9.2.2 Open-loop Control
In the “Control” mode, voltages of varying sizes or frequencies (if incre-
ments are used) with selectable magnitudes are specified and then used to
perform a controlled movement. The direction of movement is determined by
way of direction keys (R+ or R–).
The actual value of the axis is updated at the same time.
Note
A control, which may have been activated by a controller enable, will be
interrupted while the voltage/frequency is being output. After the Jogging
signals R+ or R– have died off, control is referred to the new actual value,
and reinstated after the axis comes to a stop, if the controller enable is still
active when the axis stops.
The voltage/frequency is defined with job No. 2.
You can choose between two mutually independent voltage/frequency values
(level 1 and level 2) with the mode parameter (BP).
Name Lower Input Limit Upper Input Limit Unit
Voltage (levels 1/2) 0 10 000 mV
Frequency (levels 1/2): 0 1 000 000 Hz
The values for the voltage levels can be changed during movement.
The table below gives you an overview of how to handle this mode.

BP = 1 Value of voltage/frequency level 1
“level-controlled”
BP = 2 Value of voltage/frequency level 2
Note
Please see also Section 9.1.3!
The control and checkback signals are handled in the same way as in “Jog-
ging” mode.
