Configuring the UDC Module’s Registers 3-29
I/O Status Register 201/1201
The bits in the I/O Status register indicate the current state of the inputs on the PMI.
Run Permissive Input Bit 0
The Run Permissive Input bit displays the
status of the input signal connected to pin A
on the DRIVE I/O connector. When the
signal is present, this bit is set. Hex Value: 0001H

The rum permissive input signal typically originates from the drive’s coast-to-stop
circuitry and is required to turn on the MCR output.
M-Contactor Feedback Bit 1
The M-Contactor Feedback bit reflects the
status of the M-contactor feedback input
signal, which is connected to the AUX IN1
input. When the input signal is present, this
bit is set. Hex Value: 0002H

Auxiliary Input 2 Bit 2
The Auxiliary Input 2 bit reflects the status of
the 115 VAC auxiliary input 2. When the
input signal is present, this bit is set. Hex Value: 0004H

Auxiliary Input 3 Bit 3
The Auxiliary Input 3 bit reflects the status of
the 115 VAC auxiliary input 3. When the
input signal is present, this bit is set. Hex Value: 0008H
Sug. Var. Name: AUX_IN3@
