Error name
Operation status at error occurrence
■Description
■Operation status at error occurrence
■Description
Hardware is faulty.
■Operation status at error occurrence
The system stops.
■Description
A PLC READY signal (Y0) is turned OFF during
operation.
■Operation status at error occurrence
The system stops with the setting (deceleration
stop/sudden stop) of the detailed parameter 2
Sudden stop selection (stop group 2). (Note that the
deceleration stop only occurs during the manual
pulse generator operation.)
■Description
The drive unit READY signal is turned OFF during
operation.
■Operation status at error occurrence
The system stops immediately.
■Description
The start of an operation is requested when the
drive unit READY signal is OFF.
■Operation status at error occurrence
The system does not start.
■Description
The personal computer cannot communicate with
the CPU module.
■Operation status at error occurrence
The system stops with the setting (deceleration
stop/sudden stop) of the detailed parameter 2
Sudden stop selection (stop group 2). (Note that the
deceleration stop only occurs during the manual
pulse generator operation.)
Action/Related buffer memory address/Set
range (Setting with program)
■Action
■Action
Check that there is no influence from noise.
■Action
Review the program which turns ON/OFF PLC
READY signal (Y0).
■Action
Check the power supply status of the drive unit,
wiring to the drive unit, and the connection status
of the connector.
■Action
• Check the power supply status of the drive unit,
wiring to the drive unit, and the connection
status of the connector.
• Check the values in [Pr.22] Input signal logic
selection.
• When a drive unit without READY signal output
is used, wire the system so that the drive unit
READY signal input of the LD75 is always ON.
■Action
• Check that there is no error on the personal
computer side I/F to which a cable is
connected.
• Because communication takes a long time
between the personal computer and a CPU
module, ensure high-speed communication by
setting the transmission speed to high at the
transfer setup of GX Configurator-QP or GX
Works2, or connecting the personal computer
directly to the communication I/F of the CPU
module.
• Reduce the load of communication by stopping
the access to a CPU module from GX
Developer or GX Works2 (such as monitor
function).
