Operands:

: Target frequency to be changed S

: Gap time and gap frequency D: Pulse output

device (Y0, Y2)

Explanations:

1. Max frequency for S

: 100kHz. When ICF instruction executes, frequecy changing will start

immediately with ramp-up/down process.

2. ICF instruction has to be executed after the execution of DVSPO or DPLSY instructions.

When the instruction is used together with DVSPO, operands S

, S

, D of DICF has to be

assigned the same device with S

, S

, D of DVSPO. When the instruction is used with DPLSY,

operands S

and D has to be assigned the same device with S

and D of DPLSY.

3. If ICF instruction is used with DPLSY instruction, operand S

is invalid.

4. When ICF instruction is used with DVSPO instruction, parameter setting of S

functions the

same as S

DVSPO instruction, specifying the gap time and gap frequency of

ramp-up/down process.

5. D pulse output device supports only Y0 and Y2.

6. The instruction is suggested to be applied in interrupt subroutines for obtaining the better

response time and eexecution results

7. For associated flags and registers, please refer to Points to note of API 198 DVSPO

instruction.

Function Explanations:

1. If users change the target frequency by using DVSPO instruction, the actual changing timing

will be delayed due to the program scan time and the gap time as below.
