Description: (ELC-PH/PV)
1.
S
1
is specified as the zero point return speed. For the ELC-PV series, the range of the 16-bit
value is from 10 ~ 32,767Hz and the range of the 32-bit value is from 10 ~ 200,000Hz. For the
ELC-PH series, the range of the 32-bit value is from 100 to 100,000Hz. When the speed is
greater (less) than the maximum (minimum) range, the maximum (minimum) range value will
be used.
2.
S
2
is specified as the creep speed (start and end frequency), the lower speed after the near
point signal (DOG) turns ON. For the ELC-PV series, the range is from 10 ~ 32,767Hz. For the
ELC-PH series, the range is from 100 to 100,000Hz.
3.
S
3
is specified as the near point signal (DOG) input. In the ELC-PV series, if devices other than
the input device (X10 ~ X17), e.g. X, Y, M, S are used, they will be affected by the scan time,
resulting in dispersion of the zero point. In addition, please note that the same input points X10
~ X17 used for this instruction should not be used by the DCNT and PWD instructions. The
ELC-PH series can only use X10 and X11.
4.
The ELC-PV series has four groups of A/B phase pulse outputs, CH0 (Y0, Y1), CH1 (Y2, Y3),
CH2 (Y4, Y5) and CH3 (Y6, Y7).
5.
ELC-PH Pulse output device
D
only can be specified as Y10, Y11.
6.
D1343 (D1353) is the accel/decel time setting of Y10 (Y11) and its available range is 50 to
20000ms. If this value exceeds 20,000 ms, it uses 20,000ms. If the setting is less than 50 ms,
it will use 50 ms.
7.
When executing the API 158 DRVI and API 159 DRVA instructions, the ELC stores the current
pulse count in D-registers so that the machine position is always known. For the ELC-PV
series, Y0: D1337, D1336; Y2: D1339, D1338, Y4: D1376, D1375; Y6: D1378, D1377. For the
ELC-PH series, Y10: D1348, D1349; Y11: D1350, D1351. This allows the user to keep track of
