Chapter 1Outlines of the HA-655 driver<br />
Abnormal encoder signal (51)<br />
The alarm occurs when the driver has failed to receive two sequential signals. To clear the alarm after<br />
troubleshooting, shut off the control power once and turn it on again.<br />
UVW failure (52)<br />
The alarm occurs when the encoder UVW signals are abnormal. To clear the alarm after troubleshooting,<br />
shut off the control power once and turn it on again.<br />
ABS system failure (53)<br />
For the absolute encoder, the alarm occurs when all power supplies (power supply, built-in condenser,<br />
and battery) for the encoder are failure. For example, it occurs at the first power supply after purchasing,<br />
and at power supply after disconnecting the cable between the driver and the encoder for a long duration.<br />
To recover the alarm, input the multi-turn data clear signal at least 4 seconds, and shut off the control<br />
power once and turn it on again.<br />
ABS MTD overflow (54)<br />
For the absolute encoder, the alarm occurs when the count for multi-turn data (MTD) goes beyond the<br />
range of +4095 to - 4096 turns (motor axis). To recover the alarm, input the multi-turn data clear signal at<br />
least 4 seconds, and shut off the control power once and turn it on again.<br />
ABS multi-turn data error (55)<br />
For the absolute encoder, during an energy-saving <strong>mode</strong>, where no power by power supply but the<br />
encoder circuit is active only by the power of a built-in condenser and a built-in battery, the alarm occurs<br />
when the encoder rotates too fast at the acceleration rate and <strong>speed</strong> exceeding the recording ability of<br />
the multi-turn counter on the <strong>mode</strong>. To recover the alarm, input the multi-turn data clear signal at least 4<br />
seconds, and shut off the control power once and turn it on again.<br />
ABS low battery voltage (56)<br />
For the absolute encoder, when voltage of the built-in battery is low. To recover the alarm, change the<br />
battery for a new one, and shut off the control power once and turn it on again.<br />
ABS send data rule error (57)<br />
The absolute encoder rotates more than 127 resolvable pulses by external torque during transmitting<br />
absolute data. To recover the alarm, shut off the control power once and turn it on again.<br />
Error counter overflow (60)<br />
The alarm occurs when an error count exceeds the set value in [parameter <strong>mode</strong>][6: <strong>position</strong> error<br />
allowance]. It is possible to clear the alarm by inputting a signal to [CN2-2clear: CLEAR]. The error<br />
count is cleared at the same time.<br />
Memory failure (RAM) (70)<br />
The alarm occurs when the driver’s RAM memory fails. It is impossible to clear the alarm.<br />
Memory failure (EEPROM) (71)<br />
The alarm occurs when the driver’s EEROM memory fails. It is impossible to clear the alarm.<br />
CPU failure (76)<br />
The alarm occurs when the driver’s CPU fails. It is impossible to clear the alarm.<br />
