Pulse Inputs and Analog
I/O Specifications FQM1-MMA21 (Analog I/O)
Item Specifications
Pulse
inputs Number of counters 2
Counter operations Linear counter, circular counter
Input signals Two words each for phase A, phase B, and phase Z.
Signal levels CH1: 24 V DC, line-driver
CH2: Line-driver
Input method Phase differential ×1
Phase differential ×2
Phase differential ×4
Increment/decrement
Pulse + direction
Counting speed Voltage 50 kHz
Line-driver 50 k Hz/500k Hz (phase
differential
× 4, 2 MHz)
Absolute Servo
Driver interfaces 2
SEN output specifications: 5 V PNP output, output
current 5 mA
When SEN signal is output to Servo Driver, Servo
Driver will transmit the number of encoder's rotations
to this Module. After that, it transmits pulse train cor-
responding to displacement of the number of rota-
tions to the Module.
