(PK2V)
NOTE
This function is disabled when the velocity loop
high cycle management function (Subsec. 4.4.1) is
used with Series 9096.
[Tip] Example of setting an arbitrary magnification in the stop state
(a) When the cutting feed/rapid traverse switchable velocity loop
gain function (Sec. 4.3) is used, and
Bit 3 of No. 1958 (Series 15i) or bit 3 of No. 2016 (Series 30i,
16i, and so on) = 1
• If the mode in the stop state is the cutting mode:
Actual velocity gain in the stop state = (velocity gain setting
for cutting) × 0.75
• If the mode in the stop state is the rapid traverse mode:
Actual velocity gain in the stop state = (velocity gain setting
for rapid traverse) × 0.75
(b) When the cutting feed/rapid traverse switchable velocity loop
gain function (Sec. 4.3) is used,
Bit 3 of No. 1958 (Series 15i) or bit 3 of No. 2016 (Series 30i,
16i, and so on) = 1, and
Bit 3 of No. 1747 (Series 15i) or bit 3 of No. 2207 (Series 30i,
16i, and so on) = 1
• If the mode in the stop state is the cutting mode:
Actual velocity gain in the stop state = (velocity gain setting
for cutting) × 0.5
• If the mode in the stop state is the rapid traverse mode:
Actual velocity gain in the stop state = (velocity gain setting
for rapid traverse) × 0.5
(c) When the cutting feed/rapid traverse switchable velocity loop
gain function (Sec. 4.3) is used,
Bit 3 of No. 1958 (Series 15i) or bit 3 of No. 2016 (Series 30i,
16i, and so on) = 1, and
No. 2373 (Series 15i) or No. 2324 (Series 30i,16i, and so on) = α
• If the mode in the stop state is the cutting mode:
Actual velocity gain in the stop state = (velocity gain setting
for cutting) × α/100
• If the mode in the stop state is the rapid traverse mode:
Actual velocity gain in the stop state = (velocity gain setting
for rapid traverse) × 0.75
