Feedback Power Supply Specifications
The IAM and AM power circuit board generates +5V and +9V DC for motor
and auxiliary feedback power. Short circuit protection and separate common
mode filtering for each channel is included.
Parameter Description Min Max
AM, BM, and IM
On-state input voltage
Input voltage difference between the plus (+) input and
the minus (-) input that is detected as an on-state.
+1.0V +7.0V
AM, BM, and IM
Off-state input voltage
Input voltage difference between the plus (+) input and
the minus (-) input that is detected as an off-state.
-1.0V -7.0V
Common mode
input voltage
Potential difference between any encoder signal and
logic ground.
-7.0V +12.0V
DC current draw Current draw into the + or - input. -30 mA 30 mA
AM, BM input
signal frequency
Frequency of the AM or BM signal inputs. The count
frequency is 4 times this frequency, because the
circuitry counts all four transitions.
—500 kHz
IM pulse width
Pulse width of the index input signal. Because the
index is active for a percentage of a revolution, the
speed will determine the pulse width.

Amount that the phase relationship between the AM
and BM inputs can deviate from the nominal 90°.
