7.3.6 Troubleshooting for E-Cam
If the E-Cam cannot operate normally, follow these steps to troubleshoot:
1.
Servo drive control mode: make sure the control mode is PR mode and the system is in
the Servo On state.
2.
Pulse source of master axis: check the setting of P5.088.Y for the source of the master
axis. Use P5.086 or monitoring variable 059 to read the pulse count of the master axis.
If selecting CN1 as the input connector, use P5.018 to monitor the pulse count; if selecting
CN5 as the input connector, use P5.017 to monitor the pulse count.
3.
E-Cam curve: read the E-Cam curve data in the data array. Make sure the E-Cam curve is
correct and check the settings for P5.081 (the start address of the E-Cam data array) and
P5.082 (E-Cam segment number).
4.
E-Cam gear ratio and scaling of E-Cam curve: check the master axis E-Gear ratio
(P5.084 / 5.083) and the slave axis E-Gear ratio (P1.044 / P1.045). Check the E-Cam curve
scaling (P5.019). If the proportion is set too small, the motor operation is too subtle to be
monitored even when E-Cam is operating. In this case, use the scope in the ASDA-Soft to
see if the motor is slightly rotating.
5.
Clutch status: read P5.088.D to obtain the current status of the clutch.
If P5.088.D = 0, it means the clutch is disengaged. Check the engagement setting
(P5.088.Z).
If P5.088.D = 1, it means the clutch is engaged and the slave axis operates based on the
pulses from the master axis. If the disengagement condition is determined by the DI
(P5.088.U = 1), check the timing for triggering the DI to on and off. If the disengagement
condition is set to “Immediate stop after disengagement” (P5.088.U = 2) or “Decelerate to
stop after disengagement” (P5.088.U = 6), check the pulse number of disengaging time
(P5.089).
