Operands:
S 1 : Target frequency of output S 2 : Target number of pulses S 3 : Gap time and gap
frequency D: Pulse output device (Y0, Y2)
Explanations:
1. Max frequency for S 1 : 100kHz. Target frequency can be modified during the execution of
instruction. When S 1 is modified, VSPO will ramp up/down to the target frequency according
to the ramp-up gap time and gap frequency set in S 3.
2. S 2 target number of pulses is valid only when the instruction is executed first time. S 2 can
NOT be modified during the execution of instruction. S 2 can be a negative value, however, if
the output direction is not specified in D1220/D1221, PLC will take this value as a positive
value. When target number of pulses are specified with 0, PLC will perform continuous
output.
3. S 3 occupies 2 consecutive 16-bit devices. S 3 +0 stores the gap frequency S 3 +1 stores the gap
time. Parameter setting can be modified during the execution of instruction. Set range for
S 3 +0: 1Hz ~ 32767Hz; set range for S 3 +0: 1ms ~ 80ms. If set value exceeds the available
range, PLC will take the upper or lower bound value.
4. D pulse output device supports only Y0 and Y2. If Y1 and Y3 is required for output direction
control, D1220 or D1221 has tobe set as K1(Pulse/Dir).
5. Parameters set in S 3 can only be modified while modifying the value in S 1. When target
frequency is set as 0, PLC will ramp down to stop according to parameters set in S 3 . When
the output is stopped, PLC will enable the flags indicating pause status (Y0: M1538, Y2:
M1540). If target frequency other than 0 is specified again, pulse output will ramp up to target
frequency and operates untill target number of pulses are completed.
