P21.27
Pulse
superposition
speed
reference (P00.06=12) or pulse position mode
(P21.00=1):
1. Input terminal function #68 (enable pulse
superposition)
When the rising edge of the terminal is detected,
the pulse setting is increased to the value of
P21.26, and the pulse reference channel is
compensated by the pulse superposition rate set
in P21.27.
2. Input terminal function #67 (progressive
increase of pulses)
When this terminal is enabled, the pulse
reference channel is compensated by the pulse
superposition rate set in P21.27.
Note:
Terminal filtering set in P05.09 may
slightly affect the actual superposition.
Example:
P21.27 = 1.0/ms; P05.05 = 67
If the input signal of terminal S5 is 0.5s, the
actual number of superposed pulses is 500.
3. Input terminal function #69 (progressive
decrease of pulses)
The sequence of this function is the same as
those described above. The difference lies in
that this terminal indicates that negative pulses
are superposed.
Note:
All the pulses described here are
superposed on the pulse reference channel (A2,
B2). Pulse filtering, electronic gear, and other
functions are valid for superposed pulses.
4. Output terminal function #28 (pulse
superposing)
When pulses are superposed, the output
terminal operates. After pulses are superposed,
the terminal does not operate.
