PARAMETERS
(4) Operation at error occurrence
*1 Can be selected using Pr. 75 Reset selection/disconnected PU detection/PU stop selection
*2 Can be selected using Pr. 122 PU communication check time interval, Pr. 336 RS-485 communication check time interval, Pr. 502 Stop mode selection at
communication error or Pr. 539 Modbus-RTU communication check time interval.
*3 As controlled by the communication option.
*4 In the PU jog operation mode, operation is always stopped when the PU is disconnected. Whether fault (E.PUE) occurrence is allowed or not is as
set in Pr. 75 Reset selection/disconnected PU detection/PU stop selection.
*5 When Pr. 550 NET mode operation command source selection = 1 (RS-485 terminals valid) or Pr. 550 NET mode operation command source selection =
9999 and the communication option is not fitted
*6 When Pr. 550 NET mode operation command source selection = 0 (communication option valid) or Pr. 550 NET mode operation command source selection
= 9999 and the communication option is fitted
