Abbreviation Display Alarm cause<br />
RGOL The PB amplifier regulates the regeneration voltage by software<br />
control and detects regeneration error when the stipulated value is<br />
exceeded.<br />
Regeneration to the power source is prevented within the amplifier.<br />
Contact <strong>Sanyo</strong> <strong>Denki</strong> for assistance if regeneration control is not<br />
sufficient.<br />
When excessive regeneration voltage occurs, the hardware<br />
might be damaged. When used with abrupt deceleration or<br />
under excessive load, gradually accelerate and decelerate<br />
starting from low-velocity operation to check the drive.<br />
Confirm the rated load limit for each motor before operation.<br />
Refer to Chapter 6 for more information about load limit.<br />
ORG Indicates a zero-return error.<br />
For C-phase detection zero-return<br />
Indicates that the C-phase could not be detected within one rotation of<br />
the motor shaft<br />
For SDN detection, Push zero-return<br />
Indicates that the drive was incomplete within the travel distance range<br />
set by command 23h.<br />
Wrap Around Indicates the overflow of absolute position counter.<br />
Command 14h-DAT4-Bit1 can be used to enable or disable detection<br />
of this condition. Not detected on the initial value.<br />
LAE Indicates a count error of the encoder counter.<br />
Detected only during the motor operation.<br />
Confirm that there is no sensor error caused by shock to the motor or<br />
excessive noise.<br />
OC Indicates excess current in the motor.<br />
It does not function as protection for short circuit or earth-fault on the<br />
power line.<br />
Contact <strong>Sanyo</strong> <strong>Denki</strong> for assistance if problem occurs.<br />
EEPER Indicates a non-volatile memory data error.<br />
After detecting the memory error, the parameters are reset to the<br />
initial factory settings.<br />
