The set value of the parameter issmall.4. Overshooting occurs because theinertia of jig, etc., is large.Brake clamp droop waiting1. Overload.2. The set value of the parameter issmall.ST Signal alarm1. Start input is kept ON at externalequipment.2. ST and INCOM are short- circuited.SP Signal alarm1. Stop input is kept ON at externalequipment.2. SP cable is broken.ZERO pulse waiting1. The acceleration constant is small.2. CB1cable is broken.3. Motor encoder is incorrect.D e t a i l sC o u n t e r m e a s u r e sThe motor starts rotation by an external force duringclamping, exceeding the set value.1. Raise the air pressure.2-1. Lower the cutting speed of the machine.2-2. Reduce the amount of cutting.3. Raise the set value of PRM015.4-1. Servo adjustment.4-2. Lower the feedrate.The parameter does not become less than set valueeven if 5 seconds elapses after the distribution isfinished.1. Reduce the load.2. Make the set value for PRM015 higher.ST signal is not turned off when more than 5seconds passed since the power gets ON.1. Release the status that keeps the starting input.2. Replace the cable CB3 if the cable is incorrect.SP signal is not turned ON when more than 5seconds passed since the power gets ON.1. Release the status that keeps the stop input.2. Replace the cable CB3.Zero pulse is not checked in MZRN even if the tablerotates by the constant angular.1. Raise the acceleration constant.2. Replace CB1 cable.3. Replace the motor.KITAGAWA I1-11
