Description
positioning in spindle orientation.
Setting range: 0.000–60.000s
P21.26: -9999–32767
P21.27: 0–3000.0/ms
The function is valid in the pulse speed
reference (P00.06=12) or pulse position mode
(P21.00=1).
1. Input terminal function 68 (Enable the pulse
superimposition)
When the rising edge of the terminal is detected,
add the value set in
value, and compensate to the pulse reference
channel based on the pulse superposition speed
set in P21.27.
2. Input terminal function 67 (pulse increase)
When the terminal is valid, superpose the pulse
value to the pulse reference channel based on
the pulse superposition speed set in P21.27.
Note: Terminal filter
actual superposed value.
For example:
P21.27=1.0/ms
P05.05=67
When the S5 ternimal input signal is 0.5 s, the
actual superposed pulses = 500 pulses.
3. Input terminal function 69 (pulse decrease)
The time sequence of this function is same as
the above. The difference is that this terminal is
the pulse number that is superposed
degressively.
Note: The pulses mentioned above are
superposed to A2 and B2 of pulse reference
channel. Functions such as filtering and
electronic gear are still valid for superposed
pulses.
4. Output terminal function 28 (during pulse
superposition)
During the pulse superposition, the output
-306-
P21.26 to the set pulse
P05.09 may affect the
