Using the SCANport Capabilities 8-15
To receive analog input from a SCANport device, you need to:
1. Set SP An In1 Sel (parameter 133) to the SCANport device
number.
2. Set the scale factor by using SP An In1 Scale (parameter 135).
3. Link a sink parameter to SP An In1 Value (parameter 134).
For example, if you plug a HIM into port 1 to control the external
speed, you need to enter a value of 1 for SP An In1 Sel and link Speed
Ref 1 (parameter 29) to SP An In1 Value. You may scale the speed by
using SP An In1 Scale or Speed Scale 1 (parameter 30).
The drive sends SP An Output (parameter 139) to all devices
connected to SCANport. To send data out to the SCANport devices,
link SP An Output to a source parameter. For example, if the HIM is
to receive speed feedback, you would link SP An Output to Motor
Speed (parameter 81).
When setting the scale factor, keep in mind the internal scaling range
of the SCANport device. For example, the HIM pot uses a range of 0
to 32767. Refer to the documentation for your SCANport device for
information about the range of the SCANport device.
