1. The PUL/DIR control signal is too weak causing by too large current limit resistor in
series with the driver.
2. The PUL/DIR control signal is interfered.
3. Wrong motor connection.
4. Motor broken or something wrong with motor coil.
5. Current setting of the motor driver is too small.
6. The DMC5400 failure; contact Leadshine for help or repair.
1. The encoder signal is not a TTL signal. Use an encoder whose signals are TTL
compatible.
2. Encoder wiring is wrong. Wiring encoder correctly and fix wires firmly.
3. Encoder has not been powered correctly. Check the power supply for encoder.
4. The feedback signals are corrupted by noise signal (s). Please increase noise
immunity of feedback signals, such as using shielded cable(s) and good grounding.
5. Called a wrong function or right function but with wrong parameter(s). Please call
the correct function with correct parameter(s).
6. Encoder failure.
7. The DMC5400 failure; contact Leadshine for help or repair.
1. Wrong wiring. Wiring correctly and fix wires firmly.
2. Called a wrong function or right function but with wrong parameter(s). Please call
the correct function with correct parameter(s).
3. Trigger signal is a dither signal.
4. The DMC5400 failure; contact Leadshine for help or repair.
1. Wrong wiring. Wiring correctly and fix wires firmly.
2. Called a wrong function or right function but with wrong parameter(s). Please call
the correct function with correct parameter(s).
3. Input device(s)/sensor(s) failure.
4. Input signal is interfered.
5. The DMC5400 failure; contact Leadshine for help or repair.
1. Wrong wiring. Wiring correctly and fix wires firmly.
2. Called a wrong function or right function but with wrong parameter(s). Please call
