Conversion
The different attributes for each parameter can be seen in the section
on factory settings.
Since a parameter value can only be transferred as a whole number,
a conversion factor must be used to transfer decimals.
Example:
Parameter 201: Minimum Frequency, conversion factor 0.1. If
parameter 201 is to be set to 10 Hz, a value of 100 must be trans-
ferred, since a conversion factor of 0.1 means that the transferred
value will be multiplied by 0.1. A value of 100 will, therefore, be
understood as 10.0.
Data Type
Data type shows the type and length of the packet.
The data types shown in the table are supported by the drive.
Unsigned means there is no sign included in the packet.
Control Word
The control word is used for transmitting commands from a master
(PC) to a slave (drive).

Data Type Table
Bit 00/01:
Bits 00 and 01 are used for choosing between the four pre-pro-
grammed references parameters 211 through 214, Preset Reference,
as shown in the table below.

Parameter 508, Choice of Preset Reference, is
used to choose how bits 00/01 are to be gated
with the corresponding functions of the digital
inputs.
Bit 02, DC BRAKE:
Bit 02 = 0 enables DC braking. Set braking current and duration in
parameter 114, DC Braking Current, and in parameter 115, DC
Braking Time.
Parameter 504, DC Brake, is used for selecting
how bit 02 is to be gated with the correspond-
ing function of terminal 27.
