9 Application Instructions API 150-199 API 156 Operands: S 1 : Zero return speed S 2 : Creep speed S 3 : Near p oint signal (DOG) D : Pulse output device (please use transistor output module) Explanations: 1. When S 1 and S 2 are used in device F, only 16-bit instruction is applicable. 2. S 1 and S 2 of SC series MPU only support device K, H and D. S 3 of SC series MPU only supports device X10 and X11. 3. Flag: see remarks of API 155 ABSR and API 158 DDRVI for more details. 4. S 1 is the starting speed of zero return operation.
For EH2/SV/EH3/SV2 series MPU, the 16-bit instruction can designate the range of the speed, which is 10 ~ 32,767Hz and the range designated by the 32-bit instruction is 10 ~ 200,000Hz. If the designated speed is slower than 10Hz, the zero return will operate at 10Hz and when the designated speed is faster than 200kHz, the zero return will operate at 200kHz. For SC series MPU, the 32-bit instruction can designate the range of speed , which is 100 ~ 100,000Hz. If the designated speed is slower than 100Hz, the zero return will operate at 100Hz, and when the designated speed is faster than 100kHz, the zero return will operate at 100kHz. 5.
S 2 is the designated low speed after the near point signal (DOG) is On. EH2/SV/EH3/SV2 series MPU can designate the range of S 2 , which is 10 ~ 32,767Hz and SC series MPU can designate the range 100 ~ 100,000Hz. 6. S 3 is the designated near point signal (DOG) input (input from A contact). In EH2/SV/EH3/SV2 series MPU, if devices other than the external output device (X10 ~ X17), e.g. X, Y, M, S are designated, they will be affected by the scan period, resulting in dispersion of the zero point. In addition, please note that the MPU cannot designate the same input points X10 ~ X17 as those designated by DCNT and PWD instructions.
SC series MPU can only designate X10 and X11 and cannot designate the same input points as those designated by DCNT instruction. 7. EH series MPU has two groups of A/B phase pulse output, CH0 (Y0, Y1) and CH1 (Y2, Y3); EH2/SV/EH3/SV2 series MPU has four groups of A/B phase pulse output, CH0 (Y0, Y1), CH1 (Y2, Y3), CH2 (Y4, Y5) and CH3 (Y6, Y7). See remarks for the setup methods. 8.
