Input Data Format (continued)
Status Word 1 Format (continued)
Bit 10: Limit_Condition –
This bit is set if an End Limit Switch is reached during a move. This bit will be
reset when the Limit Switch changes from its active to inactive state, or when a Reset Errors Com-
mand is issued.
Bit 9: Invalid_Jog_Change –
Set during a Jog Move if parameters are changed to invalid values. Parame-
ters that can be changed during a Jog Move are Programmed Speed, Acceleration, and Deceleration.
Bit 8: Reserved –
Will always equal zero.
Bit 7: Driver_Fault –
If the driver section of the SMD23E2 or SMD24E2 is enabled, this bit will be a “1”
during a Overtemperature Fault. Even though the driver is enabled, it will not supply current to the
motor until the motor’s temperature decreases to a safe value. At this point the fault will clear itself.
Bit 6: Connection_Was_Lost –
If the
physical
network connection is lost at any time, this bit will be set
when the connection is re-established. The
Input_Error
bit will also be set. Note that this bit is not
set if the communication loss is on the protocol level, not the physical level.
Bit 5: Reserved –
Will always equal zero.
Bit 4:
Temperature_Above_90°C –
This bit is set to “1” when the processor internal temperature exceeds
90°C. At this point, the heatsink temperature is typically near 83°C. If this bit trips often and you
want to lower the operating temperature of the unit, consider changing how the device is mounted, or
installing a fan to force additional airflow over the device.
Bit 3: Reserved –
Will always equal zero.
Bit 2: Reserved –
Will always equal zero.
Bit 1: IN2_Active –
“1” when Input 2 is in its active state. The active state of the input is programmed as
section starting on page 63.
Bit 0: IN1_Active –
“1” when Input 1 is in its active state. The active state of the input is programmed as
section starting on page 63.
Notes on Clearing a Driver Fault
A Driver Fault occurs when there is an over temperature condition. When a Driver Fault occurs, the
SMD23E2 or SMD24E2 will set bit 7 of the Status Word 1 word in the Network Input Data. Even though the
driver is enabled, it will not supply current to the motor until the motor’s temperature decreases to a safe
value. At this point the fault will clear itself.
