A main circuit voltage did not rise because of contactor welded.
Turns off the power supply once and turns on again.
Confirm that primary power supply voltage is in the specification value and wiring of the external emer -
gency stop line is correct.
When it comes back, contact to the dealer.
The servo cannot be turned ON while the enable switch is OFF.
Turn the enable switch ON before turning the servo ON.
The brakes cannot be released while the emergency stop is input.
Release the emergency stop state before operating.
The brakes cannot be operated during servo ON.
Turn the servo OFF before operating.
The brakes cannot be released during the brake release process.
Operate it after brake is released.
The brakes cannot be locked during the brake lock process.
Operate it after brake is locked.
Other parameters cannot be changed during the parameter change process.
Carry out the parameter change process again.
Changes of the servo parameter failed.
Carry out the parameter change process again.
The origin setting data is not correct.
Set the correct origin setting data.
Confirm mistakes such as "1(one)" and "I(alphabet)", or "O(alphabet)" and "0(zero)", etc.
The origin data is illegal in robot arm
Setting the origin
The origin is not set.
Re-execute after setting the origin.
The origin was not set simultaneously for the interference axis.
Set the origin simultaneously for the interference axis. For example, the J3 axis and the J4 axis of the RH
type robot. Please refer to the section of origin setting of separate manual: "Robot Arm Setup and Mainte -
nance" for details.
The origin was set during servo ON.
Turn the servo OFF before setting the origin.
The parameter (MEAJAR) setting is illegal.
Or the setting value of the parameter related to addition axis control have exceeded the controllable oper -
ating range.
The useful range of the operating range setting parameter (MEAJAR) is -131072.00 to +131072.00. Correct,
if the set value is over the range.
Or confirm the setting value of the parameter related to addition axis control.
