2-Phase Closed-Loop Stepper otor Troubleshooting 1. When motor does not rotate 1Check the connection status between controller and driver, and pulse input specifications (voltage, width). 2Check the pulse and direction signal are connected correctly. 2. When motor rotates to the opposite direction of the designated direction 1When RUN mode is 1-pulse input method, CCW input is for forward, is for backward. 2When RUN mode is 2-pulse input method, check CW and CCW pulse input are changed or not. 3. When motor drive is unstable 1Check that driver and motor are connected correctly. 2Check the driver pulse input specifications (voltage, width). Proper Usage 1. Do not disassemble or modify the product. It may cause malfunction due to small dregs. Once disassembling the motor, its performance would significantly decline. 2. Do not impact the motor. The air-gap, the distance between rotator and stator is processed as.5mm, but if it is impacted, the balance of air-gap can be broken and it may cause a malfunction. This encoder consists of precision components. Therefore, if it is dropped or has strong shock, it may lose the function or generates wrong output pulses. 3. Using at low temperature Using motors at low temperature may cause reducing maximum starting / driving characteristics of the motor due to decreased ball bearing's grease consistency. Start the motor in a steady manner since motor's torque is not to be influenced. 4. Temperature rise The surface temperature of motor shall be under 1 and it can be significantly increased by operation conditions (ambient temperature, drive speed, drive duty ratio, etc). In this case, use the cooling fan to lower the temperature forcedly. It may cause for motor power cable to be damaged by fire, for inner ball-bearing of motor to be shortening the life cycle or for the unit to malfunction. 5. Insulation resistance measurement, Dielectric strength test When executing insulation resistance measurement or dielectric strength test when motor and driver are connected, it may cause damage to the unit. 6. Encoder wire connection 1Do not draw the wire with over strength 3N after wiring. 2If wire encoder cable with high voltage line or power cable in the same conduit, it may cause a malfunction or mechanical problem. Please wire it separately or use separated conduit. 3Check the cable type and response frequency before using the unit. The cable length should be as short as possible. If not, it may cause increase cable resistance, residual voltage, and output waveform noise 4ust connect the shield cable to the F.G. terminal. 7. aintenance, Inspection For using motor, it is recommended to maintenance and inspection regularly. If motor has error, do not use the motor. Take maintenance and inspection before using it. aintenance and inspection items are as below. 1Unwinding bolt and connection parts for the unit installation and load connection 2Strange sound from ball bearing of the unit 3Damage and stress of lead cable of the unit 4Connection error with driver 5Inconsistency between the axis of motor output and the center, concentric (eccentric, declination) of the load, etc. 8.
