2.1. Hardware
2.1.1. VLT Control Card Terminals
The terminals on the control card are allocated for positioning controller functions the following
parameter settings should therefore not be changed in synchronising mode (set-up 1):
Digital inputs 18, 19, 27, 32 and 33
Parameters 510–515 are set to
No operation
(default setting), then the inputs are ignored by the
control card but they are used as inputs for the positioning controller.
Analogue inputs 53, 54
Parameters 315, 316 and 317 are set to
No function
, then the inputs are ignored by the control
card but they are used as inputs to the positioning controller.
Digital/analogue outputs 42
Parameters 650 are set to:
MCO 0 … 20 mA [52] analogue output
