0041 Feedback error 3
Details
Either a missed feedback pulse in the motor side detector or an error in the Z-phase was detected in
the full closed loop system.
- Servo stop method: Dynamic stop
- Spindle stop method: Coast to a stop
0042 Feedback error 1
Details
Either a missed feedback pulse in the position detection or an error in the Z-phase was detected. Or
the distance-coded reference check error exceeded the allowable value when the distance-coded
reference scale was used.
- Servo stop method: Dynamic stop
- Spindle stop method: Coast to a stop
0043 Feedback error 2
Details
An excessive difference in feedback was detected between the machine side detector and the motor
side detector.
- Servo stop method: Dynamic stop
- Spindle stop method: Coast to a stop
0045 Fan stop
Details
An overheat of the power module was detected during the cooling fan stopping.
- Servo stop method: Dynamic stop
- Spindle stop method: Coast to a stop
0046 Motor overheat
Details
Either the motor or the motor side detector detected an overheat.
Or, the thermistor signal receiving circuit of the linear motor or DD motor was disconnected.
Or, the thermistor signal receiving circuit was short-circuited.
- Servo stop method: Deceleration stop enabled
- Spindle stop method: Deceleration stop enabled
0048 Motor side dtc: Error 5
Details
An error was detected by the detector connected to the main side.
The error details are different according to the connected detector.
- Servo stop method: Dynamic stop
- Spindle stop method: Coast to a stop
