AM, BM, and IM Input Specifications for TTL Encoders
AM, BM, and IM Input Specifications for Sine/Cosine Encoders
Feedback Power Supply
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
Current draw, dc 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, since the circuitry
counts all four transitions.
— 5.0 MHz
IM pulse width
Pulse width of the index input signal. Since the index is
active for a percentage of a revolution, the speed will
determine the pulse width.
