„ General Status (Response)
Details on the general status area are shown below.
Mode: MOD_R
The MOD_R bit specifies the data block of bytes 1 to 7.
This bit will be the same as the mode given in the commands.
• 0: Response block for move commands
• 1: Response block for set/read commands
Ready: READY
The READY bit will be set to 1 when the DeviceNet Unit is ready to receive commands
from the host device. The READY status will be 0 when the power is turned ON, and when
the Unit Reset Command has been received and the DeviceNet Unit is initializing.
Main Power Supply Status: PWRON
The
PWRON
bit will be 1 when the main power supply of the W-series Servo Driver is
turned ON. If the main power supply is turned OFF, the bit will be 0 and the Servo ON and
other commands cannot be executed.
Emergency Stop: STOP_R
The STOP_R bit will be 1 when the Emergency Stop Command has been set to 0 and the
DeviceNet Unit is in emergency stop status. Set the Emergency Stop Command to 1 to clear
the emergency stop status, and this bit will change to 0. This status has negative logic.
Alarm: ALRM
The ALRM bit will be 1 when the DeviceNet Unit has detected an alarm. When all alarms
have been cleared by the Alarm Reset Command, this bit will change to 0.
Warning: WARN
The WARN bit will be 1 when the DeviceNet Unit has detected a warning. When all warn-
ings have been cleared by the Alarm Reset Command, this bit will change to 0.
When a warning has occurred, the commands other than data setting commands and the
command that generated the warning can still be executed normally.
