9 Application Instructions API 150-199 a) When the reset signal flag M1346 = On, after zero return is completed, the PLC can send the reset signal to the servo drive and the signal will last for approximately 20ms. After 20ms, the reset signal will return to Off again. b) Output devices for reset signals of EH2/SV/EH3/SV2 series MPU:
CH0 (Y0, Y1) reset output device (Y10) CH1 (Y2, Y3) reset output device (Y11) CH2 (Y4, Y5) reset output device (Y12) CH3 (Y6, Y7) reset output device (Y13) Zero return speed Scan in circle Creep speed Program interrupt On DOG ON Off Reset signal Output near point signal (DOG) Reset signal Y4 or Y5 Inside 1 ms Greater than 20ms Off M1336, M1337 Pulse output monitor Note: The designated devices, X, Y, M, and S, other than the external input devices X10 ~ X17 will be affected by the scan period, 2 times of the scan period at worst. 2. The zero return operation:
a) When ZRN instruction is executed, the frequency of the first acceleration segment of CH0 (CH1) in EH2/SV/EH3/SV2 series MPU is set by D1340 (D1352). In SC series MPU, CH0 (CH1) will set creep speed as the start frequency. The acceleration time of EH2/SV/EH3/SV2/SC series MPU is set by D1343 (D1353). S1 will start to move when the acceleration reaches the zero return speed. b) When the DOG signal goes from Off to On, the zero return speed will decelerate to S 2 in the acceleration/deceleration time.
c) When the DOG signal goes from On to Off, the pulse output will immediately stop, 0 will be written in the present value registers (D1337, D1336) of CH0 pulses, (D1339, D1338) of CH1 pulses, (D1376, D1375) of CH2 pulses, and (D1378, D1377) of CH3 pulses in an EH2/SV/EH3/SV2 series MPU, and 0 will also be written in (D1349, D1348) of Y10 (CH0) pulses or (D1351, D1350) of Y11 (CH1) pulses in an SC series MPU. d) When the DOG signal goes from On to Off and the reset signal flag M1346 = On, Y4 (CH0) or Y5 (CH1) in EH series MPU will output a reset signal; Y10 (CH0), Y11 (CH1) , Y12 (CH2) and Y13 (CH3) in an EH2/SV/EH3/SV2 series MPU will output a reset signal.
e) For EH2/SV/EH3/SV2 series MPU, when the pulse output is completed and M1029, M1030, M1036 and M1037 are enabled, indication flag M1336 sent by CH0 pulses, M1337 by CH1, M1522 by CH2 and M1523 by CH3 will be Off. For SC series MPU, when the pulse output is completed, M1102 and M1103 will be DVP-PLC Application Manual 9-46 On
