f677
f678 Pulse train output filter
Note 1: When item of f676 reaches "Reference of max. value", the number of pulse train set by f677
Note 2: The ON pulse width is maintained constant.
6 Note 3: The minimum pulse output rate is 10pps. Keep in mind that no pulses can be put out at any rate
Note 4: f676 = 12 is the motor drive frequency.
6.28.2 Calibration of analog output
f681 : Analog output signal selection
f684 : Analog output filter
f691 : Inclination characteristic of analog output
f692 : Analog output bias
 Function
* Optional frequency meter: When using QS60T, set f681 = 0 (meter option (0 to 1mA) output).
Title Function
Maximum numbers of
pulse train
Digital panel meter for reference
Type: K3MA-F (OMRON)
Connection terminal: OUT-E4, NO-E5
are sent to output terminals (OUT)
The ON pulse width is fixed at a width that causes the duty to reach 50% at the maximum pulse
number set with f677 .
Therefore, the duty is variable.
For example, the ON pulse width is
smaller than this.
Output signal from the FM terminal can be switched between 0 to 1mAdc output, 0 to 20mAdc output,
and 0 to 10Vdc output with the f681 setting. The standard setting is 0 to 1mAdc output.
Adjustment range
0.50-2.00 (kpps)
2-1000 (ms)
approximately 0.6 ms when f677 = 0.80 ,
approximately 0.5 ms when f677 = 1.00 ,
approximately 0.3 ms when f677 = 1.60 .
