001F Machine side dtc: Commu error
Details
An error was detected in the communication with the machine side detector.
- Servo stop method: Dynamic stop
- Spindle stop method: Coast to a stop
0021 Machine side dtc: No signal
Details
In the machine side detector, ABZ-phase feedback cannot be returned even when the motor moves.
- Servo stop method: Dynamic stop
- Spindle stop method: Coast to a stop
0022 Detector data error
Details
An error was detected in the feedback data from the position detector.
- Servo stop method: Dynamic stop
0023 Excessive speed error
Details
The state that there is a difference between the actual speed and command speed continued for
longer than the excessive speed deviation timer setting.
- Spindle stop method: Coast to a stop
0024 Grounding
Details
The motor power cable is in contact with FG (Frame Ground).
- Servo stop method: Dynamic stop
- Spindle stop method: Coast to a stop
0025 Absolute position data lost
Details
The absolute position data was lost in the detector.
- Servo stop method: Initial error
0026 Unused axis error
Details
In the multi-axis drive unit, there is an axis set to free, and the other axis detected a power module
error.
- Servo stop method: Dynamic stop
- Spindle stop method: Coast to a stop
0027 Machine side dtc: Error 5
Details
An error was detected by the detector connected to the machine side.
The error details are different according to the detector type.
- Servo stop method: Dynamic stop
- Spindle stop method: Coast to a stop
[Detector alarm (Servo drive unit)]
- MDS-B-HR() Scale not connected
- AT343, AT543, AT545(Mitsutoyo) CPU error
- LC193M, LC493M, LC195M, LC495M, RCN223M, RCN227M, RCN727M, RCN827M, EIB
Series(HEIDENHAIN) CPU error
- MPRZ Scale(MHI) Absolute value detection fault
- SAM/SVAM/GAM/LAN Series (FAGOR) CPU error
[Detector alarm (Spindle drive unit)]
- MDS-B-HR() Connection error
- EIB Series(HEIDENHAIN) CPU error
(Note) A driver processes all reset types of alarms as "PR". However, "AR" will be applied according to
the detector.
