If Pr x.09 is changed form 0 to 1, prior to the drive being re-initialised then the re-initialisation will cause all I and O registers (Pr x.10 to Pr x.29) to be
cleared, assuming that all configuration parameters are valid. Any other drive re-initialisation or cycling of the drive's power will leave the registers
unaffected.
Defines parameters that are input to the PLC.
If Pr x.09 = 0 then Pr x.10 to Pr x.19 will be used for configuring the input cyclic data mappings.
Pr x.10 to Pr x.19 will only be read following a reset. Any invalid entry will result in a trip 61 (Invalid configuration parameter(s)). Cyclic communication
will not commence unless all configuration parameter(s) are found to be correct, following a reset. Pr x.06 will remain at -2 therefore indicating an
unsuccessful initialisation.
Defines parameters that are output from the PLC.
If Pr x.09 = 0 then Pr x.20 to Pr x.29 will be used for configuring the output cyclic data mappings.
Pr x.20 to Pr x.29 will only be read following a reset. Any invalid entry will result in the status being set to -3 and mapping error information being
placed in Pr x.49.
Cyclic communication will not commence unless all configuration parameter(s) are found to be correct, following a reset. Pr x.06
will remain at -3 therefore indicating an unsuccessful initialisation.
If after a drive mode change the mappings parameters become invalid, the drive will trip ‘invalid configuration parameters’.
Effect of register control on mapping parameters
If Pr x.09 = 1 then the input cyclic data will be mapped directly from Pr x.10 to Pr x.19 and the output cyclic data will be mapped directly into Pr x.20
to Pr x.29. For this reason if a length of more than 10 is selected for either the input or output cyclic data only the first 10 words can be used. A cyclic
data mode of greater length than 10 will result in an over-length error.
