User Manual of EM760 High-Performance Inverter The PLC stop memory is to record the current simple PLC running times (F18.10), running stage (F18.11), and running time at the current stage (F18.12). The inverter will continue to run from the memory stage during next operation. If you choose no memory, the PLC process will be performed everytime the inverter is started. The PLC power-down memory is to record the current simple PLC running times (F18.10), running stage (F18.11), and running time at the current stage (F18.12) before the memory is powered off. The inverter will continue to run from the memory stage when the inverter is powered on again.
If you choose no memory, the PLC process will be performed everytime the inverter is powered on. In order to meet different working conditions, the running time involved in the PLC function is set to a numerical value. Its specific meaning needs to be set in conjunction with the simple PLC time unit (F08.18). At present, there are two types ofunit: second and minute. 99 Function code Function codename Parameter description Unit Default setting Attribute F08.17 Simple PLC memory options Ones place: Stop memory options 0: no memory (from the first segment) 1: memory (from the moment of stop) Tens place: Power-down memory options 0: no memory (from the first segment) 1:
