7. List of Alarms
An internal memory error was detected in the linear scale of a linear
servo system.
An error was detected in communication data with the motor end
detector or with the linear scale of a linear servo system. Or the
communication was interrupted.
Over-regeneration detection level became over 100%. The
regenerative resistor is overloaded.
The motor was detected to rotate at a speed exceeding the allowable
speed.
Overcurrent protection function in the power module has started its
operation.
PN bus voltage in main circuit exceeded the allowable value.
An error was detected in the data received from the CNC.
The travel command data that was received from the CNC was
excessive.
The communication with the CNC was interrupted.
An incorrect parameter was detected among the parameters
received from the CNC at the power ON.
An error was detected in the communication frames received from
the CNC.
An error was detected in the axis information data received from the
CNC.
Excessive current was detected in the motor drive current.
Thermal protection function in the power module has started its
operation.
An error was detected in the regenerative transistor or in the
regenerative resistor.
The spindle motor failed to rotate faster than 45 r/min, even when the
max. torque command was given.
1. The spindle motor speed feedback was detected to be
accelerated exceeding the commanded speed.
2. The spindle motor was detected to be rotated at a speed
exceeding the parameter value, while the speed command was
"0" (including the case of operation stoppage during the position
control).
A difference between the speed command and speed feedback was
detected to exceed the setting amount or setting time in a constant
speed operation.
An error was detected in the motor switching signals that were
received from the detector selection unit, while controlling one drive
unit and two motors.
An error was detected in the communication with the detector
selection unit, while controlling one drive unit and two motors.
