The FQM1 Modules have the following functions.

Basic interrupt functions
(FQM1-MMP21/MMA21)

Input Interrupts (4 points) (Input Interrupt Mode or Counter Mode)

Interval Timer Interrupt (1 point)

Setting range: 0.5 to 99,990 ms
Unit: 0.1 ms

Scheduled Interrupts

One-shot Interrupts

Constant Cycle Time Exceeded Error Clear Function

High-speed Counters
(FQM1-MMP21/MMA21)

High-speed Counter PVs (2 points)

Phase differential, Increment/decre-
ment, or Pulse + direction;
50 kHz or 500 kHz

No interrupts

Target Value Comparison Interrupts
(Count check interrupts)

Range Comparison and Bit Pattern Outputs

High-speed Counter Movement Measurement

Sampling time (1 to 9,999 ms) or cycle time

High-speed Counter Frequency Measurement

Measured frequency: 0 to 500 kHz (1 point)

High-speed Counter Latch (2 latch inputs)

(Latched high-speed counter PV can be read with PRV(881) instruction.)

Functions for Servo Drivers 
Compatible with Absolute 
Encoders
(FQM1-MMP21/MMA21)

Absolute Number of Rotations PV

Absolute PV

Absolute PV Preset Function

Absolute Offset Preset Function

Pulse Outputs
(FQM1-MMP21 only)

Pulse Outputs (2 points)

Pulse output without acceleration/deceleration, non-trapezoidal acceleration or decel-
eration, trapezoidal acceleration/deceleration, and electronic cam control

One-shot Pulse Output

Pulse ON time: 0.01 to 9,999 ms

Pulse Counter (for time measurement)

Measurement unit: Select 0.001 ms, 0.01 ms, 0.1 ms, or 1 ms.

Measurement range: 0000 0000 to FFFF FFFF hex

These three interrupt/bit pattern output 
settings can be set for the Pulse Out-
puts, One-shot Pulse Outputs, and 
Pulse Counter Functions listed above.

No interrupts

Target Value Comparison Interrupts
(Count check interrupts)

Range Comparison and Bit Pattern Outputs

Virtual Pulse Outputs
(FQM1-MMP21/MMA21)

The AXIS instruction generates trapezoidal acceleration/deceleration in a virtual axis.

Analog Outputs
(FQM1-MMA21 only)

Sloped Output by Instruction (2 points)

1 to 5 V, 0 to 5 V, 0 to 10 V, or 

−10 to 10 V

Immediate refreshing at instruction execution, analog output value hold function, offset/
gain adjustment supported

Analog Inputs
(FQM1-MMA21 only)

Immediate Refreshing by Instruction (1 point)

1 to 5 V, 0 to 5 V, 0 to 10 V, 

−10 to 10 V, or 4 to 20 mA

Offset/Gain Adjustment of Analog Input Value

High-speed Analog Sampling

The CTBL(882) instruction starts analog sampling when the high-speed counter 1 PV 
matches the preset target value.
