Operation as slave drive.
For traverse mode, the reference value source is selected via parameter Reference Frequency 48.
Traverse mode becomes active once the Reference Frequency 48 is reached for the first time. This
frequency is reached via the values for Acceleration (Clockwise) 420, Acceleration Anticlockwise
422, Deceleration (Clockwise) 421 and Deceleration Anticlockwise 423. In traverse mode, the
values for Acceleration Time 436 and Deceleration Time 437 are active.
The frequency range for traverse mode is limited by Minimum Frequency 418 and Maximum
Frequency 419.
During traverse operation, the configured traverse parameter values cannot be changed.
The source of the handshake signal is selected via Handshake Traverse Function 49.
19.9 Profibus/Internal Notation converter
With the Profibus/Internal Notation converter (“Convert Profibus/Intern”), you can convert a 16 bit
word to an internal 32 bit frequency value and vice versa. This is useful, for example, if several
devices are networked via System Bus and only 1 device is provided with a Profibus option for cost
reasons. By forwarding the Profibus word via System Bus (“Tunneling”), you can reduce the
bandwidth needed in System Bus and make parameterization of the “Gateways” (System Bus Master
with Profibus Slave communication module) easier. In this case, the converter is used without
Profibus module in one device in order to convert the Profibus notation to an internal reference
value.

Likewise, the current frequency can be converted to a value based on Profibus notation, for
example.
The converter can also be used for other purposes, e.g. using the internal PLC programming.
In-F-PDP-word 1 1370 and In-F-PDP-word 2 1371 convert Profibus notation to internal frequency
representations. 0x4000 in Profibus notation (=100 %) corresponds to In-F-Convert
Reference 1374 in Hz.
In-F-intern-long 1 1372 and In-F-intern-long 2 1373 convert internal frequency values to Profibus
notation. 0x4000 in Profibus notation (=100 %) corresponds to In-F-Convert Reference 1374 in Hz.
Profibus notation is limited to values from -200 % (0x8000) to +200 % (0x7FFF).
