OMNUC G5-SERIES AC SERVOMOTOR AND SERVO DRIVE USER'S MANUAL
Cause
The position error for the encoder
feedback pulse reference exceeded
29
±2
(536,870,912).
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, IN4, and
IN5) function allocations.
There is a duplicate setting in the
input signal (IN6, IN7, IN8, IN9, and
IN10) function allocations.
There is an undefined number
specification in the input signal (IN1,
IN2, IN3, IN4, and IN5) function
allocations.
There is an undefined number
specification in the input signal (IN6,
IN7, IN8, IN9, and IN10) function
allocations.
There is an undefined number
specification in the output signal (SO1
and SO2) function allocations.
There is an undefined number
specification in the output signal
(SO4) function allocation.
The error counter reset input
(ECRST) was allocated to something
other than input signal SI7.
The pulse prohibition input (IPG) was
allocated to something other than
input signal SI10.
The Servomotor exceeded the
allowable operating range set in the
Overrun Limit Setting (Pn514) with
respect to the position command
input range.
· The gain is not suitable.
· The set value of Pn514 is too
small.
11-4 Troubleshooting
Measures
· Check that the motor rotates
according to the position
command.
· Check on the torque monitor that
the output torque is not saturated.
· Adjust the gain.
· Set the No. 1 Torque Limit
(Pn013) or No. 2 Torque Limit
(Pn522) is set to the maximum
value.
· Connect the encoder cable
correctly.
Check the input wiring of safety inputs
1 and 2.
Allocate the functions to the
connector pins correctly.
Check the gain (the balance between
position loop gain and speed loop
gain) and the inertia ratio.
· Increase the set value of Pn514.
Alternatively, set Pn514 to 0 to
disable the protection function.
