15.6 Fixed reference values
The fixed reference values are to be parameterized as fixed frequencies or fixed percentages
according to the configuration and function.
The signs of the fixed reference values determine the direction of rotation. A positive sign means a
clockwise rotation, a negative sign means an anticlockwise rotation. The direction can only be
changed via the sign if the Reference Frequency Source 475 or Reference Percentage Source 476 is
parameterized to an operation mode with sign (+/-). The direction of rotation can also be stated
with the digital signal sources assigned to the parameters Start Clockwise 68 and Start
Anticlockwise 69.
The fixed reference values are to be parameterized in four data sets and are assigned to further
sources via the reference value channel. The use of the functions Data Set Change-Over 1 70 and
Data Set Change-Over 2 71 thus enables the setting of 16 fixed reference values.
15.6.1 Fixed frequencies
The four fixed frequencies define reference values which are selected via the Fixed Frequency
Change-Over 1 66 and Fixed Frequency Change-Over 2 67. The Reference Frequency Source 475
defines the addition of the various sources in the reference frequency channel.

Additional fixed frequencies can be selected if an optional extension module featuring
digital inputs is installed. In this case, follow the instructions on the optional extension
module.
15.6.2 JOG frequency
The JOG function forms part of the functions for controlling the drive mechanism via the control unit.
Use the arrow keys to change the JOG frequency within the function. The frequency of the output
signal is set to the entered value if the FUN key is pressed. The drive starts and the machine turns at
the set JOG-Frequency 489. If the JOG frequency has been changed using the arrow keys, this
value is stored.
