Bit 15: Drive_Is_Enabled –
Set to “1” when the motor driver section of the Networked Driver is enabled
and current is available to the motor. Set to “0” when the motor driver section is disabled. If this bit
is set to “1”, the motor current remains present when an E-Stop input is active. This bit will remain
set if the motor current has been removed because motion is not occurring and the Idle Current
Reduction is programmed to its 0% setting. Motor current is removed if there is a Driver_Fault (Bit
7 below) regardless of the state of this bit.
Bit 14: Stall_Detected –
Set to “1” when a motor stall has been detected.
Bit 13: OUT1_State –
Present actual state of Output 1. When this bit is set to “1”, the output is in its on state
and conducts current.
Bit 12: Reserved Bit –
Will always equal zero.
Bit 11: Heartbeat_Bit –
This bit will change state approximately every 500 milliseconds. Monitor this bit to
verify that the unit and network connection are operating correctly.
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.
Set while in Electronic Gearing mode if the Numerator or Denominator are set outside their range of
1 to 255.
Bit 8: Reserved –
Will always equal zero.
Bit 7: Driver_Fault –
If the driver section of the Networked Driver is enabled, this bit will be a “1” during
a Over temperature Fault, a Short Circuit Fault, or when the Interlock Jumper is missing. This fault
can be cleared by issuing a
programming block with the Clear_Driver_Fault bit,
(CMD_word1, bit 10) set to “1”. For additional information, see
Notes on Clearing a Driver Fault
on page 83. Note that the driver fault bit is set at power up if the interlock is missing and the driver is
immediately enabled.
Bit 6: Reserved –
Will always equal zero.
Bit 5: SafeOp –
Set to “1” when the network is in Safe_Op mode. Moves cannot be commanded while in
this mode. Reset to “0” when the network is in Operational mode. Moves can be commanded when
in Op mode.
Bit 4:
Temperature_Above_90C –
This bit is set to “1” when the processor internal temperature exceeds
90°C. At this point, the heatsink temperature is typically above 80°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 through the device.
Bit 3: Reserved –
Will always equal zero.
