Functions, Setup and Operation
5.1
Start / Stop
There are two possibilities to start the spindle:
digitally
with a digital control signal at digital input1
Start/Stop
at SL2.1.
The switching levels for "OFF=0" are 0...7V and for "ON=1" 18...24V,
voltages between 7V and 18V are undefined.
As soon as this is initiated, the spindle will be accelerated to the set value of the
rotational speed which is pre-selected as voltage at analogue input1
Set Value of
Rotational Speed
at SL2.2.
analogue
with a voltage at analogue input1
Precondition is a valid "ON" signal at digital input1
Start/Stop
An input voltage of 0V makes the spindle stop, and a voltage higher than 0,29V
starts the spindle up to a rotational speed according to the scaling.
5.2
Set Value of Rotational Speed
There are two possibilities for scaling the rotational speed:
0-10V
/ Min-Max
: The default scaling for the analogue value is according the Min/Max
values of the rotational speed from the spindle characteristice.g.: set values are
Min: 5.000rpm, Max: 60.000
This results in a formula for the control voltage u: u = set value * 10V/60.000rpm
A voltage of u<0,8V realizes standstill, a voltage of 0,8V sets the minimum speed
of 5.000rpm and 10V sets the maximum rotational speed of 60.000rpm.
Another option of the input scaling
is
1V/10.000rpm
.
5.3
Outputs
Digital Outputs:
As feedback signals to a PLC or another control there are 3 open collector outputs available.
They indicate the current operational status of the converter. (
6.)
The functions can be setup freely, factory default is listed below
DO1 / SL2.9
default
Converter Ready
In this case, the PIN is drawn to ground
DO2 / SL2.7
default
Overload
In this case, the PIN is drawn to ground
DO3 / SL2.10 default
Duty speed reached
In this case, the PIN is drawn to ground
Analogue Output:
As a default function the output load condition is output as a voltage between 0..10V at the
analogue output AO / SL2.6. with a scaling of 1V/10% . Other function values are available
and can be setup with SFU-Terminal.
