4. The result of the second execution:
a) The actual output number 50,560 – estimated output number 50,500 = 60
b) 60 x (1/200Hz) = 300ms (idling time)
c) 300ms is an appropriate value. Therefore, set the percentage value (D1198) to K101.
Description: (ELCM-PH/PA)
1. The corresponding interrupt pointers of
S
1
:
Source device X4 X6 C243 ~ C254
Associted outout Y0 Y2 Y0 Y2
No. of Interrupt pointer
I40 I60
I010 I030
= 1: rising-edige triggered; = 0: falling-edge triggered
a) When
S
1
designates input points X and the pulse output reaches the target number of
feedbacks in
S
2
, the output will continue to operate with the last frequency until interrupts
occur on input points X.
b) When
S
1
designates high speed counters and the pulse output reaches the target number
of feedbacks in
S
2
, the output will continue to operate with the last frequency until the
feedback pulses reache the target number.
c)
S
1
can be a high speed counter C or an input point X using an external interrupt. If
S
1
is C,
the DCNT instruction should be executed before enabling the high-speed counting
function. If input interrupts are used, the EI instruction with I0x0 should be enabled for
external interrupts.
2. The range of
S
2
is -2,147,483,648 ~ +2,147,483,647 (+ / - indicates the positive / negative
rotation direction). the present value of the pulse output in CH0 (Y0, Y1) and CH1 (Y2, Y3)
increases in the positive direction and decreases in the negative direction. Registers storing
the present value of the pulse output are CH0(D1031 High, 1030 Low), CH1(D1337 High,
D1336 Low)
3. If
S
3
is less than 6Hz, the output will operate at 6Hz; if
S
3
is greater than 100kHz, the output
will operate at 100kHz.
4.
D
can only designate Y0 (Direction signal output: Y1) or Y2 (Direction signal output: Y3). The
direction signal output will be OFF only when the instruction is not being executed, i.e. the
completion of the pulse output will not reset Y1 or Y3.
5. D1340 and D1352 store the start/end frequencies of CH0 and CH1. Min. 6Hz, default: 100Hz.
6. D1343 and D1353 store the ramp up/down time of CH0 and CH1. If the ramp up/down time is
shorter than 20ms, ELC will operate in 20ms. Dafault: 100ms.
7. Ramp-down time of CH0 and CH1 can be specified by the setting (M1534, D1348) and (M1535,
D1349). When M1534 / M1535 is ON, ramp-down time of CH0 and CH1 is set with D1348 and
D1349.
