Calculating the external braking resistors
To achieve the highest braking effect, calculate the values of the resistors using the following
formula:
R
ext
n
max
Parameterization
You can parameterize the Motor Module and the Control Unit using the STARTER
commissioning tool. The expert lists of the drive objects and an input screen form to enter
the digital inputs/outputs are available.
The input screen form of the Control Unit for the digital inputs/outputs DI/DO 8 to 15 is
located under the "Control Unit/bidirectional digital inputs/outputs" window tab.
Terminals 11 and 14 are connected to ground.
The digital inputs/outputs DI/DO 8 to 15 are connected with terminals 9, 10, 12 and 13 at
terminal blocks X122 and X132. Parameters p0728[8...15] are used to define the terminals
as an input or output.
Digital inputs DI 8 to 15 are interconnected with the parameters p0722[8...15] and can be
inverted with p0723[8...15].
The outputs are interconnected with parameters p0738 to p0745.
The outputs can be inverted with p0748[8...15] = 1.
Parameters p0722 to p0748 are Control Unit parameters.
Parameters p123x, r1239 and r0046 are drive parameters.
