the
direction input. There is a dead zone from 0 V to 20 mV in which the motor does not move.

Joystick mode
You must connect the release input and the analog input (see chapter X2 – digital inputs). Half of
the maximum analog voltage corresponds to the speed 0. If the voltage drops below half, the speed
increases in the negative direction. If the speed rises above half, the speed increases likewise in the
positive direction. The dead zone here extends from U

/2 ± 20 mV.

4.3.4 Test run with 30 rpm
The motor rotates at 30 rpm if the enable input is set.
