If the BATTERY LOW warning is output, save the machining programs, tool data and
parameters to an input/output device, and then replace the battery. If the BATTERY
alarm occurs, the machining programs, tool data and parameters may be damaged.
After replacing the battery, reload each data item.
If the axis overruns or makes an abnormal noise, press the EMERGENCY STOP
button immediately, and stop the axis.
When setting the parameter not to check the overheat, the control unit and the
communication terminal may not be controlled because of overheat.
In such case, axis runaway may cause a machine breakage, an accident resulting in
injury or death, or device breakage.
To prevent the serious results, ordinarily set the parameters so that the overheat
check is valid.
Do not apply voltages on the connector other than those indicated in Connection and
Maintenance manual. Doing so may lead to destruction or damage.
Incorrect connections may damage the devices, so connect the cables to the
specified connectors.
Do not connect or disconnect the connection cables between each unit while the
power is ON.
Do not connect or disconnect any PCB while the power is ON.
Do not replace the battery while the power is ON.
Do not short-circuit, charge, overheat, incinerate or disassemble the battery.
Dispose of the spent battery according to local laws.
To change the control mode to the High-gain amp (MDS-B-V14/V24) mode after
replacement of the Standard amp (MDS-B-V1/V2), it is need to change the
parameters and to adjust the servo parameters to fit to the High-gain amp.
Mode change between the Standard amp mode and the High-gain amp mode is
actually performed when the power (200V) is turned ON. Thus, when changing some
parameters unique to each amp, an alarm "7F" occurs and requests to turn the power
ON again.
Note that the alarm "7F" may occur when the amp is mounted on the machine for the
first time.
When the alarm "7F" occurs, turn the power ON again.
The alarm "7F" may not occur at second turning ON or later unless the above-
mentioned parameters are changed.
With MDS-C1 series, only the serial encoder is applied as the motor end detector.
Thus, OHE/OHA type detector cannot be used as the motor end detector.
Do not make remarkable adjustments or changes of the parameters as the operation
may became unstable.
