Name Definition
SSCNET cable
communication error
Input command pulse is
too high.
SSCNET cable fault
Load exceeded overload
protection characteristic
of servo amplifier.
Load ratio 200%:
85s or more
Machine collision or like
caused max. output
current to flow
successively for several
seconds.
Servomotor locked:
1s or more
1. SSCNET cable is disconnected.
2. SSCNET cable fault (open cable or short circuit).
3. Noise entered the SSCNET cable.
4. The terminal connector is disconnected.
5. The same No. exists in the servo amplifier side axis setting.
1. Command of higher than servomotor maximum speed was given.
2. Noise entered the SSCNET cable.
3. AD75 faulty
1. SSCNET cable is disconnected.
2. SSCNET cable fault.
3. Printed board faulty
4. The terminal connector is disconnected.
1. Servo amplifier fault caused the parameter setting to be rewritten.
2. There is parameter set to outside setting range by AD75.
1. Servo amplifier is used in excess of its continuous output current.
2. Servo system is instable and hunting.
3. Machine struck something.
4. Wrong connection of servomotor.
Servo amplifier's output terminals U, V, W do not match
servomotor's input terminals U, V, W.
5. Encoder faulty.
1. Machine struck something.
2. Wrong connection of servomotor.
Servo amplifier's output terminals U, V, W do not match
servomotor's input terminals U, V, W.
3. Servo system is instable and hunting.
4. Encoder faulty.
