Cause
The position deviation value based on the encoder
29
pulse has exceeded 2
(536870912).
Duplicate assignment of a function to the input signals (SI1,
SI2, SI3, SI4, and SI5).
Duplicate assignment of a function to the input signals (SI6,
SI7, SI8, SI9, and SI10).
Undefined numbers are used for the function assignment of
the input signals (SI1, SI2, SI3, SI4, and SI5).
Undefined numbers are used for the function assignment of
the input signals (SI6, SI7, SI8, SI9, and SI10).
Undefined numbers are used for the function assignment of
the output signals (SO1, SO2, and SO3).
The deviation counter clear function is assigned to an input
signal other than SI7.
The command pulse inhibition input enable function is
assigned to an input signal other than SI10.
The motor has exceeded the allowable motor operation
range specified in Pr5.14 "Motor working range setup"
against the position command input range.
1) The gain is not appropriate.
2) The set value specified in Pr5.14 is too small.
When the EEPROM was read out when the power was
turned on, the data in the parameter storage area was
destroyed.
When the EEPROM was read out when the power was
turned on, the data that has been confirmed for writing was
destroyed.
When Pr5.04 "Over-travel inhibit input setup" is set to 0,
both of the positive/negative-direction drive prohibition
inputs (POT /NOT) were turned on.
When Pr5.04 is set to 2, either of the
positive/negative-direction drive prohibition inputs was
turned on.
・ Check if the motor runs according to the position
command.
・ Check the torque monitor to see if the output torque
has saturated.
・ Perform a gain tuning.
・ Set the upper limit in Pr0.13 "1
nd
Pr5.24 "2
torque limit".
・ Make the encoder wiring connections to the wiring
diagram.
・ Correct the function assignment to the connector pins.
・ Correct the function assignment to the connector pins.
・ Correct the function assignment to the connector pins.
・ Correct the function assignment to the connector pins.
・ Correct the function assignment to the connector pins.
・ Correct the function assignment to the connector pins.
・ Correct the function assignment to the connector pins.
① Verify the gain (the balance between the position loop gain
and velocity loop gain) and the inertial ratio.
② Set a greater value in Pr5.14. Or, set Pr5.14 to 0 to disable
the protection function.
・ Redo the entire parameter setting.
・ If the problem persists, there may be a failure. Replace the
servo drive with a new one and return the old one to the
dealer of the product for investigation (repair).
There may be a failure. Change the servo drive. Return
them to the dealer for investigation (and repair).
・ Check for malfunctions of switches, wires and power
supplies connected to the positive/negative overtravel limits.
Pay special attention to the power supply (DC 12 - 24 V) to
see if it is taking too much time to start.
