E658077213Parameter name Title Setting value DetailsCom. Errorselectionf850 0 to 4 Sets the inverter operation at time of communication error.The action of inverter will be different depending on thestatus (during operation or halt) of the inverter. (Note 2)0: During halt Inverter stops after free run.During operation Inverter trips.1: During halt Inverter stops after free run.During operation Inverter stops after free run.2: Invalid (Setting is enabled with F10Moption connected.)3: During halt Inverter decelerates to stop.During operation Inverter decelerates to stop.4: During halt Inverter continues to run.During operation Inverter continues to run.Com. Errordetecting timef851 0 to 1000 Sets the time until the communication error is detected.Setting is done by a unit of ms. (Note 3)Reset function f899 0, 1 Resets the inverter station.0: No action1: To reset the inverter station. After resetting, settingdata returns to 0.(Note 1) For setting the parameters, never duplicate the station address on the same communication line.PLC rink relay register is automatically allocated according to the setting of the station address. As for thesetting of station addresses, consider the allocation of rink relay register that is determined by the otherstation addresses and the number of words that have been set in the parameters f831 to f836, andf841 to f846.The maximum setting value for station address is 255, however when 255 is set, only one word of scandata can be set. To set the scan data in its maximum value of 12 words, setting value of the stationaddress should be: 255-(12-1)= 244.(Note 2) Setting of “free-run stop” is valid when the “operation command mode selection” [cmod] isselected to the optional add-on cassette.Setting of “deceleration stop” is valid when the “operation command mode selection” [cmod] is selectedto the optional add-on cassette or when the “speed setting mode selection” [fmod] is selected to theoptional add-on cassette. At the same time the deceleration stop returns the command of run/stop and thespeed reference value to 0. Except when the above command setting is selected, inverter cannot bestopped.Furthermore when the “operation command mode selection” [cmod] is set to other than the optionaladd-on cassette and when the “speed setting mode selection” [fmod] is selected to the optional add-oncassette, in some cases inverter can not stop running because of the setting of the parameters (zero-speed operation setting). Torque control is valid when the “operation command mode selection” [cmod]is set to the optional add-on cassette, but the inverter operation becomes “free-run stop” at that time.
