1.6 CONFIGURATION OF THE ANALOG AND DIGITAL INPUTS/OUTPUTS (I/O CONFIG)
The Drive, in its standard version on the regulation card, has at its disposal the following analog/digital I/Os:
3 analog inputs (terminals:1-2, 3-4, 5-6), configured as voltage or current differential inputs.
2 voltage analog outputs (terminals: 21-22-23), with a common reference potential.
8 digital inputs (terminals: 12-13-14-15, 36-37-38-39), with a common reference potential and a galvanic
isolation.
4 digital outputs (terminals: 41-42, 80-82, 83-85), with a common reference potential, a common power
supply and galvanic isolation.
NOTE! see chapter 1.3 in the Hardware Guide.
Other analog and digital I/Os are available by using the EXP…. expansion cards.
1.6.1 Analog Input Block (Analog Inputs)
The 2 Block sources allow to select the origin of the command signals for the following functions:
Analog input 1 sign src allows the inversion of the output signal, Analog input 1 alt sel src allows the selection
of an alternative output reference.
In the
configurations it is possible to perform the self-tuning of the offset and of the gain on the input, to modify
the input filter time constant, to set the input multiplicative factor (+1 or –1).
The upper and lower limit of the output signal can be set via the hi lim and lo lim parameters.
This function is shown in the figure of the following page.
· The Block has a sampling time of 2 msec. The resolution is: 10V=2047 counts.
The inputs of this Block are:
· Analog input 1 sign src
· Analog input 1 alt sel src
The outputs:
· Analog input 1 output
· Analog input 1 < thr
The following description of the parameters of the standard analog input 1 is valid also for the analog inputs 2 and 3.
