G5 Series AC Servo Drives With Built-in EtherCAT Communications, Linear Motor Type
Cause
The value that is obtained by dividing the
absolute encoder position (in pulses) by the
electronic gear ratio exceeded 2
(2,147,483,648) during the initialization of
*5
position data.
The position error in pulses exceeded
2 29
(536,870,912). Alternatively, the
position error in command units exceeded
2 30
(1,073,741,824).
At least one of the input photocouplers for
safety inputs 1 and 2 turned OFF.
There is a duplicate setting in the input
signal (IN1, IN2, IN3, and IN4) function
allocations.
There is a duplicate setting in the input
signal (IN5, IN6, IN7, and IN8) function
allocations.
There is an undefined number specification
in the input signal (IN1, IN2, IN3, and IN4)
function allocations. Alternatively, a logic
setting error was detected.
There is an undefined number specification
in the input signal (IN5, IN6, IN7, and IN8)
function allocations. Alternatively, a logic
setting error was detected.
There is an undefined number specification
in the output signal (OUTM1) function
allocation.
There is an undefined number specification
in the output signal (OUTM2) function
allocation.
There is an error in the latch input function
allocation.
• The function was allocated to input signals
other than IN5, IN6, or IN7.
• The function was allocated to NC.
• The function was not allocated for all
control modes.
12 Troubleshooting and Maintenance
Review the operation range of the absolute
encoder position and the electronic gear
31 ratio.
• Check to see if the Linear Motor operates
according to the position command.
• Check on the force monitor to see if the
output force is not saturated.
• Adjust the gain.
• Maximize the Force Limit setting being
used.
• Wire the external encoder as shown in the
wiring diagram.
Check the input wiring of safety inputs 1
and 2.
Allocate the functions to the connector pins
correctly.
