CONFIGURATION SETTINGS CHAPTER 4: FUNCTIONALITY

prior to power loss and not be in run when power is lost, therefore no run state to restart. With the DeviceNet fault enabled, the power recovery would reset the DeviceNet connections and the DeviceNet would act as if it's not communicating thus a DeviceNet fault.

Potential safety hazards must be considered and the appropriate setup chosen for each individual application.

•DevNet Fault (DeviceNet fault): If enabled, the LM10 will consider DeviceNet network failures as a fault, tripping relay(s) and recording into the history record. Default condition is enabled.

•50Hz Sys (50 Hz system): The default setting is for a 60 Hz system; use this menu item to select a 50 Hz system instead. This does effect the sampling buffer and internal calculations. Setting this improperly will result in some inaccuracies.

•Poll Data (poll data group): This setting selects the pre-defined group of parameters in the DeviceNet input poll data. Refer to Poll Data on page 5–45for details. LM10 revisions 1.40 and lower do not support this setting.

For this setting, group 1 is 7 bytes, group 2 is 12 bytes, group 3 is 22 bytes, group 4 is 7 bytes.

Poll group 4 option (7 bytes) is available only for firmware rev 1.70 and higher.

If PDU v1.70 or higher is used for LM10 firmware v1.6x and lower, Poll Data group 4 (which is unavailable in firmware v1.6x and lower) will be displayed in the PDU but cannot be set to the MPR unit.

•Reset Run Hrs (reset motor running hourse timer): The user may desire to reset the motor running hours after replacement or maintenance. Note that hours are stored in full-hour increments up to 65535. Typical bearing life is less than 50000 hours. Please note that shutting down the unit will lose any partial hour accrued.
