Drive Configuration Chapter 1
Example Scenario
The drive has a HIM in port 1 and a 24V DC I/O module in port 5. You want to
select manual control from a digital input 3 on the I/O module. You want the
embedded EtherNet/IP port to be the source for the speed reference in
Automatic mode, and the HIM to be the source for the speed reference in
Manual mode.
Required Steps
1. Set P172 [DI Manual Ctrl] to Port 5-I/O Module > 1-Dig In Sts > 3 –
Input 3.
2. Set P328 [Alt Man Ref Sel] = 871 Port 1 Reference 3. Set P331 [Manual
Preload] = 0000 0000 0000 0010, Bit 1 enables the preloading of the
speed feedback value to the HIM at port 1 when the HIM is granted
manual control.
Digital Input Control
A Digital Input can be configured to request manual control through P172 [DI
Manual Ctrl]. When setting up the Auto/Manual masks, digital inputs are
configured through Bit 0, regardless of what port the module physically resides
in.
